321 stainless steel plate belongs to the American standard titanium austenitic stainless steel, the implementation of the standard: ASTM A240/A240M-19
The performance of 321 stainless steel is very similar to 304, but due to the addition of titanium metal, it has better grain boundary corrosion resistance and high temperature strength. The formation of chromium carbide can be well controlled by adding titanium.
321 stainless steel industry application:
Used in grain boundary corrosion resistance of high chemical, coal, oil industry outdoor machinery, building materials heat-resistant parts and parts with difficulty in heat treatment
1. Oil waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler enclosure, heat exchanger, heating furnace parts
4. Muffler parts for diesel engines
5. Boiler pressure vessel
6. Chemical tanker
7. Expansion joint
8. Spiral welded pipes for furnace and dryer
316 is austenitic stainless steel, ASTM A240/A240M-19
316 stainless steel because of the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is better, can be used in harsh conditions; Excellent work hardening (non-magnetic); Excellent high temperature strength, mainly used in seawater equipment, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD bars, bolts, nuts.
