Stainless Steel

APPLICATIONS & WELDING

With an excellent resistance to corrosion and oxidation, stainless steel are used in several industries.

Due to the variety of their metallurgical characteristics, those steels are divided into several grades where each having different weldability and facing certain challenges during welding :

  • Austenitic : hot cracking sensitivity
  • Ferritic : embrittlement at 475°C, loose of mechanical properties in case of overheating
  • Martensitic : cold cracking sensitivity
  • Duplex : embrittlement at 475°C, loose of mechanical properties in case of overheating
  • Hardening by precipitation (PH) : can be of austenitic, semi-austenitic or martensitic type and are therefore likely to present the complications already mentioned

In addition, all stainless grades can undergo a heat-tint of joints and of the heat affected zone, synonymous of oxidation and of loose of corrosion resistance which make their particularity. The welding procedure to follow and the choice of filler metal will be essential to insure the integrity of the welding.
