Hardness Testing

Hardness testing is one of the most common quick indicators of the state of your material strength. You’ll be provided with a hardness value in various scales in order to point to the current processing status of your material.

Our hardness testing lab performs:

  • Aluminum hardness testing
  • Steel hardness testing
  • Stainless steel hardness testing
  • Tool steel hardness testing
  • Copper hardness testing
  • Cast iron hardness testing

We perform testing for customers in the forging, casting, hot wrought, cold drawn, machining, automotive, aerospace, and surface treatment industries.

Hardness Testing Methods

Most production hardness testing is performed based on the same objective. A specific load is applied to a given indenter and the resistance the material has to its deformation is quantified as its hardness. When looking at the different types of hardness testing methods (Brinell testing, Rockwell testing, Knoop testing, Vickers testing), the difference in methods is often just a change in load or indenter. When choosing which test to use, the considerations should be where to test, the size of material, and the expected hardness.

Brinell Hardness Testing

Brinell testing will represent the largest “bulk” hardness of material. For this, larger samples with ample testing space is needed.

Rockwell Hardness Testing

Rockwell hardness testing will represent a more localized area in a sample and can be taken on smaller samples as well.

Vickers Testing & Knoop Testing

Vickers testing and Knoop testing methods are performed on even smaller samples and represent micro-size areas of given material. Click for more information on our microhardness testing.


Hardness Testing Lab Standards

Titan Metallurgy performs hardness testing to ASTM E10, ASTM E18, and ASTM E384 most commonly.

Rockwell Hardness Testing

Rockwell hardness testing is performed on a variety of metallic samples, varying in hardness ranges. Our Rockwell hardness tester applies a specific load to a sample through a tungsten carbide ball or diamond indenter and measures the effect on the sample material. Our machine measures the hardness on multiple Rockwell scales, including B, C and superficial. Tests are performed to common international standards such as ASTM E18 and ASTM A370.


Brinell Hardness Testing

Brinell hardness testing can be used on almost any type of metal. The test equipment applies a 3000kg load with a tungsten carbide ball to the sample being tested. The technician electronically measures the circumference of the indentation to determine the hardness number in HBW. Tests are performed to common international standards such as ASTM E10 and ASTM A370.
