【 Construction steel pipe scaffold http://www. atjsj。 com/products- 细节。 asp吗? cpid = 14】 Steering fastener main advantage is hardness, strength and toughness is higher. The main has the following advantages: 1. Hardening layer martensite structure is fine. Ability to resist fatigue breaking workpiece is higher. 2. Profiles have great compression stresses in the workpiece surface after quenching. Workpiece deformation is small. 3. Do not need to whole heating. Power consumption is small, rotating fastener pollution-free. Workpiece profile oxidation decarburization is lighter. 4. Heating speed. Easy to realize mechanization and automation. 5. Heating equipment can device in mechanical processing production line. Convenient for management, and can reduce the transport, saving manpower, improve the production efficiency, easy to control.
