11Cr-9Ni Austenitic Stainless (var. 2)
metalAn austenitic stainless steel containing approximately 11% chromium and 9% nickel, with molybdenum and titanium additions for enhanced corrosion resistance and strength. This variant sits in the lean-alloy range of austenitic stainless steels, designed to balance corrosion performance with cost efficiency compared to heavier nickel-bearing grades like 316L or 317. It is used in moderately corrosive environments where standard 304-grade austenitic steels would be insufficient but full duplex or super-austenitic alloys are economically or technically unnecessary—typical applications include chemical processing equipment, seawater-resistant fasteners and fittings, and heat exchanger tubes in mildly aggressive media.
