ALL BELOW GRADES can be supplied in SHEET, MASTER & SLIT COIL, BAR, BLANKS and FABRICATED to various components.

409

(Chromium content 10.50 min, 11.70 max.) A stabilized FERRITIC stainless steel widely used where oxidation and corrosion protection needs to exceed that of carbon and some carbon coated steels. Available in Hot Rolled Annealed and Pickled #1 (HRAP) and Cold Rolled 2B or 2D surface finishes. End users include manufacturers of Automotive, Power Generation, Agricultural, Woodstove and Casket components. Gauges range from .006″ to 1.00″.Data Bulletin

439

(Chromium content 17.0 min, 19.O max.) A stabilized FERRITIC stainless steel with a higher Chromium content than T409 which offers improved corrosion resistance. Available in Cold Rolled 2B or 2D surface finishes. End users include manufacturers of Automotive Exhaust components. Gauges range from .015, to .187. 439 is available in dual-stabilized or titanium-only stabilized versions of which either version performs equally in all environments.Data Bulletin
