Dec 18, 2019 · AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F). AISI 4140 Alloy Steel - Quality Products & Best PricesMechanical Properties of 4140 Steel AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. AISI AISI 4140 H SAE J 1268 - BBN STEEL STORESAISI AISI 4140 H SAE J 1268 physical. Physical performance parameters of AISI AISI 4140 H SAE J 1268 are mainly indicated by density, poisson's ratio, thermal conductivity, specific thermal capacity, coefficient of thermal expansion, modulus of elasticity, electrical resistance value, etc. Temperature.
Characterization of the mechanical properties of the AISI/SAE 4140 steel when applying the plasma nitriding process and making the respective analysis was established with the tests of Rockwell hardness, wear resistance and tension.
