High-temperature alloy hot-rolled bar (GB/T14993-1994) is a kind of bar material mainly internal used in the manufacture of rotating parts, which not only has high surface quality and good dimensional accuracy, but also has excellent strength and toughness. This article introduces the main features, production process and application of this kind of steel bar.
Main features:
High-temperature alloy hot-rolled bar is mainly used in the manufacture of high temperature rotating parts, such as turbochargers and turbines. This kind of steel bar has the functions of high temperature Resistant and high strength. The main components of its alloy are chromium, nickel and cobalt, and the mineral waves can reach 30-37%. The material has excellent oxidation resistance and high temperature strength, and its service temperature can reach 950-1000°C. It has good formability, can weld and forge almost at any temperature.
Process Flow:
High-temperature alloy hot-rolled bar is made of high-temperature alloy ingot. The production process of steel bar can be divided into four processes: raw material inspection, heating, hot rolling and final inspection. Strict quality control is carried out in all production processes to ensure the quality of the product.
Applications:
High-temperature alloy hot-rolled bar is mainly used for the manufacture of high temperature rotating parts, such as turbochargers, turbines and compressors. It is also widely used in industrial aerospace and other areas. Due to its excellent oxidation resistance, wear resistance and high temperature strength, it is very suitable for high temperature working environment.
Conclusion:
High-temperature alloy hot-rolled bar (GB/T14993-1994) is a kind of bar material mainly used for the manufacture of rotating parts. It has high surface quality and good dimensional accuracy, excellent strength and toughness. It has excellent oxidation resistance and wear resistance, and its service temperature can reach 950-1000°C, which is very suitable for high temperature working environment.
