ASTM A514 Steel Plates Material Properties
ASTM A514 Steel Plates Material Properties
A514GrQ/F is a high-strength weldable steel plate quenched and tempered under ASTM standards. I know that it is used in places requiring high tensile strength and high yield. Racks used for engineering automobile lifting gears, large diggers and offshore platforms are generally A514Gr.Q or A514Gr.Q modified, which vary in thickness. Its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is above 700MPa. The product is domestic and international, ending the long-term dependence on imports of steel plate A514GrQ/F for China's offshore oil platform. Physical quality meets or exceeds ASTM-A514 standards. Available for ABS and CCS certification.
