Heat Treatment

Heat Treatment

Common heat treatment processes of ss 430 round bars/flat bars:

  1. Annealing
    • Temperature: 760-815°C (1400-1500°F)
    • Process: Heat slowly and cool in air to relieve internal stress and improve ductility.
  2. Stress Relieving
    • Temperature: 200-300°C (390-570°F)
    • Process: Heat and air-cool to reduce residual stress after machining or forming.

Note: 430 stainless steel cannot be hardened by heat treatment due to its ferritic structure.
