410 is the basic martensitic stainless which will attain high mechanical properties after heat treatment. It has good impact strength, corrosion and scaling resistance up to 1200 F (649 C).
Cutlery, steam and gas turbine blades and buckets, bushings, valve components, fasteners, screens and kitchen utensils.
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.
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 350-400 F (177-204 C). Post-weld annealing is recommended to reattain maximum ductility. Filler metal, when required, should be AWS E/ER410.
2000-2200 F (1093-1204 C) is the proper hot work range. Do not work this material below 1650 F (899 C).
Readily cold formed using most of the common practices.
1200-1400 F (649-760 C), followed by air cooling.
Temper for desired hardness, air or furnace cool.
1750-1850 F (954-1010 C), oil quench for maximum hardness.
