Isis Metals stands out as a top manufacturer and supplier of Maraging Steel Bars and Rods, proudly based in Manila, Philippines. The company is dedicated to crafting high-quality, high-strength steels that are renowned for their remarkable toughness, dimensional stability, and resistance to wear and fatigue. Using cutting-edge metallurgical techniques and top-notch raw materials, their Maraging Steel Bars and Rods adhere to international standards for precision, durability, and performance. Isis Metals offers these bars and rods in a variety of sizes and finishes, catering to industries like aerospace, defense, tooling, automotive, and high-performance engineering, where exceptional mechanical properties are a must.
These Maraging Steel Bars and Rods are primarily made of iron, containing 18–25% nickel, along with trace amounts of cobalt, molybdenum, titanium, and aluminum. This unique blend gives the alloy impressive tensile strength of up to 2000 MPa, remarkable hardness (up to 60 HRC after aging), and outstanding toughness and ductility. The innovative maraging process allows the steel to achieve high strength without a significant carbon content, which reduces brittleness and enhances machinability and weldability.
