For identifying heat-treated from non-heat-treated parts
Provides correlation between a bench-mounted hardness tester and the production line
For identifying parts made from improper or substandard alloys. Checking for proper heat-treatment response
For identifying parts made from improper or substandard alloys.
Useful in conjunction with stationary laboratory hardness testers. It gives a rapid 100% check on parts which would consume many person-hours with slower operating test equipment
