In the heat treatment process of vacuum furnace, the material selection of the material is very important as an important part of the workpiece. Considering the stability and durability of the material in high-temperature environments, heat-resistant steel became an ideal choice. Among the many heat-resistant steel grades, ZG40Cr25Ni20Si2 and ZG4Cr28Ni48W5 have attracted attention for their excellent performance.
ZG40CR25Ni20Si2 is a high-chromium, high-nickel heat-resistant steel with good oxidation resistance and high temperature strength. In the high temperature environment of 1200-1300 meters, the material can remain stable for a long time and is not easy to deform or damage. In addition, its excellent thermal conductivity results in a more uniform heat distribution, which improves the efficiency and quality of heat treatment.
ZG4CR28Ni48W5 is also a heat-resistant steel with excellent high temperature resistance. Through rational composition design and advanced smelting process, the material has excellent oxidation resistance and creep resistance at high temperatures. Under the condition of 1200-1300 years, ZG4CR28Ni48W5 can maintain a long service life and ensure the continuity and stability of heat treatment in the vacuum furnace.
In summary, ZG40Cr25Ni20Si2 and ZG4Cr28Ni48W5 are two heat-resistant steel materials that show good durability for the heat treatment tray of the vacuum furnace. In practical application, according to the specific use environment and requirements, the suitable material can be flexibly selected to ensure the smooth progress of the heat treatment of the vacuum furnace.
