13 8 stainless steel heat treatment.

Type 13 8 is a martensitic precipitation age hardenable stainless steel. Alloy 13 8 stainless steel in the annealed condition can be strengthened further by relatively low temperature heat treatment. In the annealed condition use machine speeds 20 to 30 percent lower than those used on 304 stainless steel. Solution treat from 1675 1725 f for 15 to 30 minutes at temperature.

13 8 ph steel provides a wide range of properties through a single precipitation hardening heat treatment. Alloy 13 8 stainless steel is used in aerospace components landing gear nuclear reactor components petrochemical industry injection molding equipment etc. Inert gas shielding with helium is preferred. Heat treating after overaging ph 13 8 mo stainless in the h 1150 and h 1150m overaged conditions will not respond to further aging treatments.

Ati 13 8 alloy can be machined in both the annealed and hardened conditions. Heat treatment 13 8 stainless is available in the annealed condition which is also called the solution heat treat condition or condition a. Then treat at 1150 f 10 f for 4 hrs. Heat solution treated material at 1400 f 10 f for 2 hrs.

Alloy 13 8 stainless is usually available in an annealed condition also known as solution heat condition or condition a. In order to allow a complete martensitic transformation the alloy is solution treated at 913 940 c for 15 to 30 minutes followed by air cooling or oil quenching to below 15 5 c. The principal features of type 13 8 are good resistance to general and stress corrosion cracking and high strength that is developed by a single low temperature heat treatment.
