teräslangan

Teräslanka is a Finnish term that translates to steel wire in English. It refers to a long, slender strand of steel that has been processed through a wire drawing die. This process reduces the diameter of the steel rod, making it thinner and more uniform in shape. Steel wire is a versatile material used in a wide array of applications due to its strength, flexibility, and durability.

The production of teräslanka typically begins with steel rods, which are then cleaned and coated, often with a lubricant, to facilitate the drawing process. The rods are then pulled through one or more dies with progressively smaller openings. This cold-drawing process increases the tensile strength and hardness of the steel. Depending on the intended use, the wire can be further treated through processes like annealing to soften it or surface treatments for corrosion resistance.

Common uses for teräslanka include reinforcing concrete (rebar), manufacturing springs, cables, ropes, and various mechanical components. It is also found in everyday items such as paper clips, staples, and fasteners. The specific properties of steel wire, such as its diameter, tensile strength, and surface finish, are tailored to meet the demands of its intended application. The term teräslanka encompasses a broad range of steel wire products.
