ASME SA285 Gr A vs Gr B vs Gr C Equivalent Materials

ASME SA285 Gr A vs Gr B vs Gr C Equivalent Materials

If you work with pressure vessels or boilers, knowing the equivalent materials for SA285 Gr A, Gr B, and Gr C is helpful for finding cheaper or local options.

SA285 is a low-carbon steel under the asme sa 285/sa 285m standard, used for low-pressure tanks.

The grades A, B, and C have more strength as the letter goes up. At Gangsteel, we make and sell SA285 plates from China.

This guide shows equivalents for each grade, with tables to compare. For the full astm a285/a285m steel plate range, which is like SA285, check our stock. You can find asme sa 285 grade a for low strength, asme sa 285 grade b for medium, or asme sa 285 grade c for higher.

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 astm a 285 grade a, it is the same as Gr A.

ASME SA285 Gr B Equivalent Materials

SA285 Gr B has medium strength, with tensile 50-70 ksi and yield 27 ksi. It is for a bit higher pressure than Gr A.

Equivalents have similar mix and strength. The main one is ASTM A285 Grade B.

Other equivalents:

• EU: EN 10028-2 P265GH, yield 265 MPa for hot vessels.
• Germany: DIN 17155 HII, tensile 410-530 MPa for boilers.
• Japan: JIS G3115 SPV315, good for pressure.
• UK: BS 1501 161-430A, matches for welded tanks.
• China: GB 713 Q275R, low-pressure heat-safe.
• Korea: KS D 3560 SPV315, good stretch.
• France: AFNOR A42CP, same strength.
• India: IS 2041 R260, for boilers.
• Australia: AS 1548-430R, as-rolled or heated.

These are good for medium-pressure jobs like SA285 Gr B. For astm a 285 grade b, 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 astm a 285 grade c, it is the same as Gr C.

Comparison of ASME SA285 Gr A, Gr B, and Gr C Equivalents

The equivalents for Gr A are for very low strength, Gr B for medium, and Gr C for a bit higher. They all have low carbon for easy weld and are used in similar low-pressure jobs.
