S420M STEEL PLATE,EN10025-4 S420M
Source:Yusheng steel
Low alloy steel plate S420M with normal yield strength of 420Mpa,besides five main chemical elements,this steel
grade S420M also contains few alloy elements,such as Nb,Cr,Ni,Ti,Mo.These alloy approved the special property
for S420M steel.
For S420M steel plate in heavy thickness,our engineers still suggest done Normalized heat treatment for them if
customers want to improve their steel's property when using.Else,this steel must be done low temperature
impacting test at _20℃ with minimum energy 40J on longitudinal direction.
