SAE 52100 is a high-carbon chromium alloy steel that mainly consists of about 1.00% carbon, 1.50% chromium, along with trace amounts of manganese, silicon, and sulfur. It’s well-known for its impressive hardness, tensile strength, and outstanding fatigue resistance, particularly after undergoing heat treatment. Typically, SAE 52100 reaches a tensile strength of around 850–1000 MPa and boasts a hardness of up to 60–67 HRC. This steel shows minimal distortion during hardening and maintains excellent dimensional stability, making it perfect for precision components like bearings and other load-bearing parts that operate under high-stress conditions.
