The titanium within means the stainless steel is intergranular corrosion resistant after heating, (between 425-900 degrees Celsius). Remarkably high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades. 321 Stainless Steel Seamless Pipe321 Stainless Steel Corrosion Resistance of 321 Stainless Steel Seamless Pipes and Tubes. Equivalent to Grade 304 in the annealed condition and superior if a weldment in these grades has not been post-weld annealed or if the application involves service in the 425-9000C range.

AISI 321 Stainless Steel Stainless Steel Special Alloy 321Stainless 321 / AISI 321 Stainless 321 is a chromium-nickel steel which was developed with improved intergranular-corrosion resistance. Stainless 321 is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals.
ASTM A213 TP 321 seamless tube is made from stainless steel billet, after cold drawn and cold rolling, heat treatment should be made in specific temperate, finished seamless tubes are mainly applied for boiler, heat exchanger, super heater system. ASTM A213 Specification. 321 Stainless Steel Grade ASTM A213 TP 321 Seamless Stainless Steel TubeASTM A213 TP 321 seamless tube is made from stainless steel billet, after cold drawn and cold rolling, heat treatment should be made in specific temperate, finished seamless tubes are mainly applied for boiler, heat exchanger, super heater system. ASTM A213 Specification. 321 Stainless Steel Grade ASTM A312 / A312M - 19 Standard Specification for Seamless Note 1:When the impact test criterion for a low-temperature service would be 15 ft·lbf [20 J] energy absorption or 15 mils [0.38 mm] lateral expansion, some of the austenitic stainless steel grades covered by this specification are accepted by certain pressure vessel or piping codes without the necessity of making the actual test. For example, Grades TP304, TP304L, and TP347 are accepted by
Difference Between 304 304L and 321. 304 stainless steel is low carbon chromium nickel stainless and heat resisting steel somewhat superior to Type 302 in corrosion resistance.. 321 stainless steel is known as stabilized grades of stainless steel, is Chromium nickel steel containing titanium. Recommended for parts fabricated by welding which cannot be subsequently annealed. Precision tubes custom-made to the highest qualitySuperior Tube manufacture high precision tubing products in stainless steel, nickel, titanium and zirconium alloys, seamless or welded in straight or coils. Small Diameter Stainless Steel Tubing - 304, 316, 321 Stainless Steel, Aluminum & Brass Alloy Selections. 304 / 304 L:The most common 300 stainless series alloy, good corrosion resistance, cold working characteristics and relative cost effectiveness make this our most popular alloy. The "L" grade version has a lower carbon content for reduced carbide precipitation during secondary welding operations.
Oct 23, 2001 · Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by ium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C. Stainless Steel Grades (The Ultimate Guide) MachineMfgSS316 is usually used for nuclear fuel recovery devices. Grade 18/10 stainless steel is also usually in this application level. 321 stainless steel. In addition to the risk of the corrosion of the weld joint is reduced because of adding the titanium element, the other performance is similar to 304 stainless steel. 400 series stainless steel Stainless Steel Manufacturers & Suppliers - China Material Grade :304 316 304l 316l 309s 310s 321 stainless steel plate /stainless steel sheet Technique :hot rolled cold rolled Surface :No .1 Thickness :3mm-60mm Width :1000mm,1200mm,1220mm ,1250mm,1500mm,2000mm and customized Length :2000mm--2500mm customized Additional Service :cutting punching
