Teräslajikkeina

Teräslajikkeina refers to different types or grades of steel, each possessing distinct properties that make them suitable for specific applications. The classification of steel is typically based on its chemical composition, particularly the percentage of carbon, and the presence of alloying elements.

Carbon steel is the most common type and is classified by its carbon content. Low-carbon steel, with less than 0.25% carbon, is ductile and easily formed, used for general purposes like construction and automotive parts. Medium-carbon steel, containing 0.25% to 0.60% carbon, offers a balance of strength and ductility, suitable for machinery parts and railway tracks. High-carbon steel, with over 0.60% carbon, is very hard and strong, used for tools, springs, and high-wear applications.

Alloy steels incorporate other elements like chromium, nickel, molybdenum, and vanadium to enhance specific properties. Stainless steel, a prominent alloy steel, contains at least 10.5% chromium, providing excellent corrosion resistance. Tool steels are a group of alloy steels designed for high hardness, wear resistance, and toughness, often used in cutting tools and dies.

The selection of a specific teräslajikkeina depends on the required mechanical properties such as tensile strength, hardness, toughness, and resistance to corrosion or heat. Each type is manufactured through controlled processes to achieve its intended characteristics, playing a crucial role in various industries from manufacturing and construction to aerospace and healthcare.
