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. See also Alloy Digest SS-368, October 1979.

CARPENTER STAINLESS TYPE 304HN is essentially a high-nitrogen version of AISI Type 304 stainless steel. By means of solid-solution strengthening, the nitrogen provides significantly higher yield strength and tensile strength as annealed than conventional Type 304, without adversely affecting ductility, corrosion resistance or nonmagnetic properties. Its applications include aircraft and aerospace components and marine hardware. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-368. Producer or source: Carpenter.
