Stainless
Stainless E-Brite (tm)
Annealing Procedure
Soak at 1400-1750 F(760-945 C), rapid cool.
Applications
The alloy has been successfully used in a variety of components in the food, oil producing, chemical, petrochemical, and paper pulp industries.
Formability
Due to its high chromium content, this alloy will not exhibit the same degree of uniform deformation associated with the austenitic stainless steels. Its high level of ductility and low work hardening rate allow successful forming using most common methods.
Hardening Procedure
This alloy does not respond to hardening by heat treatment.
Machinability
This alloy can be machined by all common techniques. It is similar in characteristic to 304/ 304L stainless. Heavy feeds and slow speeds are recommended. The material has a relatively low work hardening rate but will produce long "gummy" chips. The use of chip curlers and breakers is desirable.
Principle Design Features
This alloy is a ferritic stainless steel, combining high purity, corrosion resistance and good fabricability.
Weldability
GTAW and SMAW are the preferred welding methods with this material. Common filler metals include stainless types 310 and 312 as well as nickel alloy G. Selection of filler material should take into consideration the final application and requirements for strength, ductility and corrosive environment.
