ASME SA 36 / ASTM A36 steel is very widely used mild steel material on the globle market. It also has various equivalent steel grades in other countries, such as GB Q235B, JIS Ss400, EN S235JR, DIN ST37-2. In India, there is also a local mild steel grades, IS 2062. Is ASME SA 36 equivalent to IS 2062 steel?
It needs to be analized from chemical composition and mechanical properties of ASME SA 36 steel and IS 2062 steel:
(1) Chemical composition of ASME SA 36 steel and IS 2062 steel: %
| Grade | C (t≤16mm) | Si | Mn | P | S | N |
| ASME SA 36 | 0.26 max | 0.40 max | - | 0.040 max | 0.050 max | - |
| IS 2062 | max 0.23 | 0.40 max | 1.5 max | 0.045 max | 0.045 max | 0.012 max |
(2) Mechanical properties of ASME SA 36 steel and IS 2062 steel:
| Grade | Yield strength ReH/(N/mm2) | Tensile strength Rm/(N/mm2) | Elongation A/% |
| (t≤16mm) min | (3mm≤t≤16mm) | (3mm≤t≤40mm) min | |
| ASME SA 36 | 250 Mpa | 400-500 | 20 |
| IS 2062 | 250 Mpa | 410Mpa min | 23 |
The chemical composition of IS 2062 steel is equivalent to that of ASME SA 36 steel. And the mechanical properties of IS 2062 steel almost can match that of ASME SA 36 steel also. Therefore, ASME SA 36 equivalent to IS 2062 steel.
