Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, is all about crafting top-notch Carbon Steel EN-42 Bars that are built for strength, durability, and precision. With cutting-edge manufacturing technology and strict quality control measures, Aung Metals guarantees that each EN-42 Bar not only meets international standards but also performs reliably in tough industrial settings. These bars are celebrated for their impressive tensile strength, hardness, and wear resistance, making them perfect for the automotive, mechanical, and general engineering sectors. Aung Metals delivers precision-engineered steel solutions that blend toughness, machinability, and long-lasting performance, making them the go-to choice for high-stress and heavy-duty components.
Carbon Steel EN-42 Bars are medium-carbon steels that contain about 0.38–0.45% carbon, 0.60–0.90% manganese, along with trace amounts of phosphorus and sulfur. This unique blend results in a well-rounded mix of hardness, strength, and toughness. On the mechanical side, EN-42 steel boasts a tensile strength of roughly 600–700 MPa and a yield strength of 350–450 MPa. It’s known for good machinability, moderate ductility, and outstanding wear resistance, plus it can be heat-treated to boost hardness and performance in demanding engineering tasks.
