Valve Stems are often made out of ASTM A182 Gr F6a Cl 3
materials. When these stems are required for NACE MR0175 service, these have to be double tempered. However, the ASTM standard A182 does not list the properties after double tempering. Can any body help me with an authentic source for the mechanical properties of this material after double tempering is carried out.
