High Dimensional Precision
The cold - rolling process involves rolling steel at room temperature, enabling more precise control of the dimensions and shape of H - section steel. The dimensional tolerances of its products, such as thickness and width, are relatively small, and it can meet application scenarios with high requirements for dimensional precision, such as precision machinery manufacturing and automobile manufacturing fields.
Good Surface Quality
During the cold - rolling process, the steel surface is squeezed and rubbed by the rolling mills, resulting in a lower surface roughness, making it smoother and flatter with better appearance quality. At the same time, cold - rolling can also eliminate surface defects generated during the hot - rolling process, such as oxide scale and pits, improving the surface finish of the steel, giving it better corrosion - resistance and decorative properties. It is suitable for some occasions with strict requirements for surface quality, such as building decoration and home appliance manufacturing.
Higher Strength and Hardness
During the cold - rolling process, the steel undergoes plastic deformation and a work - hardening phenomenon occurs, increasing the strength and hardness of cold - rolled H - section steel. The yield strength, tensile strength and other indicators are better than those of hot - rolled H - section steel of the same material. It can bear greater external forces and loads and is widely used in some structural components with high strength requirements, such as bridges, cranes and industrial storage racks.
Good Machinability
Cold - rolled H - section steel has good machinability and is easy to carry out processing operations such as cutting, bending, stamping and welding. It can be processed into parts of various shapes and sizes according to different design requirements, meeting diverse production needs, improving production efficiency and product quality. It is widely used in machinery manufacturing, automobile manufacturing, building structure and other industries.
