APPLICATIONS
These products have been used typically for parts on which the amount of machining warrants the use of a free-machining grade of steel requriing corrosion resistance similar to the 18-8 type steel, and which will be subjected to high temperatures during facrication or in service.
This specification is a free-machining, corrosion and heat-resistant steel in the form of bars, wire, forgings, and forging stock.
