ATI 201 HP is a 200-series, Cr-Mn-Ni austenitic stainless steel. It is comparable to the Cr-Ni stainless steel types 301, 304, and 304L in many respects, and can even provide some advantages over the 18-8 grades in certain applications. Because it possess a very desirable combination of economy plus good mechanical properties and corrosion resistance, it has been used in a wide variety of consumer and transportation applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1332. Producer or source: ATI.
