MIM-LD-G19
MIM LD-G19 is Jingye Lide's proprietary ultra-high-strength maraging steel. Based on a carbon-free (or micro-carbon) martensitic matrix, it achieves strengthening through age-hardening precipitation of intermetallic compounds. The tensile strength exceeds 2000 MPa after post-heat-treatment, which makes it one of the highest-strength grade among MIM materials at present. And it is designed for aerospace, high-end equipment, and applications demanding extreme strength.
