Rockwell hardness for steel in HRC

Rockwell Hardness Testing (HRC): Portable or Benchtop? Choose the Precision That Suits You

Rockwell scale for hardness testing measurements, like HRC, can vary according to the choosen instrument

When it comes to quality control and determining the hardness of materials, the Rockwell hardness tester is an indispensable instrument in many industrial sectors.

But which version should you choose: portable or benchtop? The answer depends on the specific needs of your production process.

Portable Rockwell Hardness scale: The freedom to test anywhere

This portable test method offers great flexibility, allowing you to perform Rockwell tests directly on the production line, in the warehouse, and is particularly useful for on-site inspections.

Consider the Oil&Gas sector, for example, which requires periodic checks directly on pipes and fittings due to the corrosive environments to which these products are subjected.

The hardness measurements can be expressed in various scales, including Rockwell (Rockwell C scale, Rockwell B, etc.), as well as Brinell and Vickers.

 Its portability makes it ideal for:

  • Controls on large objects, that are generally impossible to test with a traditional benchtop hardness tester.
  • On-site tests: for detecting the superficial hardness of metallic materials of components directly within assemblies or structures that cannot be moved.
  • Field inspections for durability checks: evaluating the condition of materials and components under operating conditions.

When to choose a portable tester

MOBILITY

You need a lightweight and easy-to-transport tool to measure any material (steel, bronze or harder materials).

SPEED

Test execution speed is your priority.

NON-CRITICAL APPLICATIONS

Absolute precision is not a fundamental requirement for your quality control.

Benchtop Rockwell Hardness: Absolute Precision and Repeatability

Unlike its portable counterpart, the benchtop hardness tester is designed to offer the highest level of precision and repeatability.

 Its robust structure and the presence of ergonomic and stable clamping systems guarantee highly reliable results, fundamental for critical applications that generally require meeting rigid final performance regulations. This is a must in metallurgy.

Consider the UNI EN 9100, an essential standard for those working in the Aerospace sector, which guarantees excellent quality throughout the entire production chain to ensure a final product performance declared by many companies as “zero defects.”

Its irreplaceable reliability makes it ideal for:

  • Highly accurate measurements: human influence on tests is reduced to zero, because the calculation of the depth of penetration of an indenter (diamond cone) given by the difference between an minor load followed by a major load is machine-controlled. This does not happen with the portable counterpart.
  • Repeatable results: perfect for creating reference databases for statistical analysis of different materials like hardened steel or softer metallic sample.
  • Compliance with international standards: ensures traceability of hardness values and compliance with ASTM and ISO standards.

Rockwell bench hardness tester AXE440-B

When to choose a benchtop indentation hardness tester

YOU NEED HIGH PRECISION

Extremely accurate and reliable measurements are essential for you to comply with your industry’s reference standards

YOU NEED TO ANLYZE THE RESULTS OBTAINED

(e.g. Rockwell B scale) through a 4.0 integration.

CRITICAL SECTORS

You have to measure the hardness in sectors such as automotive, aerospace, or medical, where quality is essential to meet demanding product performance requirements.

If you work in a sector where precision and compliance are essential requirements, the Rockwell hardness tester AXE440-B is the ideal solution. This benchtop instrument, thanks to its advanced features, allows you to:

Determine the hardness of a wide range of materials

Obtain rapid, precise results, and above all, with a high repeatability index for any Rockwell scale

Conform your processes to the most rigorous quality standards

Rockwell b and c scale results that are so repeatable they seem unreal

Request our free “Test & Report” service: send us your small samples and we will provide you with a detailed report with the test results carried out with our AXE440-B hardness tester.

You can thus experience firsthand the precision and reliability of this instrument.

The sample material can be of any metallic composition, like hard steel or softer steel, copper, alloyes etc. The test report can be performed for any scale like rockwell C hardness scale or more superficial rockwell scales. Obviously it deals with NDT tests (non destructive tests), so your sample will not be broken.
