3. Manufacturing Techniques for Nickel Steel Coated
Creaciónnickel steel coated products involves four key steps. Each step is tailored to enhance the material’s properties:
3.1 Procesos de creación de acero
Primero, the base steel is made using:
- Horno de arco eléctrico (EAF): Melts scrap steel with electricity—fast and eco-friendly (utilizado para 70% of coated steel).
- Horno de oxígeno básico (Bof): Converts iron ore to steel—ideal for large batches (P.EJ., para cascos de barcos).
3.2 Tratamiento térmico
Heat treatment optimizes the base steel’s strength:
- Temple & Templado: Cools steel quickly (temple) then reheats (templado) to boost hardness without brittleness. Used for engine components.
- Recocido: Heats steel slowly to reduce stress—critical for forming parts like exhaust pipes.
- Endurecimiento por precipitación: Adds fine particles to the steel to increase strength (used for aerospace parts).
