The property of 321 stainless steel and 347 stainless steel is similar in most cases, the 321 stainless steel is a kind of titanium – stabilization of 18/8 austenitic stainless steel (304), a small amount of titanium makes it in carbide precipitation temperature range, that's 425-850℃, not appear intergranular corrosion after heating, with good strength, …
Stainless Steel 347 - Alloy Composition. Stainless Steel 347 has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. Alloy 347 is a columbium (niobium)/tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular

Type 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. This type of grades are thus recommended for parts fabricated by welding which cannot be subsequently annealed
Type 347 is an austenitic stainless steel stabilized by additions of columbium (plus tantalum) to reduce or prevent carbide precipitation during welding and in service at 800/1650ºF (430/900ºC.) The columbium addition also improves high temperature properties. The grade has good resistance to corrosion and oxidation and good creep strength.
Ultrasonic shot peening (USP) is a relatively new process of surface modification to improve mechanical properties as well as corrosion and high-temperature oxidation resistance of metallic materials. The effect of USP on surface properties and the process of high-temperature oxidation in air and steam environment, following USP of the …
