Equivalent grades map common carbon and alloy steel grades across IS, ASME (ASTM), DIN, and EN standards.

What are the equivalent structural carbon steel grades across standards?

IS 2062 E250 is roughly equivalent to ASTM A36. EN 10025 S235JR is ASTM A284. Always check the Yield requirement (210 MPa for E250).

IS 2062: Fe 410

ASTM: A36, A283

EN: S235, S275

  • IS 2062 E250 ~= ASTM A36
  • IS 2062 E410 ~= ASTM A572 Gr 60
  • E250 YR (Yield >= 250 MPa)

Which alloy steel pipe grades are equivalent across IS, ASTM, and DIN?

ASME A335 P11 (1.25Cr-0.5Mo) is roughly equivalent to DIN 13CrMo44 (WB36). P22 (2.25Cr-1Mo) is similar to 10CrMo910.

P11: 1.25Cr-0.5Mo

P22: 2.25Cr-1Mo

Mapping: Always check the Yield/Tensile curve.

  • A335 P11 ~= DIN 13CrMo44
  • A335 P22 ~= 10CrMo910
  • P5: 5Cr-0.5Mo (~15Mo3)
