Heat Treating Stainless Steels Table Chart

Engineering Materials
Applications & Design

Stainless steels are heat-treated based on the stainless steel type and the target end item requirements. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.

  1. Cool slowly in furnace.
  2. Usually air-cooled but may be furnace cooled.
  3. Suffixes A, B, and C denote three types of steel differing only in carbon content. Suffix F denotes a free machining steel
  4. Cool rapidly in air.
