What material is AMonel400 is a corrosion-resistant alloy with large usage, wide range of uses and excellent comprehensive properties. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and also has excellent corrosion resistance against hot concentrated alkali liquid. It is also resistant to corrosion from neutral solutions, water, seawater, atmosphere, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracking and has good cutting performance.lloy 400 made of?

Generally speaking, steel with a chromium content of 10.5% is less likely to rust. The higher the chromium and nickel content, the better the corrosion resistance. For example, the nickel content of 304 material is 8-10%, and the chromium content reaches 18-20%. Such stainless steel will not rust under normal circumstances.

Mechanical properties: In terms of fatigue strength, 201 stainless steel has greater hardness, toughness, and fatigue resistance than 304 stainless steel.

There are certain differences between 304 and 304L in terms of composition, performance and use. Especially in terms of carbon content, 304L is an ultra-low carbon stainless steel with a carbon content reduced to less than 0.03%. On the basis of improving the corrosion resistance of stainless steel, it can also improve the corrosion resistance of 304 caused by the precipitation of chromium carbide between 450 and 860°C. Intergranular corrosion caused by sensitization and welding, and 304L has better welding performance. Of course, the price of 304L is also relatively high; but it is worth noting that neither 304 nor 304L is resistant to corrosion by media containing chloride ions. It needs to be selected according to the specific usage scenario.
