321 stainless steel belongs to austenitic stainless steel, its performance is very similar to the 304, but due to the addition of the metal titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium, making it effective control of the formation of chromium carbide.
Excellent high-temperature stress of 321 stainless steel with a breaking (Stress Rupture) properties and high temperature creep resistance (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.

Applications
321 stainless steel is a high grade stainless steel in the 300 series, because the nickel content is relatively high. The utility model is applied to the outdoor machine of chemical, coal and petroleum industry with high grain boundary corrosion resistance, heat resistant parts of building materials and difficult parts of heat treatment, such as:
oil waste gas pipeline,engine exhaust pipe,boiler shell, heat exchanger, heating furnace parts,Noise components of 4 diesel engine,boiler pressure vessel,chemical transport vehicles,expansion joint,Spiral welded pipe for furnace pipe and dryer.
More about for the product of stainless steel-Twenty rolling machine
20 roller mill, which comprises a frame, roller, roller box, pressing device, driving device, which is characterized as a rectangular frame of high-quality steel casting the whole frame arch, arch and roll box for sliding window with the upper and lower body roll box, and the box with the backing bearing rectangular saddle connecting rectangular saddle and the roller box locking device, the roller box is provided with a swinging cylinder, including swing arm, connecting rod, double wedge wedge adjusting mechanism between the upper support roller A, C, B and D are respectively provided with a camber control device comprises a hydraulic cylinder, rack and gear piece. The adopted roll system can produce cold rolled strip products required by the market. This new type 20 roller mill frame has reasonable structure, high stiffness, shape control effect is good, the production of strip thickness precision can reach 0.001mm, rectangular saddle and arch processing is convenient, with high precision, lower roll box convenient, can make the rolling line to maintain the standard height.
304/304Lstainless steel coil
201 stainless steel is the most widely used in the 200 series. Because 201 stainless steel With"acid"and "alkali resistance"and"high density", "no bubbles", "no pinhole, polishing". 201 is the choice of all kinds of "watchcase", "watchband bottom”,"decorative tubes", "industrial tubes", and a plurality of products with shallow drawing etc. Compared with 201 grade,the only difference with 201 is that the Nickle contenting,and with the same applications,characteristic etc.
Stainless Steel Strip
Stainless steel strip is simply an extension of an ultra thin stainless steel plate. A narrow and long steel plate produced mainly in order to meet the needs of industrial production of various metals or mechanical products in different industrial sectors.Actually,stainless steel is produced by stainless steel coil.Usually use the slitting machine to process it into strip,with the same usage with stainless steel coil.
309/309S stainless steel coil
309/309S stainless steel
309S is cutting stainless steel containing sulfur, the main requirements for cutting and surface finish high occasions. Widely used in important areas boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, furnaces, chemical, petrochemical, and other.
The only difference is that 309 stainless steel does not contain sulfur, and now basically produce steel 309S material. Both can be summed up as the same material.,have the same purpose.To some extent, the carbon content of 309S is lower than 309.
