St52-3

St52-3 steel plate, under DIN17100 standard, we can regard St52-3 steel plate as Carbon and low alloy steel.St52-3 steel plate is one mainly of Carbon and low alloy steel, equal to DIN17100:St52-3,JIS:SS490/SM490A,BS:50B and UNI7070:Fe510B.

Common structural steel for welded assemblies,Re>355 N/mm2. Guaranteed toughness at 0℃. It can be used for statically and dynamically stressed constructions.

As for the Heat Treatment, soft annealing heat to 650-700℃,cool slowly; harden from a temperature of 860-890℃ followed by oil or water quenching; tempering,normalizing temperature 860-890℃;forging, hot forming temperature 1050-850℃;machinability is good,rated at 90% that of the 1112 alloy used as a 100% maching rated steel.
