Type 316 (UNS S31600)

Description

Type 410 QDT is a quenched and double tempered, 12 percent chromium martensitic stainless steel suitable for general purpose applications that is corrosion resistant to fresh water and mild acids and alkalies.  Type 410 is suitable for applications not demanding high corrosion resistance and can be used up to 1200˚F (649˚C) where resistance to scaling and oxidation is required.  Type 410 is used for pumps and oil refinery equipment, nuclear and airframe applications, and vanes and blades in jet engine compressors.

Type 410 possesses resistance to atmospheric corrosion because it forms a tightly adherent oxide film that protects the surface from attack.  The maximum corrosion resistance is obtained by hardening and polishing to a smooth surface finish.  Type 410 resists oxidation up to 1500˚F (816˚C) but for continuous service the temperature should not exceed 1200˚F (649˚C).  A wide range of properties may be obtained by hardening and tempering this stainless steel.  This material is double tempered after quenching to relieve internal stresses and it also guarantees that no untempered martensite remains in the bar.
