西安 Stainless steel rod 2 series:

202 stainless steel bar: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel.

201 stainless steel bar: It belongs to chromium-nickel-manganese austenitic stainless steel, and its magnetic properties are relatively low.

3 series:

316L stainless steel bar: 316 stainless steel contains molybdenum and low carbon content, and the pitting corrosion resistance in the ocean and the chemical industry environment is much better than 304 stainless steel! (316L low carbon, 316N nitrogen and high strength, high sulphur content in 316F stainless steel, easy to cut stainless steel.

304L stainless steel bar: 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 bar: 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).

310 stainless steel bar: The main features are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are general.

303 stainless steel bar: By adding a small amount of sulfur and phosphorus to make it easier to cut and process than 304, other properties are similar to 304.

302 stainless steel bar: 302 stainless steel bar is 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 bar: good ductility, used for molded products. It can also be hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.

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.

西安 Stainless steel rod 4 series:

408—Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.

409—The cheapest model (British and American), usually used as car exhaust pipe, is a ferritic stainless steel (chrome steel).

410 stainless steel bar: belongs to martensite (high-strength chrome steel), has good wear resistance and poor corrosion resistance.

416—The addition of sulfur improves the processability of the material.

420 stainless steel bar: "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 bar: Ferritic stainless steel, for decoration, for example, for car accessories. Good moldability, but poor temperature resistance and corrosion resistance.

440—High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, it can obtain higher yield strength and hardness can reach 58HRC, which is among the hardest stainless steels. The most common application example is the "razor blade". There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process).
