SUS430 Japan SUS Series Stainless Steel

SUS430, Japan SUS series stainless steel. The steel grade of SUS430 ( F / FR ) stainless steel corresponding to the national standard is 1Cr17. The tensile strength is greater than 450, the yield strength is greater than 205, and the HBS is less than 183 ( the data is annealed ). It is commonly used for building decoration, heavy oil burner parts, etc. The addition of Ti or Nb and the reduction of C content in 430LX steel improved the processing performance and welding performance. It is used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc. 430 stainless steel, steel + more than 12 % chromium can prevent oxidation caused by natural factors, called stainless steel, in the JIS code for 430, so also known as 430 stainless steel. However, 430 stainless steel cannot resist the oxidation caused by chemical substances in the air. Because of the increasing number of acidic chemical substances in the air, 430 stainless steel will still be oxidized ( rusted ) due to unnatural factors after being used for a period of time.

Characteristics

Low price and good processability are ideal substitutes for SUS304. Stress corrosion resistance, typical non-heat treatment hardening ferritic stainless steel ;

Low thermal expansion rate, excellent oxidation resistance ;

430 stainless steel has good corrosion resistance and general steel, thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat fatigue resistance, adding stabilizing element titanium, mechanical properties of weld seam.

430F ( Y1Cr17 ) is a kind of steel with easy cutting performance on 430 steel. For automatic lathes, bolts and nuts, etc.

430 stainless steel has the following states, different states, dirty resistance and corrosion resistance are not the same. NO.1 : 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states. 2D is slightly shiny silver white, the process is : hot rolling + annealing shot peening pickling + cold rolling + annealing pickling ; 2B is silver white and has better gloss and flatness than 2D surface. The process is : hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling ; no.3 has better glossiness and coarse grain. The process is as follows : polishing and quenching and tempering rolling of 100 ~ 120 grinding material ( JIS R6002 ) for 2D or 2B ; no.4 has better luster and fine lines. The process is : polishing and quenching and tempering rolling of 2D products or 2B with 150 ~ 180 grinding materials ( JIS R6002 ) ; the HL is silver gray and has hair stripes. The process is : polishing the 2D or 2B products with appropriate particle size of the grinding material to make the surface appear continuous grinding.

Uses

Decorative materials and outdoor advertising boards ;

For products with stress corrosion resistance requirements ;

Electronic products, tableware, bolts, nuts, screens and burners, etc.

It is used for building decoration parts, fuel burner parts, household appliances and home appliance parts. It has good corrosion resistance in oxidizing acid solutions, especially nitric acid, so it is widely used in the manufacture of chemical equipment for the production of nitric acid, such as absorption tower, nitric acid heat exchanger, acid tank, conveying pipe and tank, and can also be used to make food, wine and other industrial pipes and tableware.
