MA 300 | 1.6354 - Data sheet
1.6358 | UNS K93120 | AMS 6514
Maraging 300 is a cobalt-containing martensitic age-hardening steel that offers very high strength with moderate toughness. This steel is suitable for use at temperatures up to 450°C and maintains constant notch impact properties at temperatures down to -50°C. Maraging 300 has a martensitic microstructure in the annealed state and achieves its high strength through precipitation heat treatment at a relatively low temperature. Maraging 300 is used for highly dynamic components in aviation and aerospace, high-performance motorsports, and precision engineering.
