The product features uniform microstructure and high flatness, compatible with laser cutting processes, producing smooth cuts with minimal burrs. The annealed hardness is moderate, facilitating convenient stamping, bending, finishing, and subsequent heat treatment. After quenching, it achieves high hardness, good elasticity, and excellent wear resistance. Saw blades made from this material exhibit slow wear during high-speed cutting and outstanding anti-wear capability.
Product Applications
Circular saw blades, saw blade substrates, laser cutting materials, precision cutting tools, high-load springs, thin wear-resistant dies
