Application and specification of 321 stainless steel pipe

Application and specification of 321 stainless steel pipe
Mirror finish 321 stainless steel tube is widely used in medical applications
321 stainless steel tube chemical composition: carbon: 0.08 silicon: 1.00 manganese: 2.00 phosphorus: 0.045 sulfur: 0.030 nickel: 9.00-12.00 chromium: 17.00-19.00 titanium: 5C-0.70
Austenitic 321 stainless steel is equivalent to domestically produced 1Cr18Ni11Ti
Japanese trademark: SUS321
UK trademarks: 304S12, 321920
German trademark: X10CrNiTi189
US trademark: 321 S32100、TP321
321 stainless steel pipe is a Ni Cr Mo austenitic stainless steel pipe, which has similar properties to 304 stainless steel pipe. However, due to the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium metal, it effectively manipulates the composition of chromium carbide.
321 stainless steel pipe has excellent high-temperature stress rupture performance and high-temperature creep resistance, and its stress mechanical properties are superior to 304 stainless steel pipe.
Professional application:
Used for outdoor machines in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, as well as for heat-resistant building materials and parts that are difficult to heat treat
1 . Petroleum waste gas combustion pipeline
2 . Engine exhaust pipe
3 . Boiler shell, heat exchanger, heating furnace components
4 . Silencing components for diesel engines
5 . Boiler pressure vessel
6 . Chemical transport vehicle
7 . flexible joint
8 . Spiral welded pipes for furnace pipelines and dryers
