Laakeriteräsen

Laakeriteräsen, also known as bearing steel, is a specialized type of steel alloy primarily used in the manufacturing of rolling-element bearings. These bearings are critical components in countless machines and mechanisms, requiring materials that can withstand high loads, friction, and wear. The specific composition of laakeriteräksen is designed to optimize these properties.

The key alloying elements in laakeriteräksen typically include chromium, carbon, and often small amounts of other elements like molybdenum or vanadium. The high carbon content contributes to hardness, while chromium enhances hardenability, corrosion resistance, and wear resistance. The precise ratio of these elements, along with controlled heat treatment processes such as quenching and tempering, results in a material with excellent surface hardness and a tough, resilient core. This combination is essential for bearing performance, preventing premature failure due to fatigue, deformation, or surface damage.

Common grades of laakeriteräksen include those conforming to international standards like AISI 52100 (also known as 100Cr6 in some European standards) or JIS SUJ2. These steels are characterized by their ability to achieve high levels of hardness, typically in the range of 58-65 Rockwell C, while maintaining good toughness. The manufacturing process for laakeriteräksen involves careful control of melting, forging, and rolling to minimize impurities and ensure uniform grain structure. The exceptional durability and performance of laakeriteräksen make it indispensable for applications ranging from automotive components and industrial machinery to aerospace and precision instruments.
