Factory direct supply high quality metal Galvanized Stainless Steel Welded Pipe

Classification

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

200 Series - Chromium-Nickel-Manganese Austenitic Stainless Steels

300 Series - Chromium-Nickel Austenitic Stainless Steels

301—Good ductility, used for molded products. Machine speed hardening is also possible. 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—By adding a small amount of sulfur and phosphorus to make it more machining.

304—that is, 18/8 stainless steel. The GB grade is 06Cr19Ni10.

309—has better temperature resistance than 304.

316—After 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, adding molybdenum to obtain a special structure that is resistant to corrosion. Because of its better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18/10 stainless steels generally also meet this application level. [1]

Model 321—Similar to 304 except that the risk of corrosion in material welds is reduced due to the addition of titanium.
