1,We Manufacturing processes are primarily classified into four types: 1:Forging, 2:Casting, 3:Cutting, 4:Rolling. 2,We can manufacture in accordance with these standards. Standards: GB Series (Chinese Standards), JB Series (Machinery Standards), HG Series (Chemical Industry Standards), ASME B16.5 (American Standards), BS4504 (British Standards), DIN (German Standards), and JIS (Japanese Standards). Internationally, there are two primary systems of pipe flange standards: the European system, represented by the German DIN standards (including those of the former Soviet Union), and the American system, represented by the US ANSI pipe flange standards. Other common standards include: the Chinese Ministry of Machinery Industry standards (JB series), the Ministry of Chemical Industry standards (HG series), the Chinese National Standard *GB/T 9112–9124-2010 Steel Pipe Flanges*, as well as US standards (ASME B16.5), British standards (BS4504), German standards (DIN), Japanese standards (JIS), and marine standards (CBM), among others. The nominal pressure ratings for the PN series are designated by "PN" and comprise the following nine levels: PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160. The nominal pressure ratings for the Class series are designated by "Class" and comprise the following six levels: Class150, Class300, Class600, Class900, Class1500, and Class2500.

A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: ASTM A607 Steel Flange, grade 50, hot rolled Product Information -:- For detailed product information, please contact sales. -: ASTM A607 Steel Flange, grade 50, hot rolled Synonyms -:- For detailed product information, please contact sales. -:

ASTM A607 Steel, grade 50, hot rolled Product Information -:- For detailed product information, please contact sales. -: ## **Product Datasheet: ASTM A607 Grade 50 Hot-Rolled Steel Sheet & Strip** **Product Overview** ASTM A607 Grade 50 is a **hot-rolled, high-strength, low-alloy (HSLA) steel sheet and strip** engineered for applications requiring a balance of **50 ksi minimum yield strength, atmospheric corrosion resistance, and good weldability**. As part of the A607 specification, the hot-rolled variant offers an economical and robust solution for structural and forming applications where the superior surface finish of cold-rolled material is not required. The mandatory copper content ensures approximately **twice the atmospheric corrosion resistance of plain carbon steel**, making it a true "weathering steel" within the sheet and strip category. This grade is strengthened through columbium (niobium) or vanadium microalloying and is supplied in the hot-rolled condition. **Key International Standards** * **Primary Standard:** **ASTM A607** - Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Columbium or Vanadium, or Both, Hot-Rolled and Cold-Rolled. * **Governing Specification:** This product conforms to the requirements for **Grade 50** in the **hot-rolled** condition as defined in ASTM A607. * **Type Classification:** **Type 1 (Columbium)** or **Type 2 (Vanadium)**. The type denotes the primary microalloying element used for grain refinement and strengthening. * **Corrosion Resistance:** Requires a **minimum copper content of 0.20%**, providing a guaranteed improvement in atmospheric corrosion resistance compared to non-copper-bearing steels. This is a standard, non-optional feature of all A607 grades. * **Material Condition:** Supplied in the **hot-rolled** condition, typically with a mill scale surface. It may be available as **HRPO (Hot Rolled, Pickled and Oiled)** for improved surface quality for painting. **Chemical Composition (Weight % - ASTM A607 Grade 50 Requirements)** Chemistry is balanced for strength, corrosion resistance, and formability. | Element | Requirement (Max, unless noted) | Purpose & Note | | :--- | :--- | :--- | | **Carbon (C)** | 0.23% | Controlled for strength and weldability. | | **Manganese (Mn)** | 1.35% | Solid solution strengthening. | | **Phosphorus (P)** | 0.04% | Impurity control. | | **Sulfur (S)** | 0.05% | Impurity control. | | **Silicon (Si)** | 0.30% | Deoxidizer. | | **Copper (Cu)** | **0.20% min** | **Mandatory** for atmospheric corrosion resistance. | | **Columbium (Cb/Nb)** | 0.05% Max (Type 1) | Grain refiner for Type 1. | | **Vanadium (V)** | 0.15% Max (Type 2) | Precipitation strengthener for Type 2. | | **Carbon Equivalent (C.E. IIW)** | -- | Typically 0.38 - 0.45, indicating **good