Carpenter Stainless Type 304HN is the high-nitrogen version of Type 304 and 304H stainless steels. Interstitial strengthening with both carbon and nitrogen provides this alloy with significantly higher yield and tensile strength as annealed. Typical applications include aerospace and power components, as well as marine shafting. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-763. Producer or source: Carpenter.
