The stainless steel tube can be classified into a Cr system (400 series), a Cr-Ni system (300 series), a Cr-Mn-Ni (200 series), and a precipitation hardening system (600 series). 200 series - chrome-nickel-manganese austenitic stainless steel, 300 series - chrome-nickel austenitic stainless steel.

301-----extension is good for molding products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.

302-----corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.

303-----It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.

304-----that is 18/8 stainless steel. The GB grade is 0Cr18Ni9. 309 - Better temperature resistance than 304.

316-----After 304, the second most widely used steel grade, mainly used in the food industry, the pharmaceutical industry and surgical equipment, added molybdenum to obtain a special structure resistant to corrosion.

321 - Other properties are similar to 304 except that the addition of titanium reduces the risk of corrosion of the material weld.

400 series - ferritic and martensitic stainless steel.

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

409—The cheapest model, usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).

410—Martensite (high-strength chrome steel) with good wear resistance and poor corrosion resistance.

416—The addition of sulfur improves the processing properties of the material.
