Catering to industries like heavy machinery, fabrication, construction, and general engineering, Isis Metals offers both standard and tailored dimensions. Their commitment to durability, strength, and consistent performance has made them a reliable partner for businesses in need of carbon steel bars that can handle high stress and wear.
Carbon Steel EN Series Bars are made with different levels of carbon content, usually between 0.20% and 1.20%, along with elements like manganese, silicon, chromium, nickel, and other alloys, depending on the specific EN grade. These bars are known for their impressive tensile strength, yield strength, hardness, and toughness. They respond exceptionally well to heat treatment, which enhances surface hardness while keeping the core ductile and tough. While mechanical properties can differ across grades, EN Series bars generally offer strong wear resistance, fatigue strength, and dimensional stability, making them perfect for demanding engineering tasks.
