ASTM AH36 VS A36 steel plate in chemical composition and mechanical properties

When it comes to A36 steel plate, it has 2 understanding. One is ASTM A36/ A36M mild steel plate. The other is ASTM A131 A36 shipbuilding steel plate, same as AH36 steel for this understanding. Today, we would like to make a distinguish between ASTM AH36 shipbuilding steel plate and A36 mild steel plate, the first understanding for A36 steel plate. We will make ASTM AH36 VS A36 steel plate in chemical composition and mechanical properties.

ASTM AH36 VS A36 steel plate in chemical composition:

Grade C Mn P S Si Al Cb V Ti Cu Cr Ni Mo
ASTM AH36 0.12-0.20 0.30-0.70 ≦0.045 ≦0.045 ≦0.30 ≧0.015 0.02-0.05 0.05-0.10 ≦0.02 ≦0.35 ≦0.20 ≦0.40 ≦0.08
ASTM A36 ≦0.18 0.70-1.60 ≦0.035 ≦0.035 0.10-0.50                

ASTM AH36 VS A36 steel plate in mechanical properties:

Grade Yield strength Tensile strength Extension
MPA MPA %
ASTM AH36 ≧355 490~620 ≧22
ASTM A36 ≧250 400~550 ≧20

For the first understanding of A36 steel plate, ASTM A36/ A36M mild steel plate. It is totally different from ASTM A131 AH36 shipbuilding steel plate. A36 steel plate is mild steel with common strength, while  AH36 steel plate is high strength shipbuilding steel, supplied with certificate of classification societies.
