Detailed explanation-1: -Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals. Completely and infinitely recyclable, stainless steel is the “green material” par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Detailed explanation-2: -Hence, Stainless steel is an alloy of iron, chromium, nickel, and some other elements in smaller proportions.
Detailed explanation-3: -Stainless steel is an iron and chromium alloy. While stainless must contain at least 10.5% chromium, the exact components and ratios will vary based on the grade requested and the intended use of the steel.
Detailed explanation-4: -The alloying element that makes steel ‘stainless’ is chromium; however it is the addition of nickel that enables stainless steel to become such a versatile alloy. It is the addition of nickel that enables stainless steel to become such a versatile alloy.
