What is SA285 Gr A vs Gr B vs Gr C Equivalent Materials

SA285 Gr A Equivalent Materials

SA285 Gr A has the lowest strength, with tensile 45-65 ksi and yield 24 ksi. It is good for very low-pressure vessels.

Equivalents are chosen for similar low carbon and strength. The main one is ASTM A285 Grade A, which is the same.

Other equivalents:

• EU: EN 10028-2 P235GH, low carbon with yield 235 MPa.
• Germany: DIN 17155 HI, boiler steel with tensile 360-480 MPa.
• Japan: JIS G3115 SPV235, good for welding.
• UK: BS 1501 161-360A, same strength for tanks.
• China: GB 713 Q245R, heat-safe for low pressure.
• Korea: KS D 3560 SPV235, matches for vessels.
• France: AFNOR A37CP, like strength for welded tools.
• India: IS 2041 R220, boiler-grade with low strength.
• Australia: AS 1548-430R, for normalized tanks.

These work like SA285 Gr A for simple jobs. For , it is the same as Gr B.

SA285 Gr C Equivalent Materials

SA285 Gr C has the highest strength in the group, with tensile 55-75 ksi and yield 30 ksi. It is for medium-pressure vessels.

Equivalents have a bit more strength but similar low carbon. The main one is ASTM A285 Grade C.

Other equivalents:

• EU: EN 10028-2 P235GH or P265GH, tensile 360-480 MPa.
• Germany: DIN 17155 HI or HII, boiler-grade.
• Japan: JIS G3115 SPV235, yield 235 MPa.
• UK: BS 1501 161-360A, good for welding.
• China: GB 713 Q245R, heat-safe.
• Korea: KS D 3560 SPV235, matches strength.
• France: AFNOR A37CP, like for vessels.
• India: IS 2041 R220, low-strength boiler.
• Australia: AS 1548-430R, for pressure.

These match SA285 Gr C for low- to medium-pressure. For
