302 stainless steel industrial pipe: 302 stainless steel rods are widely used in auto parts, aviation and aerospace hardware tools, chemical industry. Specific as follows: arts and crafts, bearings, sliding flower, medical equipment, electrical appliances, etc. Features: 302 stainless steel ball belongs to austenite shape steel, with close to 304, but the hardness is higher, 302 HRC 28 or less, has the good rust and corrosion
304 l stainless steel industrial pipe: as low carbon steel, 304 in the general case, corrosion resistance and 304 are similar, but after or eliminate stress after welding, the grain boundary corrosion resistance, excellent in without heat treatment, can also keep good corrosion resistance.
304 stainless steel industrial pipe: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, punching, bending, such as hot workability is good, no heat treatment hardening phenomenon. Purpose: tableware, ambry, boiler, auto parts, medical appliances, building materials, food industry (using the temperature - 196 ° C to 700 ° C)
310 stainless steel industrial pipe: the main features are: high temperature resistant, generally used in the boiler, the car's exhaust. Other performance in general.
303 stainless steel industrial pipe: by adding a small amount of sulfur and phosphorus to make it more 304 more machining, performance and other similar to 304.
302 stainless steel industrial pipe: 302 stainless steel rods are widely used in auto parts, aviation and aerospace hardware tools, chemical industry. Specific as follows: arts and crafts, bearings, sliding flower, medical equipment, electrical appliances, etc. Features: 302 stainless steel ball belongs to austenite shape steel, with close to 304, but the hardness is higher, 302 HRC 28 or less, has the good rust and corrosion
301 stainless steel industrial pipe: good ductility, used for forming products. Also can rapid hardening by mechanical processing. Good weldability. Abrasion resistance and fatigue strength is better than that of 304 stainless steel.
202 stainless steel industrial pipe: belongs to the chrome - nickel - manganese austenitic stainless steel, is better than 201 stainless steel
201 stainless steel industrial pipe: belongs to the chrome - nickel - manganese austenitic stainless steel, magnetic is low
410 stainless steel industrial pipe: belong to martensite chromium steel (high strength), good wear resistance, corrosion resistance is poor.
Grade 420 stainless steel industrial pipe, "cutters" martensitic steel, such as the brinell high chromium steel stainless steel at the earliest. Also used in surgical tools, can do is very light.
430 stainless steel industrial pipe: ferritic stainless steel, decoration, such as for car accessories. Good formability, but the temperature resistance and corrosion resistance to poor.
