Steel Hardness Testing Machine

Rockwell hardness testing machines.

Steel hardness testing machine.

There are different scales denoted by a single letter that use different loads or indenters. The vickers hardness test was developed in 1921 by robert l. At united testing we offer a large selection of electromechanical as well as servo hydraulic universal test machines designed for testing steel and steel alloys. Shop here for rockwell hardness testers that can measure materials from soft bearing metals to carbides.

Our electromechanical test frames are rated from 2 5 kn up to 600kn. Annealed or normalized steel aluminum alloy copper alloy cast iron. The vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter and the indenter can be used for all materials irrespective of hardness. Hardness is a characteristic of a material not a fundamental physical property.

It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation. The rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter. Hardness symbol indenter type total test forcef n kgf hardness range applications. Hard alloy carbide shallow case hardening steel and etc.

The range includes portable units from proceq which are suitable for inspecting various materials. Smith and george e. You can rent a broad range of hardness testers from ashtead technology. The machine uses a minor load and a major load to make sure that the reading is accurate.

Portable leeb hardness tester gauge lcd digital rebound hardness measuring meter ls140 durometer testing scale for metal steel measure 270 00 270. This is probably the most common way of professionally and accurately checking the hardness of metals. A rounded steel ball or conical diamond tip is pushed into the metal and the depth of the indent is measured by the machine. The indenter is forced into the test material under a minor preliminary load and the permanent effect.

The rockwell test measuring the depth of penetration of an indenter under a large load major load compared to the penetration made by a preload minor load. Sandland at vickers ltd as an alternative to the brinell method to measure the hardness of materials. Brinell testers help you accurately test steel parts such as castings and forgings. Use a vickers tester to help assess the hardness value of small precision parts thin materials wires or case depth hardness.

Blue star e e provides a wide variety of high quality rockwell hardness testers.
