304 Plate Flange: Specifications, Common Sizes, Material Composition, Mechanical Properties, and Types Offered by SSM

304 Stainless Steel Plate Flange Specifications

A 304 Plate Flange is a type of flange made from 304 stainless steel. It conforms to various standards, with ASTM A182 and ASME B16.5 being common standards for flanges.

Common Sizes

304 Plate Flanges come in various sizes to accommodate different piping needs. Common sizes include 1/2 inch, 3/4 inch, 1 inch, 2 inches, up to 24 inches in diameter, and other sizes as per customer requirements.

Material Composition

– Chromium (Cr): Approximately 18%. Provides excellent corrosion resistance.
– Nickel (Ni): Approximately 8%. Enhances corrosion resistance and durability.
– Carbon (C): Low carbon content, usually less than 0.08%. Minimizes susceptibility to intergranular corrosion.
– Silicon (Si): Typically less than 1%. Aids in improving manufacturing processes.
– Manganese (Mn): Typically less than 2%. Contributes to uniformity.
– Phosphorus (P) and Sulfur (S): Kept at low levels to enhance machinability and corrosion resistance.

Mechanical Properties

– Tensile Strength: Typically around 70,000 psi (approximately 483 MPa).
– Yield Strength: Typically around 25,000 psi (approximately 172 MPa).
– Elongation: Typically around 40%.
