teräsmateriaaleista

Teräsmateriaalit, commonly referred to as steel, are alloys primarily composed of iron and carbon. The amount of carbon typically ranges from 0.002% to 2.14% by weight. Carbon is the most common alloying element in steel, but other elements like manganese, chromium, vanadium, and tungsten are also added to improve properties such as hardness, strength, and corrosion resistance.

The production of steel involves the removal of impurities from iron ore and then the precise addition of carbon and other alloying elements. This process is usually carried out in a blast furnace or an electric arc furnace. The resulting molten steel is then cast into various shapes, such as billets, blooms, or slabs, which are further processed into finished products.

Steel's versatility stems from its wide range of properties, which can be tailored through adjustments in composition and heat treatment. It is known for its high tensile strength, durability, and impact resistance. These characteristics make steel an indispensable material in construction, automotive manufacturing, shipbuilding, tool making, and many other industries.

Different types of steel exist, categorized by their chemical composition and intended application. Carbon steels are the most common, with varying carbon content affecting their properties. Alloy steels contain specific amounts of other elements to enhance performance. Stainless steels, for instance, contain a minimum of 10.5% chromium, which provides excellent corrosion resistance. Tool steels are hardened and tempered for use in manufacturing tools. The continuous development of new steel alloys and production techniques ensures its ongoing importance in modern society.
