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 A27 Grade 60-30 Cast Carbon Steel Flange Product Information -:- For detailed product information, please contact sales. -: ASTM A27 Grade 60-30 Cast Carbon Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

ASTM A27 Grade 60-30 Cast Carbon Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: ASTM A27 Grade 60-30 Cast Carbon Steel** #### **Product Overview** ASTM A27 Grade 60-30 is a general-purpose cast carbon steel grade known for its good combination of strength, ductility, and cost-effectiveness. It is one of the most commonly used grades of carbon steel casting for non-critical, general application components. The designation "60-30" refers to its minimum tensile strength of 60 ksi (415 MPa) and minimum yield strength of 30 ksi (205 MPa). It is typically supplied in the as-cast condition without heat treatment, making it an economical choice for a wide range of industrial applications. **Key Advantages:** * **Cost-Effective:** A versatile and economical choice for a wide range of general-purpose components. * **Good Machinability:** Readily machinable in the as-cast or annealed condition. * **Adequate Strength & Ductility:** Provides a reliable balance of mechanical properties for many non-severe service conditions. * **Good Weldability:** Can be welded using standard procedures, though precautions are recommended. --- #### **International Standard** The manufacturing and testing of this product are governed by the latest version of: * **ASTM A27 / A27M:** Standard Specification for Steel Castings, Carbon, for General Application. This standard ensures the material meets specified chemical and mechanical property requirements. --- #### **Chemical Composition (Heat Analysis, %)** The chemical composition is a key factor in achieving the required mechanical properties. The following table details the requirements for Grade U-60-30 (as-cast) and Grade J-65-35 (which may be heat-treated). | Element | Grade U-60-30 (As-Cast) | Grade J-65-35 (May be Heat-Treated) | | :--- | :--- | :--- | | **Carbon (C)** | 0.25% max | 0.25% max | | **Manganese (Mn)** | 0.70% max | 0.70% max (0.60-0.90 for heat-treated) | | **Phosphorus (P), max** | 0.05% | 0.05% | | **Sulfur (S), max** | 0.06% | 0.06% | | **Silicon (Si)** | 0.80% max (0.60% min for killed steel) | 0.80% max (0.60% min for killed steel) | | *Note: Grade U-60-30 is typically supplied in the as-cast condition. The "U" designation indicates it is unspecified regarding heat treatment.* | --- #### **Mechanical Properties** Mechanical properties are verified by testing separately cast test bars. | Property | Grade U-60-30 (As-Cast) | Grade J-65-35 (Heat-Treated) | Unit | | :--- | :--- | :--- | :--- | | **Tensile Strength, min** | 415 | 450 | MPa (60 ksi) | (65 ksi) | | **Yield Strength, min** | 205 | 240 | MPa (30 ksi) | (35 ksi) | | **Elongation in 2 in (50 mm), min** | 24 | 26 | % | | **Reduction of Area, min** | 35 | 35 | % | --- #### **Physical Properties (Typical Values)** * **Density:** 7.85 g/cm³ (0.284 lb/in³) * **Modulus of Elasticity:** 200 GPa (29,000 ksi) * **Poisson's Ratio:** 0.29 * **Coefficient of Thermal Expansion:** 11.5 x 10⁻⁶/°C (20-100°C) --- #### **Heat Treatment** * **Grade U-60-30:** This grade is typically supplied in the **as-cast** condition, meaning it has not undergone a specific heat treatment after solidification. * **Grade J-65-35:** This grade may be supplied in the heat-treated (normalized or annealed) condition to achieve higher mechanical properties. Heat treatment can improve ductility and toughness and relieve internal stresses from the casting process. --- #### **Product Applications** ASTM A27 Grade 60-30 is suitable for a wide array of general industrial components that operate under moderate stress and non-critical conditions. * **Valve and Pump Bodies:** For water, oil, and low-pressure steam services. * **Pipe Fittings:** Flanges, elbows, and other general service fittings. * **Industrial Machinery Components:** Machine bases, gear blanks, housings, and non-critical frames. * **Railroad Components:** Non-critical parts for rolling stock. * **Marine Hardware:** Low-stress deck fittings and hardware. * **Construction Equipment:** Brackets, covers, and other structural components not subject to high impact or fatigue loads. --- #### **Fabrication & Welding Notes** * **Welding:** Welding is possible but requires care due to the carbon content and as-cast structure. * Use low-hydrogen welding electrodes and processes. * **Preheating** is highly recommended, typically in the range of 200-400°F (95-205°C), to prevent cracking, especially in thicker sections. * **Post-Weld Heat Treatment (Stress Relieving)** is often advisable to relieve residual stresses in the weld area. * **Machining:** Offers good machinability, especially if normalized or annealed. In the as-cast state, the surface scale and slight variations in hardness can affect tool life. * **Limitations:** Not recommended for high-impact, high-fatigue, or high-temperature service. Its properties are generally inferior to those of heat-treated alloy steel castings like ASTM A148. --- **Disclaimer:** This datasheet is for informational purposes only.
