4142 and 4142 alloys are used in various industrial applications.
Thus, the primary alloying elements are chromium and molybdenum. As a result, 4140 is used in applications that require high wear resistance and high temperatures. Meanwhile, 4142 alloys are used in various industrial applications, including tools and other types of equipment. After heat treatment, it is a medium carbon chromium-molybdenum alloy steel with high strength and toughness.
O’Hare Precision Metals can provide a wide range of company-supplied or customer-supplied components and materials. Just like how we can offer you the best 4140/4142 Alloys bar stocks and 4140/4142 Alloys round bar stocks in O’Hare!
4140 has a machinability rating of 66 percent, which is excellent. However, the presence of molybdenum contributes to the uniformity of hardness and high strength. Also, it is a complicated metal to weld, but it is possible if the section is preheated before welding and then stress relieved after welding.
4142 Alloy Steel is a through-hardening alloy steel with high strength and toughness after heat treatment. It possesses excellent fatigue and impact resistance. Alloy steels with tensile and yield strengths in 4140/4142 are available. The machinability of steel increases as it is hardened and tempered.
Axles, shafts, tools bodies, tie rods, stubs, couplings, reamers, gears, racks are the common applications of 4140/4142 Alloys.
