Alloy Steel AISI 52100 is a high-carbon chromium alloy steel, known for its outstanding hardness, wear resistance, and fatigue strength. Its composition includes high carbon and chromium content, which enables excellent rolling-contact fatigue properties and superior toughness when heat treated. The steel offers high tensile strength and excellent dimensional stability, making it ideal for precision components. While it has limited weldability due to its carbon content, AISI 52100 can be machined and ground to exact specifications after appropriate heat treatment, providing reliability in high-load and high-wear applications.
