Tensile strength to the alloy
In addition to iron, carbon and chromium, modern stainless steel may also contain nickel, niobium, molybdenum and titanium. Nickel, niobium, molybdenum, and Chromium improve the corrosion resistance of stainless steel. Therefore, stainless steel in addition to iron-nickel and chromium imparts tensile strength to the alloy.
So, the correct option is (B)
