JB-300 Manual Impact Testing Machine
The JB-300 manual impact tester is used to measure the resistance of metal materials to impact under dynamic load, so as to judge the quality of the material under dynamic load. This testing machine is hand-controlled, and the pendulum, impact and braking are controlled manually. It is suitable for ferrous metals with large impact toughness, such as the impact performance test of steel and its alloy materials. GB229-2007 “Metal Material Charpy Pendulum Impact Test Method”. This series of impact testing machines is the first choice for physical and chemical laboratories in metallurgy, boiler pressure vessels, steel, steel pipes, hardware, casting, pumps, valves, fasteners, vehicles and ships, machinery manufacturing, petrochemicals, aerospace and scientific research institutions. Impact equipment.
