Precision casting of ZG1Cr18Ni12Mo3Ti (HEAT-RESISTING STEEL) is a process of producing high mechanical and physical properties components used in a variety of applications. The process of precision casting ensures superior total dimensional accuracy and consistency, even when dealing with complex cast components. It is a reliable and cost-effective way to produce components for various industries such as aerospace, automotive, and medical.

The heat-resisting steel is a type of steel that is known for its superior performance at high temperatures. ZG1Cr18Ni12Mo3Ti is a heat-resisting steel with high chromium, nickel, and molybdenum content; thus, providing excellent resistance to oxidation and sulfidation at elevated temperatures. The combination of the high chromium and molybdenum content provides excellent oxidation resistance compared to other heat-resisting steels, allowing it to withstand temperatures of up to 1100°C.

The low-magnification microstructure of precision-casted ZG1Cr18Ni12Mo3Ti is primarily an austenitic grain structure, with some ferrite present. The austenite has relatively evenly distributed grain size, few pores or inclusions, and is homogeneous and well-distributed. The ferrite islands appear as small coarse grains, providing additional strength and heat-resistance to the component.

To ensure the components mechanical and physical properties, the heat-treatment is crucial. This involves quenching the component in hot solution at temperatures of around 1100°C and then further ageing it at a lower temperature. Following the heat-treatment, the component is tested through tensile, hardness, and microstructure tests to ensure the component meets the required specifications and performance.

In conclusion, precision casting of ZG1Cr18Ni12Mo3Ti (HEAT-RESISTING STEEL) is a reliable and cost-effective way to produce components with excellent mechanical and physical properties. It is a heat-resisting steel with high chromium and molybdenum content which offers excellent oxidation and sulfidation resistance at elevated temperatures. The low-magnification microstructure of precision-casted ZG1Cr18Ni12Mo3Ti is primarily an austenitic grain structure, with some ferrite present, and must be heat treated to ensure its mechanical and physical properties.
