Quenched Tempered 65mn Steel Plate Manufacturer 40-55HRC Hardness 40mn Impact Spring Steel Plate 5mm Thickness Hot Rolled Metal Plate

Quenched Tempered 65Mn Steel Plate Manufacturer 40-55HRC Hardness 40Mn Impact Spring Steel Plate 5MM Thickness Hot Rolled Metal Plate Commonly used spring steel, the final heat treatment is quenching and tempering. This steel has high strength, high hardenability, and low decarburization tendency, but it is sensitive to overheating, prone to quenching cracks, and has tempering hardenability. In the annealed state, the cutting ability is good, the weldability is good, and the cold deformation plasticity is low. The strip can be generally bent and formed.
