As a key component to withstand high temperature environments, the choice of material is crucial. Among the many metal materials, heat-resistant steel is the first choice in this field due to its excellent high-temperature performance. Among them, ZG40CR25NI20 and ZG35CR26NI12 have been widely used in the manufacture of furnace tube hooks because of their unique composition and excellent performance.
ZG40Cr25Ni20 heat-resistant steel, with its chromium content of up to 40% and nickel content of 25%, gives it extremely strong resistance to high-temperature oxidation and corrosion. At high temperatures, this steel retains high strength and hardness, effectively preventing deformation and damage to the furnace tube hook. At the same time, its good thermal stability and oxidation resistance enable it to operate stably for a long time at high temperatures, ensuring the safety and efficiency of the furnace.
ZG35CR26Ni12 heat-resistant steel, although its chromium and nickel content is slightly lower than ZG40CR25NI20, its comprehensive properties are also excellent. Its 35% chromium content and 26% nickel content guarantee excellent resistance to corrosion and oxidation at high temperatures. In addition, the steel also has good toughness and plasticity, making it easy to process and shape during the manufacturing process, and can meet the needs of various complex furnace tube hook structure designs.
In general, ZG40Cr25Ni20 and ZG35Cr26Ni12 are two heat-resistant steel grades, with their excellent high temperature resistance, good mechanical properties and easy processing, which play an irreplaceable role in the manufacture of furnace tube hooks, and provide a solid guarantee for the safe and stable operation of the heating furnace.
