Product Description
Q420B SEV295 S420ML/1.8836 Carbon Steel Plate
1: Q420B Steel Introduction
Q420B steel plate has good mechanical properties and welding properties, with yield strength above 420MPa and tensile strength above 500MPa. It has high elongation, usually above 18%, and shows good plasticity and toughness. In the rolling process, better surface quality and dimensional accuracy can be obtained by controlling the parameters of heating, rolling and cooling.
