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. -: AISI 1005 Steel Flange Product Information -:- For detailed product information, please contact sales. -: AISI 1005 Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

AISI 1005 Steel Product Information -:- For detailed product information, please contact sales. -: ## **Product Specification: AISI 1005 Ultra-Low Carbon Steel** ### **Product Designation** * **Standard Name:** AISI 1005 / SAE 1005 * **UNS Number:** G10050 * **Type:** **Ultra-Low Carbon, Non-Hardenable Plain Carbon Steel** * **Primary Forms:** Hot-rolled or cold-rolled sheet, strip, wire, rod, and bar. * **Key Characteristic:** Exceptionally soft, ductile, and weldable with very low strength in the as-rolled/annealed state. ### **Overview** AISI 1005 is a commercially pure, ultra-low carbon steel at the extreme low end of the carbon steel spectrum. Its defining feature is an extremely low carbon content, resulting in a microstructure that is almost entirely **ferritic**. This gives it outstanding ductility (formability), excellent weldability, and high electrical and thermal conductivity, but very low tensile strength and no capacity for strengthening by heat treatment. It is a fundamental material for deep drawing, cold forging, and applications where maximum softness and magnetic properties are required. --- ### **1. Chemical Composition (Typical % by Weight, AISI/SAE Standard)** The composition is defined by minimal alloying, maximizing iron content. | Element | Content (%) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.04 max | **Defining element.** Kept extremely low to ensure a soft, single-phase ferritic structure, maximizing ductility and eliminating hardenability. | | **Manganese (Mn)** | 0.35 max | Aids in deoxidation during steelmaking; minimal strengthening effect. | | **Phosphorus (P)** | 0.040 max | Impurity; affects cold workability if too high. | | **Sulfur (S)** | 0.050 max | Impurity; affects surface finish and weldability. | | **Silicon (Si)** | * | Typically very low or residual; may be specified for specific deoxidation practice (e.g., rimmed, capped, killed). | | **Iron (Fe)** | ~99.5% min | Balance. The high purity contributes to its magnetic and conductive properties. | *Note: Silicon content varies based on deoxidation practice (Rimmed, Capped, or Killed).* --- ### **2. Physical & Mechanical Properties (Annealed/Cold-Rolled State)** **A. Physical Properties** * **Density:** 7.87 g/cm³ (0.284 lb/in³) * **Elastic Modulus (E):** 200 GPa (29,000 ksi) * **Poisson's Ratio:** 0.29 * **Electrical Resistivity:** ~12.5 μΩ·cm (very low, excellent conductor) * **Thermal Conductivity:** ~64 W/m·K (very high) * **Magnetic Properties:** Excellent; exhibits high magnetic permeability and low coercivity, making it a **soft magnetic material**. **B. Mechanical Properties (Typical, Annealed)** *Properties are highly dependent on cold work (temper).* * **Yield Strength (Ann.):** 150 - 275 MPa (22 - 40 ksi) * **Tensile Strength (Ann.):** 285 - 345 MPa (41 - 50 ksi) * **Elongation in 50 mm:** **35% - 45%** (Exceptionally high) * **Hardness (Brinell):** ~95 HB (Rockwell B ~55) * **Machinability:** **Poor** in the annealed state due to extreme gumminess and low hardness. It forms long, stringy chips. * **Hardenability:** **None.** Cannot be strengthened by quenching. * **Work Hardening:** Can be moderately strengthened by cold working (drawing, rolling). --- ### **3. Product Applications** AISI 1005 is used where extreme formability, weldability, or specific electromagnetic properties are paramount, and strength is a secondary concern. * **Deep Drawing & Severe Forming:** * Enclosures, housings, and cans that require complex, deep-drawn shapes without cracking. * **Cold Forging & Extrusion:** * Rivets, screws, and simple fasteners produced by cold heading. * **Wire Products:** * Tie wire, baling wire, and wire for fencing where high ductility is needed for twisting and knotting. * **Electrical & Magnetic Cores:** * Laminations for small transformers, solenoids, relay cores, and other electromagnetic devices where low hysteresis loss (soft magnetism) is critical. *(Often supplied as fully processed electrical steel with specific insulation coatings)*. * **Welded Tubes & Conduit:** * For non-structural applications like electrical conduit or furniture, where easy welding and bending are key. * **Base Metal for Coating:** * Substrate for galvanizing (zinc coating) or electroplating (tin, chromium, nickel) due to its clean, uniform surface. --- ### **4. International Standards & Designations** AISI 1005 is a basic grade with direct equivalents in most global standards. | Standard System | Designation | Notes / Key Comparison | | :--- | :--- | :--- | | **SAE / AISI (USA)** | **SAE 1005 / AISI 1005** | The standard designation. | | **UNS (USA)** | **G10050** | Unified Numbering System. | | **ASTM (USA)** | **ASTM A366 (Sheet), A569 (Strip), A108 (Bar)** | Common product form specifications. | | **DIN / EN (Germany/EU)** | **DC01 (EN 10130), 1.0332** | **DC01** is the direct equivalent for cold-forming sheet. **RRSt 14-2.1** is an older designation. | | **JIS (Japan)** | **SPCC, S10C** | **SPCC** (cold-rolled sheet) and **S10C** (bars) are the common equivalents. | | **GB (China)** | **Q195, 08F, 10** | **08F** or **10** are common designations for ultra-low carbon steel for deep drawing. | | **ISO** | **ISO 3573: CR1** | Classification for commercial quality cold-rolled carbon steel sheet. | --- ### **Key Considerations & Processing** 1. **Formability:** Excellent for deep drawing, roll forming, and bending. **Strain Aging:** Can be prone to slight aging (increase in yield strength and loss of ductility) over time after cold working. 2. **Welding:** **Outstanding.** Can be welded by all common processes without pre-heat or post-heat. No risk of hardening in the heat-affected zone (HAZ). 3. **Strength Limitation:** Not suitable for any structural or load-bearing application. Strength can only be increased through cold work (work hardening). 4. **Surface Finish:** Often supplied with a smooth, clean finish suitable for painting or plating. ### **Summary** **AISI 1005 is the quintessential ultra-low carbon, high-ductility steel.** Its virtual lack of carbon and alloying elements makes it the material of choice for applications demanding **maximum formability, easy welding, or excellent soft magnetic characteristics**. While it possesses negligible strength and poor machinability, its value lies in its ability to be severely deformed without failure and its favorable electromagnetic properties. It serves as a critical base material for the electrical industry, container manufacturing, and general fabrication where shaping, not load-carrying, is the primary function. Its global equivalents, such as **EN DC01** and **JIS SPCC**, confirm its fundamental role in manufacturing worldwide. -:- For detailed product information, please contact sales. -: AISI 1005 Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4733 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. -: AISI 1005 Steel Properties -:- For detailed product information, please contact sales. -:
