Manufacturing Process
Stainless steel grade 314 can be heat treated by annealing the material at 1038-1149°C (1900-2100°F), and then quenching in water or rapidly air cooling. Grade 314 steel can be hardened only through cold working. To perform machinability of grade 314, coolant and high-speed turning tools are recommended.
After slowly heating the material to 871°C (1600°F), it should be thoroughly soaked, and then followed by quickly heating to 1093 -1232°C (2000-2250°F) , to perform forging, flanging, or working.
Applications
Grade 314 steel is widely used in the following applications:
· Radiant tubes
· Equipment for furnaces
· Heat treatment components
· Annealing and carburizing boxes
Introduction
Stainless steel grade 314 has excellent high-temperature resistance characteristics among the chromium-nickel steels series. The silicon content in this material improves oxidation and carburization resistance; however, it can become very brittle when subjected to prolonged temperatures of 649-816°C (1200- 1500°F).
