Applications and Features |
|
||||||||||||||||
( 1 ) Weld metal is martensitic structure with 13%Cr. ( 2 ) To prevent the crack in beads and HAZ, please apply preheat temperature: 200~300oC, PWHT: 700~760 oC. ( 3 ) Superior oxidation and corrosion resistance at 650 oC,. ( 4 ) Suitable for welding petro-refining and chemical industry, such as AISI 410 or 420 stainless steel. |
