ASTM AH36 equivalent material

ASTM AH36 is high strength steel specially for shipbuilding and oil platform use. ASTM AH36 steel has high strength, good toughness, corrosion resistance, weldability, processing formability, and surface quality.

ASTM AH36 steel mechanical property:

Grade	Tensile Test			Impact Energy  KV2/J
	Yield Strength ReH/Mpa	Tensile Strength Rm/Mpa	Elongation A/%	Temperature	Longitudinal	Transverse
				℃
ASTM AH36	≥355	490-620	≥21	0	≥34	≥24

Q345B	345	470-630	20	20	34
A572 Gr.50	345	450	18	-	-
S355JR	355	470-630	22	20	27
ST52-3	355	490-630	22	0	27

Please note those materials are only close to ASTM AH36 steel in strength. In strict sense, they should not be regarded as absolute ASTM AH36 equivalent materials. Especially for marine use, the ASTM AH36 equivalent material is not recommended to use. ASTM AH36, the special shipbuilding steel would perform much better in such seawater corrosion environment.
