Practical Considerations for Successful Hardness Testing
www.heat-treat-doctor.comHardness test-ing is one of the easiest tests to perform on the shop fl oor or in the laboratory, but it can be one of the hardest tests to do properly. Hardness is a property determined by measuring the resistance to deformation from an applied load. Alignment of the indenter to the sample surface is crucial to correct hardness measurements. The

iccontrols.com(0.125 inch) of scale thickness causes about 2 to 3 % boiler efficiency loss. Not only does it add directly to the fuel bill, but also the slowed heat transfer from hot gas to boiler water results in higher temperature in the tube metal, and possible tube failure, boiler outage, and costly repairs.
