Description / Abstract:
Form
This specification covers two types of corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.
Application
These products have been used typically for parts requiring resistance to both corrosion and wear with hardness up to 58 HRC, where the amount of machining warrants use of a free-machining steel, but usage is not limited to such applications.
Classification
The steel compositions covered by this specification are classified as follows:
Type 1 - 17Cr - 0.50Mo - 0.22S (0.95 - 1.20C)
Type 2 - 17Cr - 0.50Mo - 0.20Se (0.95 - 1.20C)
Unless a specific type is ordered, either Type I or Type II may be supplied.
