Process Advantages and Material Selection Guidelines
Advanced high-speed rolling and controlled cooling technologies ensure dimensional precision (±0.1 mm) and microstructural homogeneity, supporting downstream processes like drawing and heat treatment. Material selection must comply with industry standards (ASTM, GB/T, JIS), prioritizing carbon content, elongation, and surface defect control.
