Machinibility and Weldability Machinability is rated at 45% of B1112. Average cutting speed 75 ft/min. Easily welded by all commercial processes except forge or hammer welding. The resultant weld has good toughness and ductility. Annealing is recommended after forging to maintain maximum corrosion resistance. 304/304L can be forged between 2100°-2350° F. Do not forge below 1700° F |
