Forging
Hot forming temperature: 1100-800oC, slow cooling in furnace or in thermoinsulating material.
Machinability
Tough, draggy chips with heavy build-up. While this alloy can be machined in the annealed condition, it tends to perform better in the cold drawn or heat treated condition.
Welding
Most common methods of welding can be successfully employed with this alloy. To reduce the chance of cracking, it is advisable to preheat the workpiece to 177-204oC. Post-weld annealing is recommended to reattain maximum ductility. Filler material is KW10-IG.
Corrosion Resistance
Not known for its exceptional corrosion resistance, this alloy will stand up well to mild atmospheric conditions and fresh waters.
