Desta Steel is a major manufacturer and supplier located in Addis Ababa, Ethiopia. They are known to be the most notable point of reference when it comes to high-quality Carbon Steel EN-19 Bars. The precision engineering and top-line technologies utilized by Desta Steel not only guarantee but also highlight the supreme strength, long life, and impeccable performance of their products. Their EN-19 Bars are made to conform to the international quality standards, thus, they are the perfect choice for heavy industrial and engineering sectors’ applications. With a focus on trust, creativity, and consumer delight, Desta Steel goes on to deliver strong steel solutions that lead the way for Ethiopia’s expanding infrastructure and manufacturing industries.
Carbon Steel EN-19 Bars consists of the following elements: iron, carbon (0.35–0.45%), chromium (0.90–1.20%), molybdenum (0.20–0.40%), together with minor amounts of manganese and silicon. This favorable mix of components provides the product with outstanding tensile strength, good ductility, and great wear resistance. After being heat-treated, the material also gains additional toughness, fatigue strength, and hardness. Moreover, the stability under stress and the ability to be reliable in high-load and high-impact conditions make these materials excellent to be used in the field of mechanics and construction where they will be subjected to these kinds of conditions.

Carbon Steel EN-19 Bars are the prime choices that have been made by automotive, mechanical, and industrial sectors for the production of components that are tough and durable at the same time. There are many very typical applications of this kind of products, where they are for instance used to manufacture gears, shafts, axles, studs, crankshafts, and bolts. Apart from these bars, there are also many other applications like the heavy machinery industry, tool construction, and power transmission systems where the use of these bars has been extended. The outstanding mechanical characteristics of the product and its ability to adapt to heat treatment make them the perfect solution for those applications which experience high stress, high torsion, and impact, thus they will be able to provide long-term reliability and performance in these fields.
