17-4pH forged Stainless Steel parts is generally air melted, consumable electrode electroslag remelting (ESR) and consumable electrode vacuum arc remelting (VAC CE) are available as optional refinements. The VAC CE processin particular lowers gas content, reduces and disperses inclusions,and minimizes alloy segregation during solidification. This results inimproved mechanical properties and cleanliness. Air-melted  17-4 PHStainless Steel will meet the magnetic Particle Inspection requirementsof Aerospace Materials Specification AMS 2303. Consumable electrodevacuum arc remelted  17-4 PH VAC CE meets the magneticParticle Inspection requirements of Aerospace Materials Specification AMS 2300.

FOllowing is forging methods of UNS S17400 forged steel rings, :

heateduniformly to 1177 – 1204 °C (2150 – 2200 °F) and held at temperature at least 15 minutes before forging. On sections over 19 mm (0.75 in.)diameter or thickness, the material should be heated for one-half hour perinch of thickness at 1177 – 1204 °C (2150 – 2200 °F) and held forone hour at temperature prior to forging. On reheating, it should be soaked thoroughly. After forging, sections should be cooled to 32 °C
(90 °F) to assure grain refinement. Then, to assure the best condition for the hardening operation, the parts must be reheated to 1024 – 1052 °C(1875 – 1925 °F) and air cooled (or oil quenched or water+polymer
quenched in small 17-4ph forged parts).
Small forgings of 17-4ph forging material may be air cooled. Complex shapes and large forgings of 17-4ph forging parts should be equalized at about 1038 – 1149 °C (1900 – 2100 °F)
before cooling, cooled in air until black, and then slowly cooled to 32 °C (90 °F) under cover of light-gauge nongalvanized sheet or a thin insulating blanket.
