Stellite 6 Hardfacing of Duplex Stainless Steel / Austenitic Stainless Steel(316L)
- Thread starter Life68
- Start date
There should be no PWHT for the austenitic stainless steel, duplex and superduplex stainless steels. Major concerns would be sensitization for the austenitic grades of stainless steel, and precipitation of intermetallic compounds for the duplex and superduplex stainless steels upon exposure to PWHT temperatures, which would result in poor toughness and reduced corrosion resistance.
