product Heat-Treated Steels Alloy and Free-Cutting Steels-Ball and Roller Bearing Steels
certification BIS ISI Certification
Standard IS 17111:2019 (ISO 683-17:2014)
description Heat-treated steels, including alloy and free-cutting steels, are essential materials used in the manufacturing of ball and roller-bearing steels due to their superior mechanical properties. These steels undergo specialized heat treatment processes to enhance their strength, hardness, and wear resistance, making them ideal for bearing applications where reliability and durability are paramount. Alloy steels are alloyed with elements such as chromium, molybdenum, and nickel to improve their mechanical properties, while free-cutting steels contain additives like sulfur and lead to enhance machinability. The heat treatment process involves heating the steel to specific temperatures and then rapidly cooling it to achieve the desired microstructures and properties. The resulting heat-treated steels exhibit excellent fatigue resistance, load-carrying capacity, and dimensional stability, ensuring smooth operation and prolonged service life of ball and roller bearings in various industrial applications, including automotive, aerospace, machinery, and manufacturing.
