ATI 302

Abstract

ATI 302 (UNS S30200) is a variation of the 18Cr-8Ni austenitic alloy, the most familiar and most frequently used stainless steel. This alloy may be considered for a wide variety of applications where one or more of the following properties are important: resistance to corrosion, prevention of product contamination, ease of fabrication, attractive surface, ease of cleaning, or good strength and oughness at cryogenic temperatures. Past users of ATI 302 are generally now using ATI 304 because argon oxygen decarburizationtechnology has made lower carbon levels more easily attainable and economical. ATI 302 may be preferred over ATI 304 for temper rolled products or in other instances where its higher carbon content enables it to meet certain yield strength and tensile strength requirements while maintaining a higher level of ductility (elongation) versus that of the lower carbon ATI 304. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fatigue. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-1360. Producer or source: ATI.
