Properties of minor metals in steel



Properties of minor metals in steel :-

• Manganese : Desulpherising (sulphur causes steel to crack) and as alloying element for strength and toughness.

• Silicon : Used to de-oxidise steel

• Nickel : Anti-corrosion (nickel content in high quality stainless steel 8-10% )

• Chromium : Resistance to corrosion, temperature and wear (used in stainless steel (average content 18%)

• Zinc : Used to galvanise steel (enhances corrosion resistance)

• Tin : Brings protective coating to steel (used in food and drink cans)

• Molybdenum : Resistance to heat, corrosion(high-end steel). Brings weld ability to steel (construction steel)

• Vanadium : Brings extreme hardness to steel (high-strength steel)

• Tungsten : Brings extreme hardness to steel (high-speed steel)
