316L Stainless steel black rod due to the addition of Mo, 316L stainless steel has excellent corrosion resistance, especially pitting corrosion resistance; High temperature strength is also very good; Excellent work hardening (weak magnetism after processing); The solid solution state is non-magnetic.

321 Stainless steel black rod exhibits high strength, resistance to oxidation peeling and subsequent stability against aqueous solution corrosion in a temperature range up to approximately 900 degrees Celsius. 321 Stainless steel black rod also has excellent forming and welding characteristics, can be bent or roll pressed forming, no annealing after welding. It has excellent toughness even at low temperatures.

304L Stainless steel black rod mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure, and chromium plays a major role. Chromium has high chemical stability, which can form passivation film in cold rolled plate, isolate stainless steel from the outside world, protect cold rolled plate from oxidation, and increase the corrosion resistance of cold rolled plate. After the passivation film is damaged, the corrosion resistance decreases.

304 Stainless steel black rod is one of the most popular stainless steel cold rolled sheet products.304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel is the most widely used stainless steel, heat resistant steel. Used in food production equipment, general chemical equipment, nuclear energy, etc.

301 Stainless steel black rod 301(17Cr-7Ni-carbon) material: compared with 304 steel, Cr, Ni content is less, the tensile strength and hardness increase during cold working, non-magnetic, but magnetic after cold working. Use: train, aircraft, conveyor belt, vehicle, bolt, spring, screen.

202 Stainless steel black rod has strong corrosion resistance and can resist the corrosion of most acid and alkali media; The price is moderate, more economical and practical; Good processability, welding, cutting, stamping and so on.

201 Stainless steel black rod with polishing no bubbles, no pinholes and other characteristics, is the production of a variety of watchcase, watchband cover quality materials. 201 Stainless steel gloss bar is mainly used in high temperature applications, high temperature applications require the material to have strong resistance to sensitization to prevent interparticle corrosion at lower temperatures.

904L Stainless steel Irregular tube super austenitic stainless steel is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosion conditions. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking has high resistance, not easy to appear corrosion spots and cracks, pitting corrosion resistance is slightly better than other steel types, with good processability and weldability, can be used in pressure vessels.

444 Stainless steel Irregular tube，444 (00Cr18Mo2) is an ultra-low carbon nitrogen, containing 18% chromium and 2% molybdenum, high corrosion resistance of ferritic stainless steel. The yield strength of 444 is equivalent to 1.5 times that of carbon steel and 6 times that of FRP. It has outstanding advantages in earthquake resistance, snow resistance, wind pressure resistance and impact resistance. SUS444 ferritic stainless steel has high thermal conductivity, about 130% ~ 150% of chromium-nickel austenitic stainless steel, which is very suitable for heat exchange purposes.
