13 8 Stainless Steel Heat Treatment

13 8 ph steel provides a wide range of properties through a single precipitation hardening heat treatment.

13 8 stainless steel heat treatment.

Alloy 13 8 stainless is usually available in an annealed condition also known as solution heat condition or condition a. Heat solution treated material at 1400 f 10 f for 2 hrs. 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. Alloy 13 8 stainless steel is used in aerospace components landing gear nuclear reactor components petrochemical industry injection molding equipment etc.

Type 13 8 is a martensitic precipitation age hardenable stainless steel. Then treat at 1150 f 10 f for 4 hrs. Corrosion resistance is similar to 304 stainless with greatest resistance in the fully 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.

Alloy 13 8 stainless steel in the annealed condition can be strengthened further by relatively low temperature heat treatment. Solution treat from 1675 1725 f for 15 to 30 minutes at temperature. 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. Air cool or oil quench to below 60 f to effect complete transformation to martensite.

Ati 13 8 alloy can be machined in both the annealed and hardened conditions. 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. Inert gas shielding with helium is preferred.
