Impact on processing performance
Cutting: When the hardness of Steel Strapping is high, the cutting difficulty will increase. For example, when using a saw blade to cut high-hardness Steel Strapping, the saw blade will wear faster, requiring greater cutting force, and it is easy to generate heat during the cutting process, which may cause local structural changes in the Steel Strapping and affect the cutting quality. Steel Strapping with moderate hardness is easier to cut and can obtain a neater cutting edge. In laser cutting, Steel Strapping with too high hardness may reflect more laser energy, reduce cutting efficiency, and may produce a hardened layer on the cutting surface.
Bending and forming: Steel Strapping with too high hardness is easy to break during bending. Because the outer side of Steel Strapping is subjected to tensile stress and the inner side is subjected to compressive stress when bending, high hardness means that the plastic deformation ability of Steel Strapping is poor and it cannot withstand large stress changes. On the contrary, Steel Strapping with lower hardness can better adapt to bending and forming operations, can bend at a smaller radius without cracking, and is conducive to the production of various complex-shaped parts. For example, in the stamping process of making automotive parts, Steel Strapping with appropriate hardness is crucial for successfully stamping out qualified products.
Welding processing: Steel Strapping hardness also affects welding. High-hardness Steel Strapping may require special welding processes because its internal structure is tight and it is difficult to fuse during welding. If the hardness is uneven, it may also cause stress concentration at the welded joint and reduce the welding quality.
Impact on performance
Wear resistance: Steel Strapping with high hardness usually has better wear resistance. In an environment that needs to withstand friction, such as the Steel Strapping skeleton in the conveyor belt, high-hardness Steel Strapping can maintain dimensional accuracy and surface quality for a long time, reduce wear and extend service life.
Load-bearing capacity: When used as a structural part, Steel Strapping with appropriate hardness can provide better load-bearing capacity. For example, in building steel structures, the hardness of Steel Strapping determines its deformation when subjected to gravity and other external forces. Insufficient hardness may cause the structure to deform prematurely, while excessive hardness may make the structure lack toughness and easily damaged when impacted.
