The company is committed to delivering materials that meet strict international quality standards, ensuring exceptional durability, toughness, and dimensional stability. With advanced production capabilities and a focus on customer satisfaction, Olwan Nickel Alloys provides Maraging grade sheets and plates that perform reliably in aerospace, defense, tooling, and engineering environments. Their dedication to quality, timely delivery, and technical expertise makes them a trusted source for advanced alloy materials.
Maraging 250, 300, and 350 Sheets and Plates are iron-nickel alloys enriched with elements like molybdenum, cobalt, and titanium, achieving ultra-high strength through age-hardening rather than carbon content. These grades offer remarkable tensile strength, excellent toughness, and reliable ductility, even after heat treatment. They display outstanding fatigue resistance, superior hardenability, and good weldability. Maraging steel also maintains exceptional dimensional stability under heavy loads and elevated temperatures. The combination of strength, durability, and predictable performance makes these sheets and plates ideal for high-stress, precision-engineered applications.
