Furnace push rods are an important component in industrial furnaces, which are subjected to multiple tests such as high temperature, oxidation and corrosion, so the choice of material is crucial. Among heat-resistant stainless steels, ZG40Cr25Ni20Si2 and ZG35Cr24Ni7SIN are two commonly used materials.
ZG40Cr25Ni20Si2 is a high-chromium and high-nickel austenitic heat-resistant stainless steel, which has stable microstructure, strong resistance to high-temperature oxidation, and high toughness and corrosion resistance. This makes it able to maintain good mechanical properties and stability in high-temperature environments, so it is suitable for the manufacture of high-temperature components such as furnace pushrods.
ZG35Cr24Ni7SIN is a heat-resistant stainless steel containing nitrogen, which improves the strength and high temperature resistance of the material by adding an appropriate amount of nitrogen. It also has excellent resistance to oxidation, corrosion and thermal fatigue, so it is also widely used in the manufacture of high-temperature components such as furnace push rods.
On the whole, ZG40CR25NI20SI2 and ZG35CR24NI7SIN both heat-resistant stainless steel materials have high heat resistance, oxidation resistance, corrosion resistance and mechanical properties, so they show good durability in the use of furnace push rods. The specific choice of material also needs to be comprehensively considered according to the actual working conditions and use requirements to achieve the best use effect.
