Second, the 300 series of 1, 3041 cr18ni9 ( 06Cr18Ni10) SUS304 features: as currently one of the most versatile steel, it has good corrosion resistance, heat resistance, strength and mechanical properties at low temperature. Stamping, bending and other hot workability is good, no heat treatment hardening phenomenon ( - no magnetic, working temperature 196℃~800℃） USES: mainly used in household appliances, tableware, kitchen utensils and appliances, water heaters, boilers, food machinery, etc. ; At present in guangdong province with decorative stainless steel welded pipe manufacturing also get quite a lot of applications, such as haley, the Great Wall, south China, zhongshan, flange, yue yuen building, wan jia wu, lion, acquisitive crown and the emperor rise, higher number of stainless steel with material and products in guangdong province association of member companies of 304 stainless steel products. 2, 304 j1sus304j1 characteristics: Cu shall be added, its formability, especially good drawing resistance and aging resistance crack, and complex shape product forming can be performed. Its corrosion resistance and 304 steel is the same. USES: mainly used in vacuum flask, kitchen sink, pot, pot, heat preservation, lunch box, door handles, textile processing machine, etc. 3, 304 l00cr19ni10sus304l characteristics: as low C steel, 304 under the general condition, its corrosion resistance and 304 steel are similar, but after or eliminate stress after welding, the grain boundary corrosion resistance. Under the condition of without heat treatment, can also keep a good corrosion resistance, generally used under 400 ( - no magnetic, working temperature 196℃~800℃） USES: used in grain boundary corrosion resistant requirements of high chemical industry, coal, oil field open machine, building materials, heat resistant parts and heat treatment are difficult parts. 4, 3211 cr18ni9tisus321 characteristics: Ti element is added in the 304 steel to prevent grain boundary corrosion. Suitable for use under the temperature 430 ℃ ~ 900 ℃. USES: mainly used in medical instruments, building materials, chemical, agricultural, Marine parts, atomic energy industry, aircraft, exhaust pipe, boiler steam drum auto parts ( Windshield wipers, muffler, mold) 。 5, 3160 cr17ni12mo2sus316 features: should add Mo, so its corrosion resistance, resistance to atmospheric corrosion resistance and high temperature strength particularly well, and can be used in critical conditions. Excellent work hardening, No magnetic) USES: mainly used in water with equipment, chemical, dyes, paper making. Oxalic acid, fertilizer and other production equipment; The food industry, coastal facilities, rope, CD rod, bolts and nuts. In recent years, stainless steel belt material and products in guangdong province association of member enterprise, such as yi ding, wong sheng has begun to focus on production of 316 stainless steel pipe. 。 6, 316 l00cr17ni14mo2sus316l as low C series of 316 steel grade, besides have same characteristics with 316 steel, the grain boundary corrosion resistance. Usage: use 316 steel, against the grain boundary corrosion products with special requirements. 7, 309 s0cr23ni13mo2sus309s characteristics: cr - 23 13 ni high alloy steel stainless steel belt, excellent corrosion resistance and strength. Usage: suitable for the working temperature at 1000 ℃ of components. Exhaust machine, heat treatment furnace and heat exchangers, etc. 8, 310 s0cr25ni20si2sus310s features: has good oxidation resistance, corrosion resistance and high temperature resistance, due to high percentage of chromium and nickel, 310 s has much better creep strength, can continue to work at high temperatures, has good resistance to high temperature. USES: mainly used in boiler, exhaust machine, heat treatment furnace and heat exchangers, etc. 3, 1, 400 series, 409 l00cr12tisus409l features: the cheapest model, because of the added Ti element, therefore the high temperature corrosion resistance and high temperature strength is better. With a ferritic stainless steel ( Chrome steel) 。 USES: mainly used in automobile exhaust pipe, heat exchangers, such as container to heat treatment after welding products. 2, 4101 cr13sus410 characteristics: as the representative of the martensitic steel steel, while the intensity is high, but not suitable for critical corrosive environment. Its good workability, surface hardening heat treatment ( Magnetic) 。 Purpose: the blade, machine parts, oil refining device, bolt, nut, pumping rod, 1 kind of tableware ( Knife, fork) Yangjiang in guangdong jieyang, and other regions have certain application market. 3, 420 j12cr13sus420j1 characteristics: high after quenching hardness, good corrosion resistance, Magnetic) 。 Purpose: tableware ( Knife) , turbine blades 4, 420 j23cr13sus420j2 characteristics: after quenching, higher than 420 j1 steel hardness ( Magnetic) 。 USES: mainly in the blade, nozzle, valve, board feet, tableware, Scissors, knives) Field. 5, 4301 cr17sus430 features: as a representative of ferritic steel, low thermal expansion rate, excellent formability and oxidation resistance. USES: mainly used for heat resistant utensils, burners, household appliances products, 2 kinds of tableware, kitchen sink, external decoration materials, bolts, nuts, CD rod, screen mesh, etc.
