At Black Metallic LLP SP, we perform case hardening of metallic components up to 50 HRS and 0.060” using induction hardening. This method quickly and selectively hardens the surface of a metal part by placing a copper coil carrying a significant alternating current near the part, generating heat through eddy currents and hysteresis losses. The part is then quenched, typically with a water-based solution, transforming the structure into martensite, which is significantly harder than the previous structure.

Key benefits of Induction Hardening:

• Increased strength and wear life of parts with minimal distortion.
• Ability to adjust hardness levels through tempering after induction hardening.
