The hardness of Rockwell hardness of the desktop, using Rockwell (ROCKWELL)
measuring principle, for carbon steel, alloy steel, cast iron, nonferrous
metals and engineering plastics materials, such as the hardness test, a test of
high precision, range wide, The main test of the automatic loading, measured in
figures
Show and automatically print or computer and external communications, and other
characteristics. Widely used measurement, machine building, metallurgy,
chemicals, building materials industries such as testing, research and
production.
The hardness of a special pressure head structure (commonly known as
"convex nose" structure), in addition to a traditional Rockwell
hardness to complete the tests, may also test the traditional Rockwell hardness
of the surface can not be measured, such as Central - Shaped, tubular, and
