Max. temp. to maintain corrosion resistance is 1300 degrees F,
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).
Hot Working : 2000-2200 F
(1093-1204 C) is the proper hot work range. Annealing: 1200-1400 F
(649-760 C), followed by air cooling. Hardening: 1750-1850 F
(954-1010 C), oil quench for maximum hardness.
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 350-400 F
(177-204 C). Post-weld annealing is recommended to reattain maximum ductility.
Filler metal, when required, should be AWS E/ER410.
