Chemical element that in steel forms carbides that can reduce the hardenability if the temperature is not high enough to dissolve them. It prevents grain growth in heating, so it improves toughness and provides steel with great resistance to overheating. It is used in spring steels and non-deformable steels and high-speed tool steels.
Details Test that allows to measure the hardness of the material and determines the lateral surface of the indentation. It is used to measure the depth of coatings of outer layers or small section pieces. To perform the test, a square-based diamond pyramid is used as the indenter. The Vickers hardness is determined by: HV =…
Details Chemical elements contained in the steel and that have not been intentionally added. Residuals are mainly elements that come from the scrap that cannot be eliminated through the metallurgical process. They must be controlled by scrap clasification, since they can affect steel properties such as strength and specially plasticity.
Details Resistance that a material has to lose material on its surface due to a mechanical action (abrasion, erosion, adhesion, etc.)
Details Ability of a material to be joined by welding. Steels present greater weldability the lower the carbon content
Details This is a manufacturing process where two parts are joined by bonding. A metal or plastic filler material can be added that when melted, forms a pool of molten material between the parts to weld and when it cools, it becomes a fixed joint that is known as a bead.
Details Ability of a material to be joined by welding. Steels present greater weldability the lower the carbon content.
Details The steel wire is a product obtained by cold drawing from the wire rod. It is usually presented on reels.
Details Machining operation without chip removal consisting of the reduction of section of a wire or a rod making it pass through a conical hole practiced in a tool called die. Among the advantages of drawing we can find its good surface quality, dimensional accuracy, increased strength and hardness and the possibility of producing very thin…
Details Long product, which after the last hot rolling pass, is rolled up to form rolls with unordered turns. The section of the wire rod can be circular, oval, rectangular, hexagonal or other shapes. Its surface is smooth and the nominal measurement, in general, is equal to or greater than 5mm. Its most common applications are…
