Corrosion properties
The corrosion resistance of Sandvik 1RK95 is between that of the stainless 13% chromium steels and the austenitic stainless steels of the ASTM 304 type. Sandvik 1RK95 has showed good resistance to corrosion attack in the annealed and precipitation hardened condition during salt spray testing according to standard ISO 9227:2006 at 35°C (95°F) in 5% NaCl.
Welding
Due to the low carbon content Sandvik 1RK95 is readily weldable using common welding methods. If welding is performed following tempering, a softer heat affected zone (HAZ) is to be expected adjacent to the weld metal. It is possible to temper the welded material, but in order to get the best material properties it is recommended to perform a solution annealing prior to tempering.
