SA 285 Grade C refers to a low to intermediate tensile strength carbon steel plate, primarily used for welded pressure vessels, storage tanks, boilers, and heat exchangers, known for good weldability and formability at moderate temperatures and pressures. It offers a tensile strength range of 55-75 ksi (380-515 MPa) and a minimum yield strength of 30 ksi (205 MPa). The Sa 285 Grade C Plate possesses low to intermediate tensile strength and it is basically a pressure vessel grade of stainless steel. The Astm A285 C material is used in the pressure vessel and boiler tank fabrication process, and they should not be considered for high pressure applications. The Astm A285 Grade C Plate has good weldability, and hence they can be welded using the conventional procedures.

What is SA 285 GR C material?
SA 285 Gr C Pressure Vessel Plates is a carbon steel plate with a low to intermediate strength, it possesses good weldability & formability. A285 Grade C Plates has excellent resistance to corrosion, & it is suitable for a wide range of applications due to its good toughness & ductility.
What is the difference between SA 285 GR C and A36?
A285 Grade C has low to medium tensile strength between 380 to 515 MPa, whereas the tensile strength of A36 material ranges between 400 to 500 Mpa. This is due to the variation in their chemical composition.
What is the difference between SA 516 70 and SA 285 Grade C?
SA 516 GR 70 offers higher tensile strength (485-620 MPa) and HIC resistance for high-pressure vessels, while SA 285 GR C has lower strength (310-450 MPa) for low-pressure applications.At Gangsteel, we manufacture ASME SA 516 GR 70 plates to meet demanding standards for critical industries like oil and gas.
What is SA 285 material?
SA 285 Gr C Pressure Vessel Plates is a carbon steel plate with a low to intermediate strength, it possesses good weldability & formability. A285 Grade C Plates has excellent resistance to corrosion, & it is suitable for a wide range of applications due to its good toughness & ductility.
What is the ASME SA 285 Grade C equivalent to?
ASME SA 285 Gr C equivalents include ASTM A285 Grade C, EN P235GH, DIN HI, JIS SPV235, BS 161-360A, GB Q245R, with yield ~205-235 MPa for low-pressure vessels.
What is the difference between SA 285 GR C and SA 283 GR C?
SA 283 Gr C is for general structures and low-pressure tanks, while SA 285 Gr C is for pressure vessels and boilers with stricter chemical controls. They are not always interchangeable due to application restrictions. Gangsteel's plates support both with certifications.
What is the difference between SA and ASTM?
ASTM provides general material standards across industries and products, such as carbon steel pipes, alloy tubes, and stainless steel sheets, while ASME SA focuses on materials for pressure vessels, boilers, and other high-stress applications, including high-pressure pipes and heat exchanger tubes.
What does SA stand for in material?
Specific surface area (SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, (with units of m2/kg or m2/g). Alternatively, it may be defined as SA per solid or bulk volume (units of m2/m3 or m−1).
