Avoid problems caused by too hard carbon steel

Hardness Testing is a quick reliable way of measuring the hardness of carbon steel. This is important, because if a carbon steel alloy is too hard, it will typically also be quite brittle and more prone to rupture. And this will obviously lead to higher repair costs as well as unsafe situations.

NDO Nederland conducts an indicative hardness test on-site, allowing construction to be not or very little delayed. An advisory report is also always included, allowing you to avoid similar future problems.

  • Always quick results due to on-site testing
  • Preventing high costs and unsafe situations
  • Guaranteed proper carbon steel hardness
  • Advisory report always included

Advantages of Hardness Testing

The main advantage of Hardness Testing by NDO Nederland is a 100% guarantee that the used carbon steel isn’t too hard, thus reducing the risk of brittle fractures or ruptures. This also prevents high repair costs and unsafe situations.

Thanks to our advanced testing equipment is it also possible to conduct indicative measurements on-site. Only after the results of this measurement exceed certain limits, we will conduct a test on a stationary testing unit. This portable testing offers much quicker and easier results, than when only stationary measurements are the only option. Construction delay can thus be avoided in many cases.

  • Guaranteed proper carbon steel hardness
  • Preventing high costs and unsafe situations
  • Testing on-site also possible

How does Hardness Testing work?

We often see too high levels of hardness occur when pre-heating procedures during welding are not followed properly. Do you want to make sure that the carbon steel meets all requirements? Have a hardness test conducted. This type of non-destructive testing prevents possible repair costs and ensures a safe end product.

Maximum limit levels of carbon steel hardness are stipulated in various standards, legislations and specifications. A hardness test will allow you to determine in time whether the used material meets the requirements. NDO Netherlands uses the Equotip hardness test in which units such as Vickers, Rockwell and Brinell are often used.
