17-4 stainless is an age-hardening martensitic stainless combining
high strength with the corrosion resistance of stainless steel.
Hardening is achieved by a short-time, simple low-temperature
treatment. Unlike conventional martensitic stainless steels, such
as type 410, 17-4 is quite weldable. The strength, corrosion
resistance and simplified fabrication can make 17-4 stainless a
cost-effective replacement for high strength carbon steels as well
as other stainless grades.
At the solution treating temperature, 1900°F, the metal is
austenitic but undergoes transformation to a low-carbon martensitic
structure during cooling to room temperature. This transformation
is not complete until the temperature drops to 90°F. Subsequent
heating to temperatures of 900-1150°F for one to four hours
precipitation strengthens the alloy. This hardening treatment also
tempers the martensitic structure, increasing ductility and
toughness.
