AISI 4145H material properties are high tensile strength, stress resistance, wear and tear resistance, and hardness. AISI 4145H offers good wear and tear resistance in quenched and tempered conditions. AISI 4145H equivalent grade is SAE 4145H. AISI 4145H hardness is more as compared to other steel grades. AISI 4145H finds its application in industries such as the aircraft industry, automobile industry, automotive industry, defence industry, etc. AISI 4145H is a special grade with more hardness than AISI 4145. Heat Treatments such as normalizing, tempering, quenching, etc can be applied to AISI 4145H. It is used to make chains, screws, gears, arms, rollers and various other machine parts.
National Steel Industries is the most prominent supplier of AISI 4145H steel. Buy good quality AISI 4145H round bar and AISI 4145H sheets from us which are tested for a variety of parameters and delivered with a material test certificate for complete quality assurance.
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.
