    Bearing steel is often referred to as SAE 52100 Alloy steel. SAE 52100 Alloy steel has a high carbon, chromium content. A low alloy steel, SAE 52100 Alloy steel is particularly suitable for bearing applications due to its good hardness.

    One of the major beneficiaries of the SAE 52100 Alloy steel is the airline industry, which uses this alloy to manufacture bearings and other highly stressed components. These AISI / SAE 52100 Rods feature high wear resistance, heat resistance, and superior hardness and rolling fatigue strength. The SAE 52100 Alloy steel is a cost-effective solution with extended working life that can be used continuously at temperatures up to 120°C. In terms of Rockwell hardness, SAE 52100 Alloy steel has a hardness value of 60 – 67 Rc at room temperature. 

    In order to optimise SAE 52100 Alloy steel’s performance, it is preferably remelted using a vacuum arc technique. While AISI 52100 Bright Bars can be hardened by cold and hot working processes, they can also be annealed and tempered. Heat treatment could strengthen both annealing and tempering SAE 52100 Alloy steel. Because of its combination of tensile strength, hardness, and workability, SAE 52100 Alloy steel is useful for mill rolls, and vehicle parts.SAE 52100 Alloy steel is used in bearings in rotating machinery. SAE 52100 is also used to manufacture anti-friction bearings. Micro Metals supplies AISI 52100 round bar, steel flat bar, hexagonal bar, and steel square block. Alloy steel SAE 52100 can be supplied in any length you require. The chemical composition of the substance includes Si (0.15-0.35), C (0.98 – 1.10), Cr (1.30-1.60),Mn (0.25-0.45). SAE 52100 steel can be hot worked at 205 to 538°C (400 to 1000°F). Aisi 52100 Steel Rod is forged at 927 to 1205°C (1700 to 2200°F).
