Differences in Processes for Different Materials

Carbon steel round bar: Hot rolling → cold drawing → annealing (optional) Rolling temperature, drawing deformation
Stainless steel round bar: Hot rolling → solution treatment → cold drawing → polishing Solution temperature (1050~1100ºC)
Tool steel round bar: Forging → annealing → fine grinding Forging ratio, annealing hardness control

Process Selection Points
Cost priority: hot rolling process is suitable for high volume and low precision requirements.
Precision priority: cold drawing + grinding process for high value-added products.
Performance priority: forging + heat treatment (e.g., tempering) to enhance mechanical properties.
