This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, extrusions, flash welded rings, and stock for forging, extruding, or flash welded rings. These products have been used typically for parts requiring high strength and corrosion resistance from -425 to 1100 degrees F (-254 to 593 degrees C) and where parts may require welding during fabrication, but usage is not limited to such applications.
