Stainless steel seamless pipe is a long steel material with a hollow section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the processing cost will increase significantly.
Stainless steel pipes can be divided into Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series) and precipitation hardening series (600 series) according to their composition.
200 Series-Chromium-Nickel-Manganese Austenitic Stainless Steel 300 Series-Chromium-Nickel Austenitic Stainless Steel.
1.
301-----Good ductility, used for molded products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
2.
302-----The corrosion resistance is the same as that of 304, but the strength is better due to the relatively higher carbon content.
3.
303-----By adding a small amount of sulfur and phosphorus, it is easier to cut than 304.
4.
304-----18/8 stainless steel. The GB grade is 0Cr18Ni9. 309-has better temperature resistance than 304.
5.
316-----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 gives it a special corrosion-resistant structure.
