Characteristics Of Cold-drawn Hexagonal Steel
Jan 20, 2025
The main characteristics of cold-drawn hexagonal steel include high strength and hardness, excellent mechanical properties, high dimensional accuracy, good surface quality and plasticity.
High strength and hardness: The cold drawing process refines the grains inside the steel, thereby improving the strength and hardness of the material. Compared with hot-rolled steel, cold-drawn hexagonal steel has higher tensile strength and bending strength, and can withstand greater force and pressure.
Excellent mechanical properties: The mechanical properties of cold-drawn hexagonal steel are significantly improved, with better wear resistance, fatigue resistance, toughness and ductility. These characteristics enable it to maintain stable performance in various complex stress environments.
High dimensional accuracy: During the cold working process, through multiple passes of drawing and rolling, cold-drawn hexagonal steel can obtain higher dimensional accuracy, regular cross-sectional shape, clear edges and corners, small dimensional deviation, and can meet more stringent dimensional requirements.
Good surface quality: The surface of cold-drawn hexagonal steel is smooth and flat, without wrinkles, cracks or other defects. It can be used directly without surface treatment. This feature makes cold-drawn hexagonal steel widely used in the manufacture of precision parts and projects requiring high surface quality. Good plasticity: Cold-drawn hexagonal steel has good plasticity and ductility, which is convenient for subsequent processing operations such as cutting, welding, and stamping. This feature reduces the difficulty and cost of processing, and also provides designers with more diverse design options. Diverse shapes: The cold drawing process can produce various shapes of special-shaped steel, including hexagonal, to meet the needs of special-shaped steel pipes in different fields.
