Introduction to the material types, grades, performance and application industries of wide stainless steel wire mesh raw materials
| Steel Grade | characteristic | use | |
| profound Clan body steel | 304 18Cr-8Ni | As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It has good hot processing properties such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, use temperature -196oC~800oC). | Household products (category 1 and 2 tableware, kitchen cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, and ship parts. |
| 304L 18Cr-8Ni-Low Carbon | As a low-C 304 steel, its corrosion resistance is similar to that of 304 steel in general conditions, but after welding or stress relief, its resistance to intergranular corrosion is excellent. It can maintain good corrosion resistance without heat treatment and is generally used below 400 (non-magnetic, use temperature -196oC~800oC). | It is used in outdoor machines, building materials, heat-resistant parts and parts that are difficult to heat treat in the chemical, coal and petroleum industries that require high resistance to intergranular corrosion. | |
| 304J1 13Cr-7.7Ni -2Cu | Cu should be added, its formability, especially wire drawing and aging crack resistance are good, so it can be formed into complex shapes. Its corrosion resistance is the same as 304 steel. | Thermos bottles, kitchen sinks, pots, kettles, insulated lunch boxes, door handles, textile processing machines. | |
| 316 18Cr-12Ni -2.5Mo | Mo should be added, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and it can be used under harsh conditions. Excellent work hardening (non-magnetic). | Equipment for use in seawater, production equipment for chemicals, dyes, papermaking, oxalic acid, fertilizers, etc.; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts. | |
| 316L 18Cr-12Ni 2.5Mo low carbon | As the low C series of 316 steel, in addition to having the same properties as 316 steel, it has excellent resistance to intergranular corrosion. | Among the uses of 316 steel, products with special requirements for resistance to intergranular corrosion | |
| 321 18Cr-9Ni-Ti | As the low C series of 316 steel, in addition to having the same properties as 316 steel, it has excellent resistance to intergranular corrosion. | Aircraft, exhaust pipes, boiler drums. | |
| iron white body steel | 409L 11.3C-0.17Ni low C, N | Due to the addition of Ti element, its high temperature corrosion resistance and high temperature strength are better | Automobile exhaust pipes, heat exchangers, containers and other products that are not heat treated after welding |
| 430 16Cr | As a representative type of ferrite steel, it has a low thermal expansion coefficient and excellent formability and oxidation resistance. | Heat-resistant appliances, burners, heat exchangers, headers, etc. that are not heat-treated after welding | |
| horse Clan body steel | 410 13Cr-Low Carbon | As a representative steel of martensitic steel, although it has high strength, it is not suitable for use in harsh corrosive environments. It has good workability and can be hardened by heat treatment (magnetic). | Knife blades, mechanical parts, oil refining equipment, bolts, nuts, pump rods, Class 1 cutlery (knife, fork). |
| 420J1 13Cr-0.2C | High hardness after quenching, good corrosion resistance (magnetic) | Cutlery (knife), turbine blades | |
| 420J2 13Cr-0.3C | After quenching, the hardness is higher than 420J1 steel (magnetic) | Blades, nozzles, valves, rulers, cutlery (scissors, knives) | |
