AISI321 Stainless Steel Coil Thickness 0.6 - 16.0mm 2B NO.1 Surface SS Coil Strip Roll
321 Stainless Steel Coil
321 stainless steel coil is a free-machining austenitic chromium-nickel austenitic alloy (18% Cr, 12% Ni) that provides good corrosion resistance in a wide range of corrosive environments.
321 stainless steel coils are widely used in the chemical and petrochemical industries where its corrosion resistance properties can be put to good use. The alloy also finds application in marine environments where chloride stress corrosion cracking must be avoided. It is also used for food processing equipment such as food blenders and mixers, beverage dispensing equipment and heat exchangers.

What are 321 stainless steel coils?
321 stainless steel coil is a type of austenitic stainless steel with low carbon content and good corrosion resistance to many corrosive environments. 321 offers excellent weldability, good machinability and outstanding fabrication properties.
321 stainless steel coil is commonly used in the chemical industry, pulp and paper industry, marine and offshore engineering industries as well as in the food and beverage industries.
321 stainless steel coil also has a high level of resistance to chloride stress corrosion cracking and pitting. It is also resistant to hydrochloric acid at elevated temperatures up to 250°C (480°F).
What are the applications that 321 stainless steel coils can be used?
1. Petroleum waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler shell, heat exchanger, heating furnace parts
4. Silencer parts for diesel engines
5. Boiler pressure vessel
6. Chemical transport truck
7. Expansion joint
8. Spiral welded pipes for furnace and dryers
Features of 321 stainless steel coils
- Good Corrosion Resistance: 321 stainless steel coil has better corrosion resistance than 304 and 316 types of stainless steels, which makes it ideal for use in corrosive environments.
- Excellent Weldability: 321 stainless steel coil can be welded by all methods including arc welding ( TIG / GTAW ), electron beam welding ( EBW / EFW ), submerged arc welding ( SAW ) and laser beam welding ( LBIW ).
- High Strength: The strength levels of 321 stainless steel coils are up to 50% higher than those of 304 types of stainless steels and up to 80% higher than those of 316 types of stainless steels due to their increased carbon content and austenite grain size.
What is the standard sea packaging of 321 stainless steel coil?
- Standard export sea packaging:
Waterproof Paper Winding+PVC Film+Strap Banding+Wooden Pallet or Wooden Case; - Customized packaging as your request (Logo or other contents accepted to be printed on the packaging);
- Other special packaging will be designed as customer’s request;
Eye to wall and eye to sky are both available; - By International Express: DHL/UPS/FEDEX/EMS and our own express line;
