0.2 % Proof Stress (N/mm2) at Elevated Temperatures
Hot forming temperature: 1100-850oC.
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.
Embittlemnt: It must be in mind that the temperature range between 425 and 525oC must be avoided owing to embritllement at 475oC.
Not known for its exceptional corrosion resistance, this alloy will stand up well to mild atmospheric conditions and fresh waters.
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 meta.
