ASTM High yield strength steel plate A514 Grade K is used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements. Alloy steel plate A514GrK is normally used as a structural steel in building construction, cranes, or other large machines supporting high loads. Till now Katalor can offer the maximum thickness for high strength steel plate A514Gr.K reaching to 350 millimeters with heat treatment of quenched and tempered.
ASTM A514 standard specification for pressure vessel plates, carbon steel, for intermediate-and higher-temperature service
ASTM A514 grade K plates shall be normalized.
Thickness: 6MM to 300MM,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
