SA514 Grade K is for high yield strength, quenched and tempered alloy steel plate of structural quality in thickness of 50mm and under intended primarily for use in welded bridges and other structures.
The max thickness of SA514 Grade K is 50mm. in the heat treatment, SA514 Grade K shall be heat treatment by the mill to conform to the tensile and hardness requirements by heating to not less 900 degree and quenching in water or oil, tempering at not less 620 degree.
Gangsteel is the large agent in HBIS Wuyang mill and we have exported SA514 Grade K to be used in oil platform project.
