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.

Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly blunt edges. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked thin plates. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a structural part of a house frame and an escalator in a building.
