1. Key Properties
Ç. 72100 is a high-carbon, chromium-alloyed steel primarily used for bearing applications. Known for its excellent wear resistance, toughness, and high hardness, this steel is engineered to perform in high-stress environments. The alloy's chemical composition, including chromium, provides superior hardenability and resistance to corrosion, making it ideal for components subjected to heavy loads, friction, and high wear. The round bar form ensures ease of machining and precision, making it perfect for high-performance bearing components that demand tight tolerances and high dimensional accuracy.
