AISI 4140 Alloy Steel is chromium, molybdenum, and manganese containing low alloy steel. It has high fatigue strength, toughness, abrasion resistance, and torsional strength. AISI 4140 is 1% chromium – molybdenum medium harden the capability basic cause excessive tensile metal.
AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913°C (1675°F) for a long period of time, followed by air cooling. Forging. AISI 4140 alloy steel is forged at 926 to 1205°C (1700 to 2200°F) Hot Working
Alloy Steel 4140 - Continental Steel & Tube Company
Alloy Steel 4140, also sold under the name AISI/SAE 4140, is a low alloy steel that contains chromium, molybdenum, and manganese. Known for its impact and abrasion resistance, Alloy Steel 4140 also offers users outstanding fatigue and torsional strength. Welding is possible through most popular techniques, and it has a high level of ductility.
The alloy can be hardened by heat treatment. Typical applications for 4140 low alloy steel include structural use such as aircraft engine mounts and welded tubing applications. AISI 4140 Alloy Steel (UNS G41400) Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels.
