Steel Metallurgy: Properties, Specifications and Applications Jan 1, 2553 BE —

Steel metallurgy is the science of processing iron and carbon—often with other alloying elements—to achieve specific mechanical and chemical properties for engineering use. At its core, steel is iron containing less than 2% carbon, with the balance and arrangement of these atoms determining the material's final characteristics. Key Properties of Steel Selecting the right steel grade requires a deep

Increases toughness, particularly at low temperatures, and stabilizes the austenite structure.

Heating steel above its critical temperature and cooling it slowly in a furnace. This softens the metal, relieves internal stresses, and improves ductility. At its core, steel is iron containing less
