Product Description

 Steel Product Information

1.Describe:
***0 steel is a kind of alloy structural steel. It belongs to the steel with the American grade equivalent to the *2CrMo grade in my country. This kind of steel belongs to the medium hardenability steel with high yield, good comprehensive mechanical properties, good strength, good toughness and hardenability. High advantages, its carbon content is 0.*3%*0.*8%, its tensile strength is **5 MPa, and its hardness is **1HB. After heat treatment at ***0, it has good strength and good comprehensive mechanical properties, and it has good manufacturability. Fasteners, salvage tools, etc.

2.Corresponding steel number:
China GB steel number *2CrMo, Germany DIN steel number *2CrMo4, Germany DIN material number 1.***5, French NF standard *0CD4/*2CD4, Japanese JIS standard SCM**0, British BS standard **8M*0/**8A*2/**9M*0, American AISI/ASTM ***0, American SAE ***0, American UNS Standard G****0
(***0 alloy structural steel, executive standard: ASTM A*9/A*9M**4)

3.Application:
It is used to manufacture forgings that require higher strength and larger quenched and tempered section than *5CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below ***0m, and can be used for molds of bending machines, etc.

4.Feature:
This steel has good strength, good toughness, high hardenability, good workability, small processing deformation, quite good fatigue resistance, small deformation during quenching, and high creep strength and durable strength at high temperature.
