Accreditation Administration System:
Under American standard ASTM A514/A514M,the steel plate A514 Grade B and A514 Grade A are
mainly used for building welded briges and other structures in high strength situiations.
A514 Grade B and A514 Grade A may be susceptible to reheat cracking in the heat affected
zone of welds during stress relief and simulated post welded heat treatment.The minimum
yield strength for steel A514 Grade B and A514 Grade A shall be above 690 Mpa,and the
tensile strength shall be from 760 to 895 Mpa.
Comparing with these two steel grades A514 Grade A and A514 Grade B,the A514 Grade B has
more contains of elements Vanadium and Titanium than steel Grade A514 Grade A.Else,both
these two steel grades have to do done Quenched and Tempered heat treatment when rolling.
Now we list the chemical elements analysis of ASTM A514 Grade B for your check,if you want
