Metal Strength and Stiffness: What’s the Difference?

2016-3-22  All steel has approximately the same stiffness, but comes in many different strengths depending on the alloying metals used. Stainless steel comes in more than 100 grades which are created by adding alloys such as chromium, silicon, nickel, carbon, nitrogen, and manganese to impart properties such as heat resistance, strength, flexibility, and ductility.
