1020 steel round bar is widely used in medium and heavy machinery industry, such as forging or suppression of rod, shackle, leverage. 1020 belongs to high quality low carbon steel, cold extrusion, carburizing and hardening steel.
ABS FH32 steel can achieve the impact toughness at Celsius degree -60°. The ABS FH 32 grade steel plates have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa).
GB/T1591 Q345A I beam /angle/ channel steel decreases the yield value as the thickness of the material increases. And may be less than 345, so when the mechanical design strength must be less than the value of 345, otherwise there will be problems.
