List of elemental properties of (alloy steel):
Nickel (Ni): Nickel can improve the strength of steel while maintaining good plasticity and toughness. Nickel has high corrosion resistance to acid and alkali, and has rust and heat resistance at high temperatures. However, as nickel is a relatively scarce resource (with a high price), it is advisable to use other alloying elements instead of nickel chromium steel.
Chromium (Cr): In alloy steel, chromium can significantly improve strength, hardness, and wear resistance, while reducing plasticity and toughness. Chromium can also improve the oxygen and corrosion resistance of steel, making it an important alloying element in stainless steel and heat-resistant steel.
Molybdenum (Mo): Molybdenum can refine the grain size of steel, improve hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperatures (deformation occurs due to long-term stress at high temperatures, known as creep). Adding molybdenum to alloy steel can improve its mechanical properties. It can also suppress the brittleness of alloy steel caused by fire
