The high chromium content makes it resistant to corrosion in a wide range of environments such as wet chlorine, hydrochloric acid and nitric acid. For maximum ductility, fabricated components should be annealed 2150-2250°F followed by a rapid cooling.
Our common stock sizes from .250” to 2.50” diameters.
Common Specifications:
Heat treatment: Bars shall be solution heat treated by heating to a temperature within the range 2150 to 2250 °F, holding at the selected temperature within ±25 °F for a time commensurate with section thickness, and cooling at a rate equivalent to an air cool or faster.
Hardness of bars 277 HB max.
