Pin Brinell STE Series Hardness Testers

Pin Brinell STE Series Hardness Testers

Overview

The STE Pin Brinell testers are the first Brinell hardness testers at a low price. The unique impact hardness method uses a shear pin to control the force applied by a hammer, so it significantly reduces the costs of getting started in Brinell testing. The indentation left after a test is measured with a Brinell scope, just like a standard Brinell, so the tester can be used on non-homogeneous metals and as-ground test surfaces. The kit comes with with everything needed for testing (except the hammer and carbide indenter if testing on high hardness materials) and includes a bag of 250 shear pins (one pin is required for each test). This pin system replaces the impact bar system, giving greater versatility, high accuracy and quick, easy indentations that can be made by anyone. 

 

Features

  • Low-price Brinell testing
  • Each shear pin is precisely tested twice for accurate load application.
  • Load accuracy is +/-1% of load - more accurate than competing models.
  • Tester can be verified on standard Brinell blocks from HB100 to 700 (higher ranges using optional carbide indenter).
  • Very portable for use almost anywhere
  • Comes with an 8x power Brinell scope. Higher resolution scopes available at additional cost

Operation

The operator inserts an impact pin (G) into the impact head (E) and presses the indenter against the pin, puts the impact head into the impact sleeve and puts it into the holder. The unit is placed on the test location and hit firmly with the hammer. The indentation in the sample is measured with the Brinell scope and a Brinell hardness result is read off the enclosed chart for the measured diameter. Prior to performing a second test the operator must remove the broken shear pin and push the indenter out of the shear pin hole, ready for the the next shear pin.

Product Update: Change with Pin Designation

The manufacturer has replaced the "F" type pins with the new "G" type pins. The “F” designation is no longer used because the manufacturer of the pins and material used to make them has changed. The pins are equivalent, but the reference sheet supplied with them is different. All pins function the same as long as used with the reference sheet supplied with each bag of pins.
