316 stainless steel is the most widely used chromium nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (service temperature -196 ℃ ~ 800 ℃). It is corrosion-resistant in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability.

201 is a kind of stainless steel. 201 stainless steel generally refers to 201 stainless steel and acid resistant steel. 201 stainless steel refers to the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.This product 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.

304 stainless steel is the most widely used chromium nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (service temperature -196 ℃ ~ 800 ℃). It is corrosion-resistant in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability.

Grade 409 is a titanium-stabilised ferritic stainless steel. Although regarded as a general-purpose chromium stainless steel the almost exclusive application for Grade 409 is automotive exhaust systems. Its applications are those where appearance is a secondary consideration to mechanical properties and corrosion resistance, particularly at high temperatures, and where some weldability is required.

Grade 430 is a ferritic, straight chromium,non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim, indoor panelling such as refrigeration cabinets and appliance components are its largest fields of application.This grade is only readily available in sheet and coil (up to 1.2mm thick), most commonly in BA or 2B finishes, or polished to No4. The BA finish sheet has a quite bright, reflective appearance.

439 stainless steel reduces the content of C on the basis of ordinary ferritic material (430) and adds stabilizing elements such as Ti to improve the intergranular corrosion resistance, formability and weldability of the steel. Compared with 304 steel, although the elongation is low (about 30%), the strength and corrosion resistance are equivalent, and the corrosion resistance is better than 200 series materials. Chromium content is 12% ~ 30%. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than that of stainless steel.

Grade 904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids,particularly sulphuric acid. It is also highly resistant to chloride attack - both pitting / crevice corrosion and stress corrosion cracking.This grade is non magnetic in all conditions and has excellent weldability and formability.The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
