Comparison of 304 stainless steel and 430 stainless steel:
1. Corrosion resistance: 430 stainless steel contains 16.00-18.00% chromium, which is basically free of nickel metal. 304 stainless steel contains more chromium and nickel metal, so 430 stainless steel corrosion resistance is better than 304 stainless steel.
2, stability: 430 stainless steel is ferrite, 304 stainless steel is austenitic, 304 stainless steel is more stable than 430 stainless steel,
3, toughness: 304 stainless steel has a strong toughness, stronger than 430 stainless steel
3, thermal conductivity: 430 stainless steel ferrite is better than 304 stainless steel austenitic heat transfer performance,
4, mechanical properties: 430 stainless steel added a stable chemical element of titanium, the mechanical properties of the weld site is better than 304 stainless steel,
430 stainless steel use areas:
1,430 stainless steel is mainly used for building decoration, fuel burner parts, household appliances, home appliances parts.
2, 430 steel with easy-cutting steel grade 430F, mainly used for automatic lathes, bolts and nuts.
3. Adding Ti or Nb to 430 steel, reducing C content to 430LX, improving processing performance and welding performance, mainly used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc. .
304ainless steel use field:
1, 304 stainless steel has the characteristics of high temperature resistance, good processing performance and high toughness. It is widely used in industrial and furniture decoration industry and food medical industry.
2, 304 stainless steel has strong corrosion resistance, widely used in the production of equipment and parts that require good comprehensive performance (corrosion resistance and formability).
Summary: 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 parts, household appliances, home appliances parts and other fields, 430 stainless steel is better; 304 stainless steel has very Strong toughness and corrosion resistance, in the industry and food and medical industries that require corrosion resistance, 304 stainless steel is better.
