Stainless steel industrial pipe
Stainless steel industrial pipe is divided into: 304L stainless steel industrial pipe, 304 stainless steel industrial pipe, 310 stainless steel industrial pipe, 303 stainless steel industrial pipe, 302 stainless steel industrial pipe, 301 stainless steel industrial pipe, 202 stainless steel industrial pipe, 201 stainless steel industrial pipe, 410 stainless steel industrial pipe , 420 stainless steel industrial pipe, 430 stainless steel industrial pipe, etc.
304L stainless steel industrial pipe: As a low-carbon 304 steel, in general, the corrosion resistance is similar to 304, but after welding or stress relief, its resistance to grain boundary corrosion is excellent. It can also be used without heat treatment. Maintain good corrosion resistance.
304 stainless steel industrial pipe: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping, bending, and no heat treatment and hardening. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (using temperature -196 ° C-700 ° C)
The main features of 310 stainless steel industrial pipes are: high temperature resistance, generally used in boilers, automotive exhaust pipes, and other general performance.
303 stainless steel industrial pipe: It is easier to cut and process than 304 by adding a small amount of sulfur and phosphorus. Other properties are similar to 304.
302 stainless steel industrial pipe: 302 stainless steel rods are widely used in auto parts, aviation, aerospace hardware tools, and chemical industry. The details are as follows: crafts, bearings, slides, medical instruments, electrical appliances, etc. Characteristics: 302 stainless steel ball is austenitic steel, which is closer to 304, but the hardness of 302 is higher, HRC≤28, and it has good rust and corrosion resistance.
301 stainless steel industrial pipe: good ductility, used for forming products. It can also be hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.
202 stainless steel industrial tube: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel.
201 stainless steel industrial pipe: belongs to chrome-nickel-manganese austenitic stainless steel, and its magnetic property is relatively low.
410 stainless steel industrial pipe: belongs to martensite (high-strength chrome steel), has good wear resistance and poor corrosion resistance.
420 stainless steel industrial pipe: “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 industrial pipe: ferritic stainless steel, for decoration, such as for car accessories. Good moldability, but poor temperature resistance and corrosion resistance
