Bimetallic thermometer 430 what is the difference between stainless steel and 304 stainless steel

304 stainless steel and 430 stainless steel is: 1, the corrosion resistance: 430 stainless steel containing chromium 16. 00 - 18. 00%, basically do not contain nickel metal, more than 304 stainless steel containing chromium nickel metal, so the corrosion resistance of 430 stainless not as good as 304 stainless steel. 2, stable performance: 430 stainless steel is ferrite morphology, 304 is austenitic stainless steel, 304 stainless steel is better than 430 stainless steel was stable, 3, resilience: 304 stainless steel has a strong toughness, better than 430 stainless steel toughness 3, heat conduction performance: 430 stainless steel and ferritic than 304 austenitic stainless steel heat conduction performance is good, 4, mechanical performance: 430 stainless steel added stability of chemical elements, mechanical properties of weld parts is better than 304 stainless steel, 430 stainless steel using areas: 1, 430 stainless steel is mainly used in architectural decoration, fuel burner components, home appliances, home appliance parts. 2, in 430 with the performance of free-cutting steel steel grade 430 f, is mainly used in automatic lathe, bolts and nuts, etc. 3, Ti and Nb is added in the 430 steel, to reduce the C content into 430 lx, improved the processing properties and welding performance, is mainly used for hot water, heating water system, sanitary ware, families with durable appliance, bicycle flywheel, etc. 304 stainless steel using field: 1, 304 stainless steel with high temperature resistance, good processability, high toughness characteristics, widely used in medical industry and furniture decoration industry and food industry. 2, 304 stainless steel has a strong corrosion resistance, is widely used for making good comprehensive performance ( Corrosion resistance and formability) Equipment and parts. Conclusion: 304 stainless steel and 430 stainless steel have their own advantages: 430 stainless steel has good thermal conductivity and mechanical properties, building decoration, fuel burner components, family appliances, household appliances and other fields, 430 stainless steel is better; 304 stainless steel has a strong toughness and corrosion resistance, in the industrial and food medical need corrosion resistance performance of the industry, such as 304 stainless steel is better.
