The main characteristics of this alloy:
314 is an austenitic heat-resistant and corrosion-resistant stainless steel material. It has all the properties of austenitic stainless steel. Because it contains 2% silicon, it also has high temperature and oxidation resistance, so it is also known as a representative of heat-resistant steel. The maximum operating temperature is 1200 กใ C. Because of high nickel (Ni) and chromium (Cr) content, it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance
Metallographic structure of 314
Alloy 314 is an austenite matrix in the solution heat treatment state.
314 application areas
It is an alloy material with high temperature strength and high temperature oxidation resistance. It is mainly used for mesh belts:
1. Furnace tube, furnace tank, mesh belt of heat treatment furnace
2. Shafts, structural parts and containers with a temperature resistance up to 1150 ℃
