The creation of metal alloys account for 85% of the available chromium's usage. The remainder of chromium is used in the chemical, refractory, and foundry industries. The strengthening effect of forming stable metal carbides at grain boundaries, and the strong increase in corrosion resistance made chromium an important alloying material for steel. High-speed tool steels contain between 3 and 5% chromium. Stainless steel, the primary corrosion-re… WebResistivity = (Resistance * Area ) / Length. So the resistance for both the wires is supposed to be same , and ratio of diameters is given , from which you can deduce the ratio of Areas of the two wires and the values of the resistivity for both wires is given.
