321 has better resistance to intergranular corrosion than most of the standard 300 grades other than the low carbon types 304L, 316L and 317L due to its titanium content.N.B. It is most important that oxygen is always allowed to circulate freely on all stainless steel surfaces to ensure that a chrome oxide film is always present to protect it. 321 Stainless Steel - Dongshang Stainless321 Stainless Steel. ium as the stable elements exist in 321 stainless steel, it is variation of 304 stainless steel, 321 stainless steel in different temperature and different concentration of organic acid and inorganic acid, especially has good wear and corrosion resistance in oxidizing medium for the manufacture of the wear resistant acid containers and equipment lining, pipeline.
321 STAINLESS STEEL TYPE 321 is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 1500 °F (427 816 °C) service. It also improves the elevated temperature 321 Stainless Steel Brown McFarlane321/ 321H Stainless Steel Plate. A 300 series stainless steel less sensitive and more suited to elevated temperature environments (up to 900°C) when compared against the more standard austenitic grades (304/316). 321/321H has increased resistance to scaling and intergranular corrosion (versus 304/316 material) due mainly to its added titanium content. 321 Stainless Steel Plate, Sheet, Round Bar, Pipes, Tubes 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.
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. 321 Stainless Steel Sheet - Slice of StainlessType Grade AMS ASTM Finish Density; Sheet/Plate:321:5510:A240, A480:2D:0.286 321 Stainless Steel Sheet - Slice of StainlessType Grade AMS ASTM Finish Density; Sheet/Plate:321:5510:A240, A480:2D:0.286
While Type 321 continues to be employed for prolonged service in th4e 800 to 1500° F (427 to 816° C) temperature range, Type 304L has supplanted this stabilized grade for applications involving only welding or short time heating. Type 321 stainless steel s also advantageous for high temperature service because of its good mechanical properties. 321 Stainless Steel Technical Data Sheet - metal shimsWhile Type 321 continues to be employed for prolonged service in th4e 800 to 1500° F (427 to 816° C) temperature range, Type 304L has supplanted this stabilized grade for applications involving only welding or short time heating. Type 321 stainless steel s also advantageous for high temperature service because of its good mechanical properties. AISI 321 Stainless Steel Stainless Steel Special Alloy 321Stainless 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.
Alloy 321 (UNS S32100) is stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C).Alloy 321 stainless steelis stabilized against chromium carbide formation by the addition of titanium. Recommended speeds for cutting stainless aisi 321May 09, 2016 · The closest thing to it will be the austenitic stainless steels, which is a broad range. The specs also tend to be geared towards forged and/or annealed bar. 321 is more difficult than 316SS. It's been quite a while since I've turned 321. To put in in to perspective here are some relative numbers for 316 compared to 321 Stainless Steel Type 321 Rolled Metal Products Type 321 is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500F temperature range where it is stabilized against chromium carbide precipitation by the addition of titanium, which results in the precipitation of titanium carbides.
321 stainless steel (1.4541) is a heat resistant grade utilised by a wide variety of industries. We stock Grade 321 in a number of different products and sections and provide numerous machining, processing and finishing services for 321, all with a fast turnaround. Overview The key and differentiating property of grade 321 is the  Type 321 Stainless Steel 321 Stainless Smiths Metal Type 321 stainless steel is a variation of grade 304 with the addition of titanium as a stabiliser. The alloy is resistant to intergranular corrosion and can be easily welded and/or formed. Technical Assistance Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Grade 321 Stainless Steel - Universal Stainless321 is an austenitic stainless steel that is melted as AOD melt type. This is a stabalized version of 304 stainless to help improve intergranular corrosion resistance. This alloy is similar to 347 stainless except uses titanium to stabilize the carbon instead of niobium. The improved corrosion resistance allows this grade to be used in service at much higher temperatures close to 1000 o F.
