Vertical 175mm Manual Loading Superficial Rockwell Hardness Tester with 0.5HR Resolution

Vertical 175mm Manual Loading Superficial Rockwell Hardness Tester with 0.5HR Resolution

Technical Specifications:

Brief Introduction:

iqualitrol iRock-433H Superficial Rockwell hardness tester is a popular-used hardness testing instrument to measure the superficial Rockwell hardness of the materials.

No need for 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.

iqualitrol iRock-433H can be easily operated and stable performance, therefore it is widely used.

Application:

Suitable for surface quenched steel, surface heat treating and chemical treating materials, copper alloy, aluminum alloy, sheet, zinc layers, chrome layers, tin layers, bearing steel and cold and hard casting etc.

Rockwell Test Principle:

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 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.
