Machinability
Type
410 has fair machinability. It has somewhat better machining
characteristics than austenitic stainless steels, having a
rating of about 55% compared to Bessemer screw stock (AISI B
1112). Sulfurized cutting oils are used for most operations.
Weldability
Type
410 has good weldability. It is readily joined by fusion and
resistance welding methods. Type 410 filler rod should be used
for weldments that will be annealed or hardened and tempered
after welding. Type 309 or 310 filler rod should be used to
obtain maximum weld metal ductility in the as-welded condition.
Ductility of fusion welds can be improved by annealing at
1450-1500° F and slow cooling.

Formability
Type
410 has reasonably good cold working properties and can be
moderately drawn and formed. Severe working should be done hot
with bars at 1350-1500° F.
Corrosion
Resistance
Type
410 provides a good corrosion resistance to air, water and some
chemicals. Its resistance to nitric acid, concentrated sulfuric
acid, dilute acetic acid and naphtha is satisfactory. It
also provides good resistance to food acids.
Forgeability
Type
410 can be readily forged at 2300° F. Preheat steel to 1800° F
for 2 hours, raise rapidly to 2300° F, soak for 4 to 6 hours,
forge, slow cool.
Heat
Treating
ANNEALING:
Heat slowly to 1550-1650° F cool to 1100° F in furnace, air
cool.
PROCESS ANNEALING: Heat to 1350-1450° F, air cool.
HARDENING: Heat to 1700-1800° F, oil quench. Follow by
stress-relief or temper.
TEMPERING: Heat to 1100-1400°F for 1 to 4 hours, air cool.
