JIS G3101 SS400 equivalent ASTM

There are a lot of JIS G3101 SS400 equivalent grades in the steel market. Among them, JIS G3101 SS400 equivalent ASTM is ASTM A36 steel and ASTM A283C steel. The JIS G3101 SS400 steel and JIS G3101 SS400 equivalent ASTM have similar chemical and property and can be used in stead of each other in most conditions.

BBN steel would like to make a comparison among JIS G3101 SS400 steel and JIS G3101 SS400 equivalent ASTM A36 steel and ASTM A283C steel.

JIS G3101 SS400 steel and JIS G3101 SS400 equivalent ASTM A36 steel and ASTM A283C steel chemical composition %:

Grade C  (t≤16mm) Si Mn P S Cu
SS400 - - - 0.050 max 0.050 max -
A36 0.26 max 0.40 max - 0.040 max 0.050 max 0.20 min
A283C 0.24 max 0.04 max 0.09 max 0.035 max 0.040 max 0.20 min

JIS G3101 SS400 steel and JIS G3101 SS400 equivalent ASTM A36 steel and ASTM A283C steel mechanical properties:
