H10665Alloy properties:
The main differences between this alloy and HuaNickel H10665 alloy are the low carbon and silicon content (C≤ 0.02%, Si ≤0.10%) in the chemical composition, and the iron content from less than 6% to less than 2%. Due to the change of carbon, silicon and iron content, although the matrix structure of 0H10665 alloy is no different from H10665 alloy, the precipitated phase on the alloy matrix or along the grain boundary is very different. The most obvious feature is that the intermetallic phase and carbide precipitation phase of 00Mo28Ni68Fe2 alloy are significantly reduced. The corrosion resistance of 00Mo28Ni68Fe2 alloy (including comprehensive corrosion resistance and intergranular corrosion resistance) is significantly improved.
H10665Uses of alloys:
H10665 alloy can be used to produce plates, pipes (welded pipes), rods, wires, strips and forgings. It is mainly used for pipelines, vessels and their linings, reaction towers and linings, pumps and valves that are resistant to hydrochloric acid, sulfuric acid, phosphoric acid and formic acid. For conditions that require welding, it is better to choose 0H10665 instead of H10665 alloy.
H10665Process performance:
Welding process: 0H10665 alloy has good welding performance, and because the carbon, silicon and iron content in this alloy are low, the intergranular corrosion resistance and knife edge corrosion resistance after welding are better than 0H10665. When the amount of iron and chromium in the alloy is appropriately controlled, the plasticity, toughness, corrosion resistance and weldability of 0H10665 alloy will be further improved. As a result, HuaNickel 0H10665 does not need to be heated. This alloy is more suitable than 0H10665 alloy for the manufacture of welding equipment and components.
Heat treatment: This alloy needs to be treated with 1066°CSolid solution except for special uses. Except for those whose Fe+ Cr content in the alloy is controlled, it is generally not allowed to stay and use it for a long time between 538~816 °C.
