NDT Series Digital Display Drop Hammer Impact NDT Test Equipment
1.Application:
This machine is applicable for nil ductility transition temperature testing of ferrite steel.
NDT temperature is the highest temperature when the standard specimen is broke
according to the standard of ASTM E208-2006,GB/T 6803-1986.
Also means the highest temperature of the crack steel occurred brittle fracture under
dynamic loading yield stress.
2.Standards:
ASTM E208-2006,GB/T 6803-1986.
