MACHINING

To ensure durability and resistance, we apply the following heat treatments according to the specific requirements of each component:Case Hardening (Carburising) → Increases surface hardness by adding carbon to the steel’s outer layer, while maintaining core toughness.Nitriding → Introduces nitrogen into the steel surface, enhancing wear and corrosion resistance without requiring post-hardening.Austempering → Provides high toughness and impact resistance by cooling the steel at an intermediate temperature in a salt bath.Martempering → Similar to conventional quenching but reduces internal stresses by controlling the cooling process before final hardening.

- Conventional Quenching (Full Hardening) → Steel is heated above the critical temperature and rapidly cooled (water, oil, or air). Advantage: High hardness throughout the component. Risk: Internal stresses may cause cracks.- Surface Quenching (Induction or Flame Hardening) → Only the surface is heated and rapidly cooled. Advantage: High wear resistance without compromising core toughness. Application: Gears, shafts, crankshafts.- Martempering  → Controlled cooling in a hot bath, followed by air cooling. Advantage: Reduces stresses and prevents cracking. Application: Thick components requiring high impact resistance.- Austempering → Intermediate cooling to form bainite (instead of martensite). Advantage: High toughness and impact resistance. Application: Springs, blades, gears exposed to impact.- Direct Quenching → Steel is heated and directly quenched in the cooling medium. Advantage: Simple and efficient process. Application: Tools and mechanical components.- Interrupted Quenching → Initial rapid cooling, followed by slower cooling. Advantage: Reduces brittleness and internal stresses. Application: Thick-walled components.- Isothermal Quenching → Steel is held at a constant temperature before final cooling. Advantage: Improved balance between hardness and ductility. Application: Structural components requiring strength and flexibility.
