The Maraging 250/300/350 Sheets and Plates are ultra-high-strength steels, primarily alloyed with nickel, along with cobalt, molybdenum, and titanium. This unique composition allows them to achieve exceptional strength through age-hardening instead of relying on carbon. Maraging 250 is known for its high toughness and good ductility, while Maraging 300 steps it up with increased tensile strength and fatigue resistance. Maraging 350 stands out as the strongest of the trio, boasting superior hardness and impact resistance. All three grades are characterized by excellent fracture toughness, dimensional stability, and weldability. They maintain their mechanical properties even at elevated temperatures and show remarkable resistance to stress cracking, making them ideal for heavy-duty engineering applications.
