Austenitic SUS 304 stainless steel and ferrite SUS 430 stainless steel

Compared with austenitic series SUS 304 stainless steel , ferrite series  SUS 430  stainless steel is cost-effective for corrosion resistance, good heat thermal conductivity, small coefficient of thermal expansion, and less stress. Various types of excellent properties such as corrosion corrosion (Fress Corrosion Cracking), ferrite series SUS 430 stainless steel is used in automotive exhaust system components, roofing, doors and windows, building materials, kitchens, water storage tanks, hot water tanks, etc. Wide range of uses such as materials.

When these structures are produced, Austenitic SUS 304 stainless steel and ferrite SUS 430 stainless steel  are often cut and formed into an appropriate shape, and then joined by welding. However, since the C and N solid solubility limits of the ferrite series SUS 430 stainless steel are small, Cr carbonitride is generated in the welded portion due to deuteration and solidification by welding. A phenomenon known as sensitization is formed by forming a depletion layer and easily causing a decrease in corrosion resistance.Therefore, a method of suppressing the generation of Cr carbonitride by suppressing the formation of Cr carbonitride by adding Ti or Nb having an affinity for carbon and nitrogen to Cr is suppressed.
