About 321 stainless steel
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.
201 stainless steel plate
About 201 /202 stainless steel
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.
316/316L stainless steel plate
316/316L stainless steel
About 316 material:316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions.Corrosion resistance is better than 304 stainless steel, in pulp and paper production process has good corrosion resistance. And 316 stainless steel is also resistant to erosion of marine and corrosive industrial atmosphere.
About 316L material: 316L stainless steel has a carbon content of less than 316, which is commonly used in pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal areas outside the building materials. Corrosion resistance is better than 316 material.
304/34L stainless steel plate
304/304Lstainless steel
304 304L belongs to austenitic stainless steel, it is the most widely used in the 300 series materials. On the whole, the 304 304L has very similar characteristics, the only difference lies in the level of carbon content, so there will be a little difference more or less in the application filed, but the overall application is the same.
304L has lower carbon content and better corrosion resistance. But 304 of the strength is higher than 304L, so 304 has a higher strength than 304L.From the application: 304 can be widely used in various departments, various fields. 304L is mainly used in welding and other fields.
