Home > Maraging Steel Bar
Mumbai, India-based Jyoti Steels is a prominent manufacturer and supplier of high-performance Maraging Steel Bars, designed to provide superior strength, toughness, and dimensional stability. Focused on precision and international quality standards, Jyoti Steels caters to critical sectors such as aerospace, defense, tooling, and automotive. Maraging steel bars from Jyoti Steels are characterized by low carbon levels, high weldability, and resistance to crack growth and thus are best suited to high-stress applications requiring reliability and long life under severe mechanical loading.
Maraging Steel Bars are generally made up of Nickel (Ni) 17–19%), Cobalt (Co) 8–12%), Molybdenum (Mo) 3–5%), and minor amounts of Titanium (Ti) 0.1–0.5%), Aluminum (Al) 0.05–0.15%), and Carbon (C ≤ 0.03%). Such bars have extremely high tensile strength (upto 2000 MPa) and yield strength more than 1500 MPa, with elongation ranging from 6–15%, based on heat treatment. The density is around 8.0 g/cm³, and they provide superior dimensional stability, low thermal expansion, and high hardness following aging. They can be accurately customized through heat treatment, suitable for high-precision, fatigue-resistant parts.
