304L stainless steel, also known as ultra-low carbon stainless steel, is a kind of universal stainless steel material, widely used in the production of equipment and parts requiring good comprehensive properties (corrosion resistance and formability).

201 stainless steel is composed primarily of iron with between 16 and 18% chromium and up to 0.15% carbon. It also contains small amounts of manganese, nickel, silicon, nitrogen, and copper. It has higher formability than the 300 series grades. In addition, it can be hardened by cold working processes but not heat-treated like 304 or 316 grades. 201 is a high manganese and low nickel stainless steel with low nickel content and poor corrosion resistance. It is widely used in various tabletops, countertops, kitchenware, outdoor decoration engineering, urban decoration industry and low-grade household products. It is also used in medical instruments and automotive parts that require flexibility while maintaining strength under pressure.

202 stainless steel is an austenitic chromium-nickel-manganese alloy. It has high ductility, good corrosion resistance and excellent toughness in both high and low temperature environments. 202 stainless steel is one of the most widely used 200 series stainless steel. 202 stainless steel, the austenitic structure is stabilized by the addition of nickel and manganese, thereby preventing the formation of harmful phases, such as sigma phase or chromium carbide. The high nickel content also improves the corrosion and oxidation resistance of the steel at high temperatures.

The 301 stainless steel belt is a kind of metastable austenitic stainless steel with complete austenitic structure under the condition of sufficient solution.
In stainless steel, 301 is the most easily cold deformation strengthening steel grade, through the cold deformation processing can make the strength of steel, hardness, and retain enough plastic and toughness, together with the steel under the condition of the atmosphere with good rust resistance, but the poor corrosion resistance, reducing medium in acid and alkali salt chemical medium corrosion resistance is poorer, therefore is not recommended for corrosion harsh environment.

Hot-rolled stainless steel plate is a leading-edge material, which features the strong points of stainless steel and carbon steel. Like high strength, corrosion resistance, oxidation resistance, wear resistance, and acid-base resistance; with 50 years of service life; low carbon steel price; ensure its good strength, toughness.

904L stainless steel is a high-strength material. This high-strength characteristic allows 904L stainless steel to maintain stable performance when subjected to high loads and stresses, and is not prone to deformation and fracture. It also has good toughness and can maintain good toughness in low temperature environments. More importantly, 904L stainless steel also has good wear resistance and can maintain good durability and stability in friction and wear environments. This characteristic allows 904L stainless steel to maintain a long service life under various mechanical movements and friction situations. Lastly, 904L stainless steel plate has excellent corrosion resistance and can maintain stable performance in various corrosive environments.

309 stainless steel is an austenitic stainless steel containing higher chromium and nickel content. 309 stainless steel has excellent corrosion resistance in various corrosive media, including acid, alkali, salt and other solutions, as well as organic solvents.

This makes it advantageous in some applications requiring high temperature processing.

Stainless 431 offers the best corrosion resistance of the conventional martensitic stainless grades. Stainless 431 has the best corrosion resistance to marine atmospheres, also resists attack by many petroleum products and organic materials, and several acidic environments.

Duplex Stainless Steel (Duplex Stainless Steel, referred to as DSS), refers to ferrite and austenite each accounted for about 50%, generally less phase content also needs to reach at least 30% of stainless steel. In the case of low C, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements.

Stainless steel disc mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal structure, and the main role is chromium. Chromium has high chemical stability and can form a passivation film on the steel surface to isolate the metal from the outside world, protect the steel plate from being oxidized, and increase the corrosion resistance of the steel plate.

The perforated plate is formerly known as the punching plate, which is the plate obtained by punching holes on the plate of different materials. Different metal plates are cut to fit and perforated on a CNC press.
