Carbon (C): 1. Improves blade deformation resistance and tensile strength; 2. Increases hardness and improves wear resistance.
Chromium (Cr): 1. Increases hardness, tensile strength, and toughness; 2. Protects against wear and corrosion.
Cobalt (Co): 1. Increases hardness and strength, allowing it to withstand high-temperature quenching; 2. Used in more complex alloys to enhance certain individual properties of other elements.
Copper (Cu): 1. Increases corrosion resistance; 2. Increases wear resistance.
Manganese (Mn): 1. Increases hardenability, wear resistance, and tensile strength; 2. Removes oxygen from the molten metal through oxidation separation and vaporization separation; 3. When added in large quantities, it increases hardness but also increases brittleness.
Molybdenum (Mo): 1. Increases strength, hardness, hardenability, and toughness; 2. Improves machinability and corrosion resistance.
Nickel (Ni): 1. Increases strength, hardness, and corrosion resistance.
Phosphorus (P): Enhances strength, machinability, and hardness.
Silicon (Si): 1. Enhances ductility; 2. Increases tensile strength; 3. Removes oxygen from the molten metal by separating oxidation and vaporization.
Sulfur (S): Small amounts can improve machinability.
Tungsten (W): Increases strength, hardness, and toughness.
Vanadium (V): Increases strength, hardness, and shock resistance.
