Preparation for Delivery S5. Intended generally for machining where an overhauled surface is desired, essentially for machined step down shafts or parts machined in short lengths of 3 ft 0. Material is selected from heats of known, good hot malleability. NOTE X1. In such cases, the user should run pilot forging tests to ensure himself that such material has the desired hot malleability range. Provides for better surface inspection than does hot-worked material and often employed where welding is involved where removal of mill oxide is desired.
