How many stainless steel materials are there?

Stainless steel materials are as follows:

Model 301- Good ductility for molding products. It can also be quickly hardened by mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.

Model 302- Corrosion resistance is the same as 304, with better strength due to relatively higher carbon content.

Model 303- Easier to machined than 304 by adding a small amount of sulfur and phosphorus.

Model 304- General model; So 18/8 stainless steel. The GB brand is 0Cr18Ni9.

Model 309- has better temperature resistance than 304.

Model 316- the second most widely used steel after the 304, used in the food industry and surgical equipment, has molybdenum added to give it a special structure that is resistant to corrosion. It is also used as "Marine steel" because of its better resistance to chloride corrosion than 304. SS316 is usually used in nuclear fuel reprocessing units. Grade 18/10 stainless steel is also usually qualified for this application class
