ASTM A572 grade 50 VS A36 carbon steel plate

For ASTM A572 grade 50 and A36 carbon steel plate. When ASTM A572 grade 50 VS A36 carbon steel plate in chemical composition, other than other elements differences, ASTM A572 grade 50 is also called A572 grade 50 carbon steel plate by some users considering its carbon content. ASTM A36 steel is popular carbon steel plate.

ASTM A572 grade 50 VS A36 carbon steel plate in chemical composition:

Item C Mn P S Si Cu
A572 grade 50 ≦0.26 ≦1.65 ≦0.040 ≦0.050 ≦0.40  -
A36 ≦0.26 - ≦0.040 ≦0.050 ≦0.40 ≧0.20

But when ASTM A572 grade 50 VS A36 carbon steel plate in mechanical properties, they have obvious differences. A36 carbon steel plate is general strength steel, while ASTM A572 grade 50  steel is high strength steel.

ASTM A572 grade 50 VS A36 carbon steel plate in mechanical properties:

Item Yield strength ReH/(N/mm2)
(t≤16mm) min
Tensile strength Rm/(N/mm2)
(3mm≤t≤16mm)
Elongation A/%
(3mm≤t≤40mm) min
A572 grade 50 345 450 18
A36 250 400-550 23

The yield and tensile properties for A36 carbon steel plate are 36 ksi and 58-80 ksi. The yield and tensile properties for ASTM A572 grade 50 steel are 50 ksi and 65 ksi. So the mechanical properties for ASTM A572 grade 50 steel meets and/or exceeds that of A36 carbon steel plate.
