                    What are the steel balls used in the laboratory?

                    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

                    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.

                    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.
