DETAILED INFORMATION
As medium carbon steel, EN8 round bar has a high elasticity compared to ordinary mild steel, making it ideal for applications that require an advanced strength level, including tubes, studs, bolts, connecting rods, screws, rollers, etc. This type of steel is suitable for all types of manufacturing applications.
The EN8 bright bar is a medium-power mild steel appropriate for general manufacturing that demands higher power than mild steel. It has better superiority than EN3 but is less seamlessly machined than EN3. It can be used for tubes, studs, screws, and keys.
In addition to being an unalloyed medium carbon steel, EN8 round bar, also known as 080M40, is also used to produce products with better performance than mild steels in various applications. Heat-treating EN8 bright bars with flame or induction hardening processes can provide the bars with suitable surface hardness and moderate wear resistance.
En8 round bars are manufactured at Tri Alloys, the largest supplier in the country. We are a trusted exporter of EN8 round bars with our robust infrastructure in India. Based on various conditions of diverse mixed industries, this stockist of EN8 Round Bars in India offers a combination of good grades, thicknesses, lengths, and surface finishes. Additionally, Sagar Steel Corporation is one of India’s leading manufacturers of round bars.
En8 is a pure medium carbon steel with increased strength compared to regular mild steel. As popular steel in the industry, EN8 steel is ideal for manufacturing tubes, studs, bolts, linking rods, screws, rollers, and others that require high strength.
As with EN19, steel EN8 is a steel alloy that falls under engineering steel alloys. EN8 steel is medium carbon steel. Although unalloyed, the EN8 Carbon Steel Round Bar is estimated to contain between 0.60% and 1.65% manganese. The elemental carbon content of the 080M40 Hex Bar is between 0.30% and 0.60%, which is similar to what is typically found in carbon steels. The tensile properties of the alloy are moderate, as with most carbon steels, because they contain between 0.30% to 0.60% carbon. Even so, the Carbon Steel EN8 Flat Bar does exhibit properties such as flexibility and toughness to a decent degree. Because the alloy is malleable, it can be formed into unusual shapes such as hexagonal bars or hex bars much easier due to its elasticity. EN8 Bright Bars also exhibit low hardenability. Many of these alloys are heat treated to increase their mechanical properties.
EN8 Rod Suppliers will likely stock products that have been normalized or rolled. This medium carbon steel has a much lower carbon content than its high carbon counterpart, making it easier to weld than the high carbon steel version. A mild steel bar, on the other hand, has a slightly higher carbon content than an EN8 steel bar. However, the higher carbon content in the alloy makes the EN8 Round Bar durable so that it can be used in engineering to achieve a good result. For businesses in the construction of shafts or axles, EN8 Square Bar Suppliers stock these rods or bars of this alloy for firms to use in the construction of shafts and axles.
