GB/T11251 1345 Alloy Structural Steel Plate


GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steel plates. GB/T 11251 Hot rolled plate has high strength and wear resistance, high hardenability, moderate cold deformation plasticity, good cutting performance and good welding performance. During the heat treatment, the toughness of the steel decreases less. GB/T 11251 alloy steel can still maintain high toughness under water cooling conditions, but it has a tendency of overheating sensitivity, white spot sensitivity and temper brittleness.
