Teräsjousia

Teräsjousia, commonly known as steel springs, are elastic mechanical devices made from steel that are designed to store mechanical energy when deformed and release it when the deforming force is removed. They are ubiquitous in countless applications due to their ability to absorb shock, dampen vibrations, and exert force. The primary material used is spring steel, a type of steel alloy with high yield strength and elasticity, often containing elements like silicon, chromium, vanadium, or manganese to enhance its properties.

The manufacturing process typically involves shaping steel wire, rod, or flat strips into various forms. Common types include coil springs (like compression, tension, and torsion springs), leaf springs, and flat springs. The specific design and dimensions of a steel spring are crucial for its performance, determined by factors such as the material's properties, the geometry of the spring, and the intended load or motion. Heat treatment, such as quenching and tempering, is a critical step in achieving the desired hardness and resilience in the spring steel.

Steel springs are essential components in industries ranging from automotive (suspension systems, valves) and aerospace to consumer goods (mattresses, pens) and industrial machinery. Their ability to withstand repeated stress cycles without permanent deformation makes them highly durable and reliable. The design and selection of the appropriate steel spring are vital for the optimal functioning and safety of many mechanical systems.
