News - Inconel 600 high temperature alloy

Inconel is a superalloy, Inconel 600 is often referred to as “GH3600″ “GH600″ is a nickel-based superalloy. It has good high temperature performance, corrosion resistance and good mechanical strength. Suitable for use in high temperature, high pressure and corrosion resistant environments. It is widely used in aerospace, petrochemical, nuclear energy and medical fields.

Inconel 600 is mainly composed of nickel (Ni) and chromium (Cr), and its chemical composition also includes a small amount of iron (Fe), carbon (C), silicon (Si), manganese (Mn), sulfur (S) and other elements. The specific chemical composition ratio is as follows:

Inconel600 characteristic:

Physical properties:

Density: 8.43-8.47g /cm³ Melting point: 1370-1425°C3 Thermal conductivity: 14.8W /(m·K)

Linear expansion coefficient: 13.3 × 10⁻⁶/K Tensile strength: 550 MPa Yield strength: 240 MPa

Elongation: 30%

Corrosion resistance: Inconel 600 performs well in various acidic (such as sulfuric acid, phosphoric acid, hydrochloric acid, etc.) and alkaline solutions, as well as in chloride media. The addition of chromium significantly improves the oxidation resistance of the alloy, so that it can run stably in high temperature and corrosive environment for a long time, and is not easy to appear oxidation damage.

High temperature strength: The alloy has excellent high temperature strength and can maintain high mechanical properties even at high temperatures. Its tensile strength can reach 550 MPa at room temperature, and its yield strength is about 240 MPa.

Machinability: Inconel 600 has good machinability and can be formed by forging, rolling, welding and other processes. Its rational chemical composition design makes the alloy easy to process and adapt to complex manufacturing requirements.

Oxidation resistance: Chromium in the alloy can form a dense oxide film, which effectively protects the alloy from oxidative corrosion.

Thermal shock resistance: Cornel 600 alloy can withstand rapid temperature changes without cracking.

Inconel 600 Production technology:

The production process of Inconel600 is a complex process involving multiple links, which requires strict control of the process parameters and quality indicators of each link to ensure the quality and performance of the product. It mainly includes the following steps:

1. Raw material preparation: The high purity metal or compound of various alloy elements is mixed together and weighed to ensure the uniformity of alloy composition.

2. Melting: Put the prepared raw material into the melting equipment and melt it into liquid metal alloy by heating to high temperature. In the melting process, the temperature and atmosphere need to be strictly controlled to avoid the introduction of impurities and ensure the uniformity of the alloy composition.

3. Casting: The molten alloy liquid is poured into the mold and cooled to form a solid block material, usually a block casting billet or sheet.

4. Heat treatment: Casting billets usually need to be heat treated, including solution treatment, aging treatment and stress annealing steps to eliminate residual stress in the material and improve the plasticity and strength of the material.

5. Deformation processing: The casting blank is subjected to deformation processing processes such as hot rolling, cold rolling, forging, drawing and pressure processing to obtain the required shape and size.

6. Machining: Surface treatment to remove oxide layer and other surface impurities to further improve surface finish and flatness.

7. Quality control: Through the use of advanced testing equipment and analysis technology, the product testing and analysis. At the same time, it is also necessary to strictly check the appearance quality and dimensional accuracy of the product to ensure that it meets production standards and customer requirements.

8. Cleaning and packaging.
