          2025-08-01

          The Impact Test Steel Ball is mainly used to determine the shell mechanical strength of appliances. The shells of the appliances should be sure that it can not appear the danger within the scope of the standard ranges when operating.it is suitable for the appliances which surfaces of shells are damaged and will contact with the hazardous parts, and also suitable for testing mechanical strength of glass,PVC ,ceramics and so on.

          The specification of the impact test steel ball:

          weight

          tolerance

          material

          hardness

          227g

          ±5%

          G20CrNi2Mo

          HRC68-75

          500g

          ±5%

          G20CrNi2Mo

          HRC68-75

          535g

          ±5%

          G20CrNi2Mo

          HRC68-75

          1040g

          ±5%

          G20CrNi2Mo

          HRC68-75


          2,Method of Application

          Lift the steel ball up to the appropriate height , perpendicular to the sample surface,and then release the ball impact samples.

          Energy(J)=weight (kg)*gravity acceleration*high(m) the following table g =9.783

          3,Note:

          ■ The steel ball needs to be coated anti-rust oil to storage after

          testing

          ■ Pay attention to protection work to prevent injury when testing.

          ■ Please put on protective goggles when testing the fragile

          Sample.
