According to the composition, it can be divided into Cr (SUS400), Cr-Ni (SUS300), Cr-Mn-Ni (SUS200) and precipitated hardening system (SUS600).

200 series - chromium - nickel - manganese austenitic stainless steel

300 series - chromium - nickel austenitic stainless steel

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

302 - corrosion resistance is similar to 304, with better strength due to higher carbon content.

303 -- By adding a small amount of sulfur and phosphorus to make it more processed.

304 -- 18/8 stainless steel.GB brand number is 06CR19NI10.

309 -- Better temperature resistance than 304.

316 -- The second most widely used steel after 304, mainly used in the food industry and in surgical equipment, is added molybdenum to give it a special corrosion resistant structure.It is also used as "Marine steel" because it has better resistance to chloride corrosion than 304.SS316 is commonly used in nuclear fuel recovery plants.Class 18/10 stainless steels are usually qualified for this application.[1]

Model 321 -- similar in performance to the 304 except that the risk of weld corrosion of the material is reduced due to the addition of titanium.

400 series - ferritic and martensitic stainless steels

408 -- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.

409 -- The cheapest model (UK and US), commonly used as a car exhaust pipe, of ferritic stainless steel (chrome steel).

410 -- martensite (high strength chrome steel), good wear resistance, poor corrosion resistance.

416 -- The addition of sulfur improves the processability of the material.

420 -- "tool grade" martensitic steel, similar to the earliest stainless steels of Brinell high chromium steel.It's also used for surgical cutlery, which can be made very bright.

430 -- Ferritic stainless steel, decorative, e.g. for automotive accessories.Good formability, but poor temperature resistance and corrosion resistance.

440 -- high strength cutting steel, slightly higher carbon content, after proper heat treatment can obtain a high yield strength, hardness up to 58HRC, is among the hardest stainless steels.The most common example of an application is the "razor blade".There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process).

500 series - heat resistant chromium alloy steel.

600 series - martensite precipitated hardened stainless steel.

630 -- The most commonly used precipitation hardened stainless steel model, also commonly known as 17-4;4% 17% Cr, Ni.
