AISI 4145H Chemical Composition

The Chemical Composition of AISI 4145H contains a medium level of the carbon content of 0.42-0.49 %. The material has an Mn content of 0.65-1.10 % which imparts hardness to the material. The contents of P is reduced to 0.035% and S is reduced to 0.040 % max as excess content of P and S can damage the quality of steel and can cause the alloys steel to break at low stresses. The SAE 4145H has Ni and Mo content along with Cu.

AISI 4145H APPLICATION

As AISI 4145H offers a high degree of hardness, it is used in the manufacture of high-hardness machine parts. The SAE 4145H material, for instance, is used in the manufacture of nuts and bolts, screws, machine arms, pistons, shafts, axles, and crankshafts, etc. In areas, such as oil drilling, aviation, and shipbuilding, where corrosion is a serious problem, SAE 4145H provides good corrosion resistance. apAs SAE 4145H is one of the alloy steel grades of steel, it also possesses high tensile strength. High-temperature heat treatment is possible with SAE 4145H.
