JB-300B Charpy Pendulum Impact Strength Tester
Metallic Materials Charpy Notch Impact Tester
The JB-300B Impact Testing Machine determines the impact resistance of metal materials under dynamic load conditions, evaluating material quality in high-stress environments. This semi-automatic testing machine features simple operation and high efficiency, with an automatic pendulum return system that prepares for subsequent tests using residual energy.
Technical Features
- Single supporting pillar structure with cantilever pendulum design (Type C pendulum hammer)
- Screw-fixed impact knife for easy replacement and maintenance
- Beam-type sample bearing system
- Integrated safety features including safety pins and protective fence
- Semi-automatic electrical control for pendulum lifting, impact, and return
- Compliant with GB/T3808-2002 and GB/T229-2007 national standards
