Cleveland-Cliffs 11 Cr-Cb is a ferritic stainless steel that has increased silicon levels and is dual stabilized with titanium and niobium. It provides elevated temperature strength and oxidation resistance superior to that of type 409 and comparable to those of 18 Cr-Cb and type 439 stainless steels. This alloy should be considered for applications in which type 409 stainless steel provides only marginal strength and oxidation resistance. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-1343. Producer or source: Cleveland-Cliffs Inc.
