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.
304/304L stainless steel sheet
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.
201 stainless steel sheet
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.
309/309S stainless steel sheet
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.
