SUS321 (American Standard SATM a276 is equivalent to national standard 0Cr18Ni10Ti)

Chemical composition of 321:

Physical properties of 321:

321 solid solution state, mechanical properties of the alloy at room temperature:

Main characteristics of this alloy：

321 is a very stable stainless steel. When the temperature reaches 427-816 ° C and chromium carbide precipitates, it can still maintain good resistance to intergranular corrosion. Due to the addition of titanium in the composition, 321 alloy can still maintain stability when chromium carbide is formed

Metallographic structure of 321

321 alloy is austenite matrix in solution heat treatment state.

321 application areas：

It is a kind of alloy material with high temperature strength and high temperature oxidation resistance, which is widely used in many fields

1. Furnace tube, furnace tank and mesh belt of heat treatment furnace

2. Shafts, structural parts and containers with temperature resistance below 850 ℃

3. Anchors and pins of refractories widely used in cement kilns and utility boilers
