How about stainless steel grades?

How about stainless steel grades?

Answer:

According to the composition can be divided into Cr (400 Series), Cr Ni system (300 Series), Cr Mn Ni (200 Series) and the precipitation hardening systems (Series 600). 200 series - chromium nickel manganese austenitic stainless steel 300 series - chromium nickel austenitic stainless steel 301 - ductility, used for molding products. It can also be hardened rapidly by mechanical processing. Good weldability. The abrasion resistance and fatigue strength are better than 304 stainless steel. 302 - 304 with corrosion resistance, due to the relatively high carbon intensity. 303 - by adding a small amount of sulfur and phosphorus, it is easier to cut than 304.

304 - that is, 18/8 stainless steel. GB is 0Cr18Ni9. 309 - better temperature resistance than 304. 316 - after 304, second of the most widely used steel grades are used mainly in the food, pharmaceutical and pharmaceutical industries, and molybdenum is added to obtain a special corrosion resistant structure. Because of its better resistance to chloride corrosion than 304, it is also used as "ship steel". SS316 is usually used in nuclear fuel recovery devices. Grade 18/10 stainless steel usually meets this application level. [
