Steel Vs. Iron Properties
Steel is stronger than iron (yield and ultimate tensile strength) and tougher than many types of iron as well (often measured as fracture toughness). The most common types of steel have additions of less than .5% carbon by weight. Higher percent carbon additions, while increasing strength, will cause the steel to become brittle. Other elements commonly found in steel are manganese, silicon, phosphorus, and sulfur. The class of steels called “alloy steel” may also have additions of nickel, chromium, molybdenum, and vanadium. Stainless steel is a popular low carbon content steel that contains chromium. Each added element, even in small amounts, contributes additional desirable properties to the steel alloy. When the recipe for the steel alloy is controlled and the material is processed correctly, an alloy consisting mostly of iron becomes one of the most useful materials ever invented.
What is the deal with magnetic Stainless Steel?
The theory of the “magnet test,” is sort of this rumor going around in which you’re supposed to test the quality of the stainless steel with a magnet. But really what this tests for, is whether or not the steel is austenitic, or made of a metal alloy which contains chromium and nickel.
