201 stainless steel is a 200 series austenitic stainless steel developed by replacing nickel elements with manganese, nitrogen and other elements. It has good corrosion resistance and hot and cold working properties, which is enough to replace the previous use in indoor and inland cities. 304 stainless steel products used in low corrosive environments.

202 stainless steel plate is a metastable austenitic stainless steel. Its national standard model is 1Cr18Mn8Ni5N. It has high strength, toughness, high wear resistance and large work hardening. 202 stainless steel is widely used in architectural decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places. It is welded by high-precision automatic pipe-making equipment, through self-etching welding, rolling and forming, without any metal filler, filled with gas protection (inside and outside of the pipe) and welded. The welding method is TIG process, and online solid solution eddy current is used. flaw detection.

The yield strength of 2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more affordable than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy may also be considered, but there are some limitations, especially when applied to welded structures

304 stainless steel is a very common stainless steel, also known as 18/8 stainless steel in the industry. Its corrosion resistance is better than 430 stainless steel, with high corrosion resistance and good processing performance, so it is widely used in industry, furniture decoration industry and food and medical industry, such as: some high-grade stainless steel tableware, bathroom kitchen utensils.

It is used in field open-air machines in chemical, coal and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts of building materials and parts with difficult heat treatment.

After 304, SUS316 is the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as “marine steel”. SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level.

201 stainless steel, has a certain acid resistance, alkali resistance, high density, polishing no bubble, no pinhole and other characteristics, is the production of all kinds of watchcase, watchband bottom cover quality materials.
Mainly used for decorative pipe, industrial pipe, some shallow stretching products.

Most of the 304L stainless steel sheets are shipped in whole rolls, mainly for the convenience of transportation. In the hands of the stainless steel processing factory, in order to facilitate processing and manufacturing, these 304L stainless steel coils will be flattened by professional stainless steel flattening equipment, just like the whole roll of toilet paper, divided into pieces. The 304L stainless steel plate after opening is called “opening plate”.