weldability**. | **Physical & Mechanical Properties** | Property | Requirement (ASTM A607 Grade 50) | Characteristics of Hot-Rolled Condition | | :--- | :--- | :--- | | **Yield Strength (Min)** | 50 ksi (345 MPa) | Typically 55 - 65 ksi (380 - 450 MPa) | | **Tensile Strength** | 65 ksi (450 MPa) min | Typically 70 - 80 ksi (483 - 552 MPa) | | **Elongation in 2" (Min)** | 20% | Good ductility for moderate forming. | | **Surface Finish** | Standard **hot-rolled mill scale**. | Characteristic oxide layer; can be supplied pickled and oiled (HRPO) for painting. | | **Dimensional Tolerance** | Conforms to **ASTM A568** for hot-rolled sheet. | Standard commercial tolerances. | | **Atmospheric Corrosion Resistance** | ~2x that of plain carbon steel (e.g., A1011). | Integral property due to mandatory copper content; forms protective patina. | | **Key Feature** | **Economical Weathering HSLA Sheet:** Provides the fundamental combination of 50 ksi yield strength, proven weldability, and guaranteed atmospheric corrosion resistance in a cost-effective hot-rolled product form, ideal for rugged, exposed applications. | **Product Applications** ASTM A607 Grade 50 hot-rolled sheet is specified for structural and forming applications exposed to the atmosphere where painting may be optional or where a protective coating is used. * **Heavy Equipment & Machinery:** Cabs, canopies, fenders, and structural panels for agricultural, construction, and mining equipment. * **Transportation:** Truck and trailer body components, dump truck beds, shipping container panels, and railcar side sheets. * **Building & Construction:** Roof and floor decking, wall panels (often painted), industrial door panels, and light structural members. * **Storage Tanks & Containers:** For non-pressure, atmospheric storage where corrosion resistance is beneficial. * **Utility & Electrical Enclosures:** For outdoor applications. **Advantages & Fabrication Notes** * **Excellent Weldability:** The low carbon equivalent makes it highly weldable using all common processes (SMAW, GMAW, FCAW, SAW). Low-hydrogen practice is recommended. Preheating is generally not required for thin to moderate thicknesses. * **Good Formability:** Suitable for **moderate cold forming** such as bending, roll-forming, and punching. It is more formable than hot-rolled carbon steel of similar strength due to its fine-grained microalloyed structure. * **Corrosion Resistance in the Base Metal:** Unlike painted carbon steel, scratches or coating damage on A607 will result in the formation of a protective patina rather than rapid, expansive red rust, offering better long-term durability. * **Surface Preparation for Coating:** If painting, **mill scale must be removed** via abrasive blasting or pickling to ensure coating adhesion. Specifying **HRPO (Hot Rolled, Pickled and Oiled)** condition eliminates mill scale and provides a clean, ready-to-paint surface. * **Cost-Effectiveness:** Offers a lower-cost entry point to weathering steel performance compared to cold-rolled A607 or hot-rolled plate products like A588. **Disclaimer:** This datasheet describes **ASTM A607 Grade 50 Hot-Rolled** sheet and strip. For procurement, specify: **ASTM A607, Grade 50, Type (1 or 2, if relevant), hot-rolled, and surface condition (e.g., with mill scale, HRPO)**. Reference **ASTM A568** for dimensional tolerances. **Key Comparisons:** * **vs. ASTM A606 Type 4:** A607 Grade 50 is a **property-based** weathering steel (guaranteed YS 50 ksi), while A606 Type 4 is a **chemistry-based** weathering steel with a typical yield of 50 ksi but not guaranteed by the standard. They are often considered commercial equivalents. * **vs. ASTM A1011 HSLAS Grade 50:** A1011 is an HSLA sheet **without** guaranteed corrosion resistance. A607 includes copper and is a weathering grade. * **vs. A588 Plate:** A607 sheet is the coiled sheet/strip product form equivalent to A588 plate chemistry and performance. This material is the standard choice for fabricating durable, unpainted or painted components that will face outdoor exposure, offering a lifecycle cost advantage over painted plain carbon steel. -:- For detailed product information, please contact sales. -: ASTM A607 Steel, grade 50, hot rolled Specification Dimensions Size： Diameter 20-1000 mm Length <4722 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A607 Steel, grade 50, hot rolled Properties -:- For detailed product information, please contact sales. -:
