Kaynak, Talaşlı İmalat, Parlatma, Isıl İşlem ve Soğuk İşleme

İşlemDetaylar
KaynakWelds with matching composition filler metals. Suitable methods include gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW).
İşlemeRequires sharp tools and proper cooling. Carbide tools are recommended for turning and milling operations.
ParlatmaAchieves good surface finish with mechanical methods like buffing and polishing wheels. Chemical polishing is also effective.
Isı tedavisiAnnealing at 870°C (1600°F) followed by water quenching improves ductility and removes residual stresses.
Soğuk çalışmaCan be cold worked to various degrees for shaping. Cold working increases strength and hardness.
