Overview
The CF8C austenitic stainless steel is a popular alloy for applications where extensive welding is to be done without subsequent heat treatment and for extended service at elevated temperatures in the 900° to 1200° F range. It has good machining and welding characteristics and is slightly magnetic. It provides great wear and galling resistance along with good toughness.
Typical Uses
Bearings, pump and valve components, chemical and food processing equipment, heat exchangers, pulp/paper applications, aircraft shroud assemblies, turbine engine parts, and marine fittings.
