Pyrowear® 53

UNS #K71040

Pyrowear® 53 is a premium quality carburizing gear steel with a combination of high-temperature performance, fatigue resistance, deep hardenability, and excellent toughness. The alloy has a resisted softening at elevated service temperatures and possess good temper resistance and high case hot hardness while maintaining high core impact strength and fracture toughness. It is double vacuum processed by vacuum induction melting followed by vacuum arc remelting (VIM-VAR) to provide optimum metallurgical quality.
