13 8 Stainless Steel Heat Treatment

Air cool or oil quench to below 60 f to effect complete transformation to martensite.

13 8 stainless steel heat treatment. 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. Ati 13 8 alloy can be machined in both the annealed and hardened conditions. 13 8 ph steel provides a wide range of properties through a single precipitation hardening heat treatment.

Type 13 8 is a martensitic precipitation age hardenable stainless steel. Alloy 13 8 stainless is usually available in an annealed condition also known as solution heat condition or condition a. All lubricants and coolants particularly sulfur bearing should be removed prior to heat treatment brazing and pickling. In the annealed condition use machine speeds 20 to 30 percent lower than those used on 304 stainless steel.

Inert gas shielding with helium is preferred. 13 8 uns s13800. 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. Then treat at 1150 f 10 f for 4 hrs.

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. Heat treatment 13 8 stainless is available in the annealed condition which is also called the solution heat treat condition or condition a. Heat solution treated material at 1400 f 10 f for 2 hrs.
