Machining is tough, draggy chips along with heavy build-up. While this alloy can be machined in the annealed condition, it has tendency to act better in the cold drawn or heat treated condition.
WeldingWith this alloy most common techniques of welding can be successfully utilized. It is advisable to preheat the workpiece to 350-400 F (177-204 C) to reduce the chance of cracking. Post-weld annealing is recommended to reattain maximum ductility. Filler metal, when required, should be AWS E/ER410.
Hot Working2000-2200 F (1093-1204 C) is the appropriate hot work range. Do not work this material beneath 1650 F (899 C).
Cold WorkingCold Working is promptly formed by utilizing the most common practices.
Annealing1200-1400 F (649-760 C) followed by air cooling.
TemperingTemper for desired hardness, air or furnace cool.
HardeningHardening at 1750-1850 F (954-1010 C) oil quench for maximum hardness.
