Steel is an alloy of iron and carbon, widely used in industry for its mechanical properties, strength and versatility.
Definition of steel
L’steel is a metal alloy consisting mainly of iron and carbon (less than 2 %). The addition of carbon considerably improves mechanical strength and hardness compared to pure iron.
Types of steel
- Mild steels low carbon content, easy to weld and work.
- Alloy steels addition of elements such as chromium, nickel or manganese.
- Stainless steels corrosion-resistant thanks to chromium.
- Special steels refractory, tool or high-strength steels.
Properties
- Mechanical resistance high.
- Ductility and malleability.
- Solderability variable according to composition.
- Durability in controlled environments.
Industrial applications
Steel is omnipresent in industry:
- Building structures, metal frameworks.
- Transport automobiles, ships, aircraft.
- Energy pipelines, turbines, power plants.
- Tools machines, molds, cutting tools.
