WebHR15T can be represented as Rockwell Superficial 15-T Scale. The Rockwell Superficial Hardness Tester is used to test thin materials, lightly carburized steel surfaces or parts that might bend or crush under the conditions of the regular test. This tester uses the same indenters as the standard Rockwell tester but the loads are reduced. http://www.iron-foundry.com/hardness-hrc-hrb-hb.html
