AISI 4140 Steel Mechanical Properties. Material 4140 mechanical properties are given in the table below. Steel. Tensile strength, Mpa (ksi) Yield strength, Mpa (ksi) Elongation in 50 mm (2 in), %. Reduction in area, %. Hardness (HB) Sample diameter.
Tempering. 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 ...

SAE-AISI 4140 steel is an alloy steel formulated for primary forming into wrought products. 4140 is the designation in both the SAE and AISI systems for this material. G41400 is the UNS number. It can have a moderately high tensile strength among the SAE-AISI wrought steels in the database. The properties of SAE-AISI 4140 steel include four ...
The elements improve the mechanical properties of the steel, such as strength, toughness, and wear resistance. Also referred to as SAE 4140, this steel grade has high hardenability, which means it can be heat treated to achieve high strength and hardness levels. AISI 4140 steel is a popular low-alloy steel that contains chromium,
AISI 4140 is a low alloy steel. Low alloy steels rely on elements besides 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. The additions of chromium and molybdenum are why AISI 4140 is considered a “chromoly ...
