Inspection & Test

When Analyses provide the Solution   

A good and thorough analysis requires knowledge and the right tools, and Damstahl’s Technical Consulting offers both. As part of this, we posses equipment making us able to perform non-destructive testing, such as measurements of the surface roughness and alloy testing with the help of XRF/PMI equipment.

The portable analyses are a great way of saving time and money. The use of the portable can be anything from a simple separation of a number of steel samples to more complex documentation tasks.

A fruitful collaboration in between Damstahl and The Technical University of Denmark proves us with the opportunity of performing more complex analytical tasks. Only the fantasy sets the limit.

XRF/PMI Analysis

The portable XRF/PMI equipment is a non-destructive method, capable of determining the chemical composition of stainless steel. In a matter of seconds, the PMI can detect all the most important elements in the steel and thereby determine the appropriate standard. Hereby, it’s easy to see if the steel belongs to the “common” 4301 class, the “acid resistant” 4401 class, any of the ferritic stainless steel grades and much more.

All this makes the PMI very well suited for classification of a large number of steel samples. And, as the XRF/PMI equipment is connected to a printer, adhesive labels may be printed on the spot.

Stereo Microscope

A key point within any corrosion inspection is the visible investigation of the specimen. To get very close, our stereo microscope is invaluable, permitting us to enlarge the picture between 10 and 40 times. In addition, it’s possible to make digital prints through the microscope – excellent for documentation.


Surface Roughness Measurements

A surface is not just a surface. Apart from the steel grade, the surface condition is often very important, and with the help of a Diavite surface roughness equipment, we are able to measure the surface roughness (as Ra, Rz and much more) on almost any specimen, including the outside and inside of tubes. Maximum and average values are calculated, and with the help of the printer, a profile of the surface can be generated.


Marking the Steel  

In many industries, traceability is a critical factor, and the marking of the charge or lot numbers is an important tool on the road to the required traceability. Normally, sheets, rods and tubes are all marked from the mill, however, it takes little cutting to end up with lots of pieces without the required numbers.

Using certified equipment, Damstahl’s Technical Consulting offers to mark the steel with the appropriate letters and numbers. This marking is permanent and is therefore the ideal solution in order to maintain the vital traceability.
