With the highest strength yield point minimum at 690 Mpa,A514 Grade H and A514 Grade J shall
be under Quenching and Tempering delivery condition when rolling.Comparing with these two
steel grades A514 Grade H and A514 Grade J,steel A514 Grade H contains more Ni and Cr
elements which can improve the property of rusty resistance when using.Such as the stainless
steel plates shall contains these two chemical elements.
When rolling,for the steel grain,all the steel shall be full killed and hot forming.Our
engineers suggest that for ordering steel plates A514 Grade H and A514 Grade J,our customers
had better list all their needed additional technical requirements.Because for these higher
steel grades,different customers would need different technicals owning to the different end
using application.These additional technicals normally contain SPWHT,UT and low temperature
impacting test.
