316 stainless steel bar :316 stainless steel contains molybdenum and low carbon, in the Marine and chemical industry environment of the pitting corrosion ability is much better than 304 stainless steel! (316L low carbon, 316N high nitrogen high strength, 316 stainless steel sulfur content is high, easy to cut stainless steel).

304L stainless steel bar: As low carbon 304 steel, in general, corrosion resistance is similar to 316L, but after welding or stress removal, its resistance to grain boundary corrosion is excellent, without heat treatment, can also maintain good corrosion resistance.

316 stainless steel bar: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping, bending and other thermal processing, no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (operating temperature -196°C-700°C).

310 stainless steel bar: the main characteristics are: high temperature resistance, generally used in the boiler, automobile exhaust pipe. Other performance is average.

310S stainless steel bar: Is austenitic chrome-nickel stainless steel with good oxidation resistance, corrosion resistance, because of the higher percentage of chromium and nickel, 310S has much better creep strength, can continue to operate at high temperatures, has good high temperature resistance.

303 stainless steel bar: it is easier to machined than 304 by adding a small amount of sulfur and phosphorus, and other properties are similar to 304.

Stainless steel bar: stainless steel bar is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. Specific as follows: crafts, bearings, sliding flowers, medical instruments, electrical appliances and so on.

301 stainless steel bar: good ductility for molding products. It can also be quickly hardened by mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.

202 stainless steel bar: chromium - nickel - manganese austenitic stainless steel, better performance than 201 stainless steel.

201 stainless steel bar: chromium - nickel - manganese austenitic stainless steel, low magnetic.

410 stainless steel bar: martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.

420 Stainless steel bar :" edge grade "martensitic steel, similar to brinell high chromium steel, the earliest stainless steel. Also used for surgical knives, which can be made very bright.

317 stainless steel bar: pitting resistance is better than 316 steel. Used as material for printing and dyeing equipment.

430 stainless steel bar: ferritic stainless steel, for decorative purposes, e.g. automotive accessories. Good formability, but poor temperature and corrosion resistance.

302 stainless steel ball belongs to austenitic steel, and 304 is close to, but 302 hardness is higher, HRC≤28, has good rust and corrosion resistance.
