Material Summary

As a professional stainless steel supplier, we produce high quality 314 seamless pipe & tube. 

Stainless steel grade 314 is with high temperature resistance and oxidation resistance, good mechanical properties, which can withstand high temperature 1000 degrees ~ 1500 degrees. Nickel and chromium content are relatively high, in order to improve the oxidation resistance and creep strength of steel at high temperature. 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). Pipes can be used in many industrial areas, like petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries:
