|Ultimate Tensile Strength||150000|
|Machinability and Weldability
Machinability in the annealed condition is rated at 48% of B1112. Average cutting speed 80 ft/min. 17-4 is readily weldable by all the conventional processes. Preheating and post-heating practices used for the standard hardenable stainless grades are not required. 17-4 can be forged between 2050Â°-2150Â° F. Do not forge below 1850Â° F. Forgings are air cooled to 90Â° F or lower.
