Nickel is a silvery, hard, ductile, ferromagnetic metallic element used in alloys, in corrosion resistant surfaces, batteries and for electroplating.
Effects of Nickel in steel alloys
Nickel is used to increase hardness, tensile strength, wear and shock resistance and toughness. It is the main alloying element in stainless steel uses where shock or stress will be present in the steel. Nickel is not used with high carbon steels which would make the machining more difficult.
- (+) Increases strength.
- (+) Increases toughness.
- (+) Increases wear and shock resistance.
- (+) Increases corrosion resistance.
- (-) Difficult to machine in high carbon steels.
