Brief Introduction:
iqualitrol Vexus SHR-150M Rockwell hardness tester is a popular-used hardness testing instrument to measure the hardness of the metal materials.
iqualitrol Vexus SHR-150M does not need power supply, the speed of the test force loading is regulated by the buffer and the test force is regulated by the load-change hand wheel. It has easy operation and stable performance, therefore it is widely used.
Application Range:
Suitable for quenched steel, tempered steel, annealed steel, cold and hard casting, malleable cast iron, hard alloy steel, aluminum alloy, copper alloy, bearing steel etc. Also suitable for surface quenched steel, surface heat treating and chemical treating materials, sheet, zinc layers, chrome layers, tin layers etc.

Principle of Rockwell Test:
The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).
The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.
The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with iqualitrol 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low numbers soft materials.

Rockwell Hardness Scales:
| Scale Symbol | Indenter | Test Force (Kgf) | Dial Figures | Typical Application of Scales |
| HRB | 1/16” Ball | 100 | red | Copper alloys, soft sheets, aluminum alloys, malleable iron, etc. |
| HRC | Diamond | 150 | black | Steel, hard cast irons, pearlitic malleable iron, titanium, deep case hardened steel, and other materials harder than B100. |
| HRA | Diamond | 60 | black | Cemented carbides, thin steel, and shallow case-hardened steel. |
| HRD | Diamond | 100 | black | Thin steel and medium case hardened steel, and pearlitic malleable iron. |
| HRE | 1/8” Ball | 100 | red | Cast iron, aluminum and magnesium alloys, bearing metals. |
| HRF | 1/16” Ball | 60 | red | Annealed copper alloys, thin soft sheet metals. |
| HRG | 1/16” Ball | 150 | red | Malleable irons, copper-nickel-zinc and cupro-nickel alloys. Upper limit G92 to avoid possible flattening of ball. |
| HRH | 1/8” Ball | 60 | red | Aluminum, zinc, lead. |
| HRK | 1/8” Ball | 150 | red | Bearing metals and other very soft or thin materials. Use smallest ball and heaviest load that does not give anvil effect. |
| HRL | 1/4” Ball | 60 | red |
| HRM | 1/4” Ball | 100 | red |
| HRP | 1/4” Ball | 150 | red |
