200 stainless steel pipe material-chromium-nickel-manganese austenitic stainless steel 300 stainless steel pipe material-chromium-nickel austenitic stainless steel 301 stainless steel pipe material-good ductility, used for molding products. It can also be hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.
302 stainless steel pipe material-Corrosion resistance is the same as 304, because the carbon content is relatively high, so the strength is better.
303 stainless steel pipe material-It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304 stainless steel tube material-18/8 stainless steel. GB grade is 0Cr18Ni9. 309 stainless steel pipe material-better temperature resistance than 304.
316 stainless steel pipe material-After 304, the second most widely used steel type, mainly used in the food industry, pharmaceutical industry and surgical equipment, the addition of molybdenum element to obtain a special structure resistant to corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as “marine steel”. SS316 is usually used in nuclear fuel recovery equipment. 18/10 grade stainless steel usually also meets this application level.
Stainless steel bucket Model 321 stainless steel pipe material-similar to 304 except that the addition of titanium reduces the risk of corrosion of the material weld.
400 stainless steel pipe material-ferritic and martensitic stainless steel 408 stainless steel pipe material-good heat resistance,
weak corrosion resistance, 11% Cr, 8% Ni.
409 stainless steel pipe material-the cheapest model (Anglo-American), usually usedas automobile exhaust pipe, is a ferritic stainless steel (chrome steel).
410 stainless steel pipe material-martensite (high strength chrome steel), good wear resistance, poor corrosion resistance. 416 stainless steel pipe material-added sulfur
improves the material's processing performance.
420 stainless steel pipe material-"blade grade" martensitic steel, similar to the earliest stainless steel of Brinell high chromium steel. Also used in surgical knives, it can be made very bright. 430 stainless steel
tube material-ferritic stainless steel, for decoration, such as used in car accessories. Good moldability, but poor temperature
resistance and corrosion resistance.
440 stainless steel pipe material-high-strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain higher yield strength, hardness can reach 58HRC, belongs to the hardest stainless steel.
The most common application example is the "razor blade". There are three commonly used models: 440A, 440B, 440C, and 440F
(easy to process).
500 stainless steel pipe material-heat-resistant chromium alloy steel.
600 stainless steel pipe material-Martensitic precipitation hardening stainless steel.
Stainless steel 630 stainless steel pipe material-the most commonly used precipitation hardening stainless steel model, usually also called 17-4; 17% Cr, 4% Ni.
