Maraging Steel 300

Maraging Steel 300 is a high-strength alloy made with a precise mix of elements. Called “maraging” steel because it gets its strength from a special aging process at roughly 500 °C. It contains 18.5% nickel, which provide toughness, and 9% cobalt, which raises hardness and stability. Around 4.8% molybdenum improve wear resistance, while titanium and small traces of aluminum help form strong particles during aging. Carbon, silicon, and manganese stay very low, keeping the steel clean and ductile, with iron making up the balance. This careful mix give the alloy its unique strength. If nickel or cobalt drops, toughness and hardness fall sharply, affecting performance. Parag Metals is among the trusted maraging 300 suppliers, offering this alloy to industries worldwide.

The physical features of Maraging Steel 300 make it stand out in tough applications. It has a density of 8.00 g/cm³, which ensure consistent weight and balance in critical parts. The melting point is about 1412 °C, giving it strong resistance to high heat without losing form. Along with its toughness, these values explain why the maraging 300 steel properties provide reliable performance even under heavy stress where regular steels may bend or weaken.

Heat treatment and machining of vascomax 300 are simple and effective. The alloy can be annealed at 1038 °C (1900 °F) after cold working and cooled in air without issues. Aging at about 482 °C (900 °F) boosts hardness and strength to peak levels. Hot working is possible in a wide range which make it flexible for forging and forming. Maraging 300 heat treatment ensures that the alloy reaches its full potential, giving industries an alloy that machines well, welds with ease, and responds reliably to tough conditions.

The mechanical strength of maraging c300 is one of its biggest advantages. It offers a tensile strength of about 1158 MPa, giving it exceptional load-bearing capacity. The yield strength reaches 1056 MPa, which means it resists permanent deformation under stress. Even with such high strength, it keeps an elongation at break of 12%, showing it can stretch without snapping. These properties make it a dependable choice for aerospace, tooling, and high-performance machinery.
