Manganese between 1.5 to 5% in steel makes it harder and more brittle. It can also be used for shafts, springs, gears, steering knuckles and drop forged parts Manganese steel When vanadium is added up to 0.25%, the elastic limit of the steel is raised by 50% can resist high alternating stresses and severe shocks. Vanadium when added even in small proportion to an ordinary low carbon increases significantly its elastic limit and fatigue resistance property. Steel having 45% Ni steel possesses extension equal to that of glass, a property very import making links between the two materials i.e. If Ni is present up to 27%, it makes the steel non-magnetic and non-corrodible. Invar (Ni 36%) and super-invar (Ni 31%) are the popular materials for least coefficient of expansion and are used for measuring instruments, surveyor tapes and clock pendulums. ![]() Steel having 25% Ni makes it stainless and might be used for I.C. Steel containing Nickel has very high tensile strength. Steel having Ni from 0.3 to 5% raises elastic limit and improves toughness. Steel having 2% Ni makes steel more suitable for rivets, boiler plates, bolts and gears etc. The percentage of Nickel varies from 2 to 45 in steel.
