Main characteristics of this alloy:

314 belongs to austenitic type heat-resistant and corrosion-resistant stainless steel, which has the properties of all austenitic stainless steels. Because it contains 2% silicon element and has strong high temperature and oxidation resistance, it is also called the representative of heat-resistant steel, with the maximum service temperature of 1200 ℃. Due to the high content of nickel (Ni) and chromium (CR), it has good oxidation resistance, corrosion resistance, acid alkali resistance and high temperature resistance

Metallographic structure of 314

314 alloy is austenite matrix in solution heat treatment state.

314 application fields include:

It is a kind of alloy material with high-temperature strength and high-temperature oxidation resistance, mainly used for making mesh belt: < br clear = "all" / > 1. Furnace tube, furnace tank and mesh belt of heat treatment furnace

2. Shafts, structural parts and containers with temperature resistance below 1150 ℃
