Cobalt Co20 heat-resistant steel slider

Cobalt Co20 heat-resistant steel sliderIt is a high-temperature component made of cobalt based alloy (Co20) as the core material, which has excellent properties such as high temperature resistance, oxidation resistance, corrosion resistance, and wear resistance. It is widely used in high-temperature operation scenarios such as metallurgy, chemical industry, aerospace, etc., especially in the heating furnace of steel rolling mills.

heat resistance

Co20 alloy can maintain stable mechanical properties at temperatures of 1200 ℃ or even higher, making it suitable for high-temperature equipment such as heating furnaces and heat treatment furnaces. Its high-temperature strength far exceeds that of ordinary stainless steel and can withstand thermal loads.

Oxidation resistance and corrosion resistance
The dense oxide film formed on the surface effectively resists high-temperature oxidation and corrosive media (such as slag and sulfurizing gas) erosion, extending the service life. It performs particularly well in corrosive environments such as chemical and petroleum industries.

wear resistance
High hardness and toughness make it less prone to wear under friction and impact, reducing the frequency of equipment downtime for maintenance. At a high temperature of 1200 ℃, its wear resistance is 3-5 times that of ordinary stainless steel.

thermal shock resistance
After tens of thousands of rapid cooling and heating cycles, the structure remains intact, avoiding the problem of cracking of ordinary sliders due to thermal stress and ensuring stable operation of the equipment.

Metallurgical industry: The discharge end of the heating furnace in the steel rolling mill, the high-temperature section of the fixed beam, and the walking beam support and guide the heating of the metal billet to prevent deformation and furnace bottom burning.

Chemical and petroleum industries: high-temperature reactors, pipeline transportation systems, etc., resistant to corrosive media and high-temperature wear.

manufacturing process

Precision casting: using silica sol casting technology to ensure dimensional accuracy (tolerance ± 2mm) and surface quality (smooth and defect free), reducing installation errors and operational failures.

Heat treatment: Optimizing material structure through water toughening treatment to enhance toughness and fatigue resistance.
