What are the alloy elements of heat-resistant steel? Different metal elements have different characteristics.
Alloy elements (Molybdenum and Nickel) in heat-resistant steel
Molybdenum is a refractory metal element that can form hard and stable carbides, thereby enhancing hardenability, strength, toughness, wear resistance and corrosion resistance. Molybdenum is most commonly used as a high-temperature metal alloy in steel, cast iron, and high-temperature alloys in the military, defense industry, semiconductor and special machinery workshops.
Nickel is a naturally occurring silver-white shiny metal with a golden hue. It is malleable, ductile, and has excellent strength and corrosion resistance. Nickel is often used in stainless steel and other alloys to make it stronger. Nickel alloys are used in gas turbines, power generation, aircraft, special engineering and electronics. Tantalum Tantalum is a shiny silver metal that softens when pure. Because of the oxide film on its surface, it actually has corrosion resistance. Tantalum is particularly useful in high temperature applications in aircraft engines and electronic equipment.
Heat-resistant steel 15CrMo has become a standard material in the steel heat treatment industry, and has good oxidation resistance and high melting point. Therefore, it can withstand high temperatures (℃)
The excellent strength of 15CrMo heat-resistant steel been widely used and it is often used in boilers.
