Stainless steel materials:

TypeGradeFeaturesUse
Austenitic304Good corrosion resistance, heat resistance, excellent mechanical properties, no magnetic.Construction engineering, decoration and decoration, chemistry, food industry, medicine, fiber industry, auto parts, etc.
304L304 stainless steel low carbon steel, both 304 stainless steel characteristics; Due to low carbon content, excellent intergranular corrosion resistance and good weldability.Chemical, coal, petroleum, atomic energy and other fields requiring corrosion resistance; Heat-resistant parts and mechanical components that cannot be heat treated after welding.
304J1Non-magnetic, nickel content is lower than 304 steel, with cost advantage; The addition of copper Cu, has good molding performance; The mechanical strength and corrosion resistance are similar to 304 steel.With excellent molding and welding properties, it can be widely used in kitchen utensils, household appliances, architectural decoration and other fields. It is a new multi-functional material.
316Due to the addition of Mo Mo, its corrosion resistance, high temperature strength is particularly excellent, non-magnetic.As a steel with good corrosion resistance, suitable for food, paper, dye, oxalic acid and fertilizer production equipment, and widely used in petrochemical, nuclear reactors, coastal facilities and other fields.
316L316 low carbon steel, excellent intergranular corrosion resistance, can be used in more demanding corrosion conditions.Because of its excellent intergranular corrosion resistance, it is widely used in the environment of many corrosion factors, and also used to manufacture mechanical components which are relatively harsh and cannot be heat treated after forming.
321Non-magnetic, added Ti Ti, excellent intergranular corrosion resistance, good weldability; Excellent corrosion resistance in oxidizing acid; It also has good corrosion resistance in alkali liquor, most organic and inorganic acids, atmosphere and water vapor.Because of its excellent intergranular corrosion resistance, it is widely used in construction engineering, chemical equipment and other fields, such as aircraft, seamless steel pipe, boiler bubble, pressure vessel and some welded, combined parts can not be heat treated.
310SIs a high chromium Cr, high nickel Ni high alloy stainless steel, non-magnetic; It has excellent plasticity and welding performance, high temperature strength, good corrosion resistance, and can be used under the condition of high temperature, strength, corrosion resistance and oxidation resistance.Because of its excellent performance, it is widely used in chemical equipment, heat-resistant parts and other fields, typical use for annealing box, drying equipment, industrial furnace lining, heat exchanger, oil refining equipment and so on.
Ferrite430There are magnetic; Low thermal expansion rate, good thermal conductivity, good molding and oxidation resistance; Do not add nickel, molybdenum and other precious metals, has a cost advantage; With proper processing (e.g. brilliant annealing, mirror finish), excellent surface appearance can be obtained.Because of its economic, corrosion resistance, good formability and other characteristics, it is widely used in construction engineering (outer wall, pillar, window frame, stairs, etc.), kitchen utensils (washing pool, gas station, operating table, utensils, pans, etc.), computer parts, automobile decoration and other fields.
409LLow carbon C, low nitrogen N, add Ti Ti ferritic steel, magnetic; Ni free, low cost, stable price; High thermal conductivity, low thermal expansion, good welding deformation resistance; Good high temperature corrosion resistance and high temperature strength; Due to the low carbon C content and the addition of Ti, no heat treatment is required after welding.Because of its excellent high temperature corrosion resistance and high temperature strength, it is widely used in the production of automobile exhaust system related parts, such as exhaust pipe, catalytic converter, return pipe pipeline, etc..
410LLow carbon C, low Chromium Cr ferritic steel, magnetic; Ni free, low cost, stable price; Good machinability, welding bending, high thermal conductivity, low thermal expansion rate.Because of its excellent performance, it is widely used in making refrigerated containers, container shells, automobile exhaust pipes, heat exchangers, boiler combustion chambers, furnace parts and nozzles, etc.
Martensite410SMarkovite system is a representative of steel, because it does not contain nickel Ni, low cost, stable price; This steel has high strength and good workability, but is not suitable for use in harsh corrosive environments; Higher hardness (magnetic) can be obtained after heat treatment.Because of its high strength and hardness, it is widely used in the manufacture of kitchen utensils, cutting tools and some mechanical parts.
