Forging DIN 1.7225 Steel Processing Technology Forging DIN 1.7225 Steel

1.Forging DIN 1.7225 Steel Product
4140 steel is a kind of alloy structural steel. It belongs to the steel with
the American grade equivalent to the 42CrMo 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 0.33%-0.48%, its tensile
strength is 795 MPa, and its hardness is 241HB. After heat treatment at 4140,
it has good strength and good comprehensive mechanical properties, and it has
good manufacturability. Fasteners, salvage tools,etc.

3.Forging DIN 1.7225 Steel Application:
It is used to manufacture forgings that require higher strength and larger
quenched and tempered section than 35CrMo 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 2000m, and can be used for
molds of bending machines,etc.
