Each batch of Mainlywell lifting rings provides you with four layers of |
1. Raw material inspection: Scientifically adjusting the proportion of alloy elements in raw materials through metallographic analyzers to ensure strength and toughness. 2. Magnetic particle inspection test: After heat treatment processing, metal forgings are subjected to magnetic particle inspection testing. |
3. Fatigue resistance test: Before leaving the factory, it must pass 20,000 dynamic fatigue tests at 1.5 times the working limit load. 4. 4x tensile test: Before leaving the factory, a tensile test must be conducted with a factor of 4 times the working limit load, and the deformation should not exceed 1%. |
