15CrMo 20CrMo steel plate  

15CrMo 20CrMo steel plate 15CrMo steel plate is a kind of alloy structural steel, belongs to the pearlite structure heat-resistant steel. 15CrMo steel plate has high strength at temperatures lower than 500-550 ℃, good workability and ductility under cold deformation and acceptable weldability (preheating up to 300 ℃ before welding and heat treatment after welding). 15CrMo steel plate is commonly used in normalising and high temperature tempering. 20CrMo steel plate is generally used in quenched or carburised condition. 20CrMo alloy steel plates are generally used in the quenched, tempered or carburised condition. 20CrMo steels are used in the production of high-pressure piping and a variety of fasteners, as well as more advanced carburised parts such as gears and shafts, which operate in a non-corrosive environment, at temperatures lower than 250°C, and contain mixtures of nitrogen and hydrogen. 15CrMo steel plate Chemical composition (%) : &…
