GB/T11251 1345 Alloy Structural Steel Plate Description

GB/T 11251 alloy structural steel plate  has high strength and wear resistance, high hardenability, moderate  cold deformation plasticity, good cutting performance and good welding  performance. During heat treatment, the toughness of steel decreases  less. GB/T 11251 alloy steel can still maintain high toughness under  water cooling conditions, but has the tendency of overheating  sensitivity, white point sensitivity and temper brittleness. They are  mostly used after quenching and tempering, and can also be used under  positive inflammation or hot rolling conditions. Typical  applications include valve bodies, pumps and fittings, wheels, bolts,  studs, gears, high loads on internal combustion engines. Drive shafts on  steel balls, rollers and bushings for electric locomotives, machine  tools, tractors, steel rolling equipment, boring machines, railway  vehicles and mining machinery, etc..
