Precipitation hardening stainless steels
Precipitation Hardened have a martensite structure in the solubilized state and annealed martensite and copper rich intermetallic compounds. It has good machinability and excellent weldability.
17-4PH -Used in a large number of applications, such as bolts, stud bolts, springs and other parts mechanically requested and exposed to attack in aggressive environments.
AISI 660 – Stainless steel finds application in forged gas turbine parts such as stud bolts, nuts and bolts. It is suitable to be used in temperatures up to 700 ºC corrosive environments such as gas turbine and in oxidizing environments for continuous services at 800 ºC.
