Product Description
WL Co-21 is recommended for applications involving cavitation, erosion, corrosion and/or high temperatures, such as valve trim for petrochemical and power generation. WLCo-21 has excellent resistance to thermal and mechanical shock. Optimum high temperature strength is obtained by solution heat treatments at 1200-1240ºC (2190 - 2265ºF) followed by quenching, and aging in the temperature range 700-1150°C (1290-2100°F). Due to its good impact resistance, it has been widely used in the building up of forging or hot stamping dies.
