perusteräkseen

Perusteräs, also known as carbon steel, is a steel alloy where carbon is the primary alloying element. Its properties are largely determined by the carbon content, which typically ranges from 0.02% to 2.1% by weight. Higher carbon content generally leads to increased hardness and strength, but also reduced ductility and toughness.

Common grades of perusteräs are classified based on their carbon content. Low-carbon steel, containing less than 0.3% carbon, is ductile, easily formed, and weldable. It is widely used in construction, automotive parts, and general fabrication. Medium-carbon steel, with carbon content between 0.3% and 0.6%, offers a balance of strength and ductility and can be heat-treated to improve its mechanical properties. It finds applications in gears, shafts, and railway tracks. High-carbon steel, containing more than 0.6% carbon, is very hard and strong but brittle. It is used for cutting tools, springs, and high-strength wires.

Perusteräs is known for its affordability and versatility, making it a fundamental material in many industries. However, it is susceptible to corrosion, particularly in humid environments, and often requires protective coatings like paint or plating to prevent rusting. Its properties can be further modified through various heat treatments such as annealing, quenching, and tempering, allowing manufacturers to tailor the steel for specific performance requirements.
