Mechanical Properties
| Ultimate Tensile Strength | 85,000 |
| Yield Strength | 35,000 |
| Brinell Hardness | 180 |
| Elongation | 55% in 2 |
| Machinability 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. |
