Using Scopes:
● Rockwell Hardness Testing of Ferrous Metal,Non-ferrous Metalt and Non-metallic Material.
● Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging parts, hard alloy steel, aluminum alloy,bearing steel, carburized steel sheet, etc.
Feature:
● Easy to use, and the test force can be applied and unloaded by a handle;
● Dial direct reading, HRA, HRB, HRC scale;
● Other scales of Rockwell are optional;
● High precision of indication, easy installation and low failure rate

● A scale: It is suitable for testing the metal more than 70HRC, such as tungsten carbide, hard alloy as well as the hard sheet material and the hardening material on the surface layer.
● B scale: It is suitable for testing non-ferrous metals and alloys, annealing steel or soft or medium hardness of materials.
● C scale: It is suitable for testing the carbon steel, tool steel and alloy steel.

Great protection from super glue spills
Size: 11"×17" 20Sheets & 8.5"×11" 10Sheets, Color: Teflon Paper
I work a lot with super glue and found that these work very well when covering work surfaces. Super glue will not permanently stick the Teflon sheets and in most cases are reusable.

Worth the money
Size: 11"×17" 20Sheets & 8.5"×11" 10Sheets, Color: Teflon Paper
Works as stated however cut to just bigger than your ironon image. They aren't reusable. My images were on the paper so I didn't reuse. But they worked wonderfully
