Macro evaluation of an Oil&Gas component

Macro image of a low alloy steel component intended for the Oil & Gas sector.

Macrograph evaluation of a mold component made of a low alloy steel intended for the Oil&Gas sector. Thanks to the macro etching it is possible to highlight the fiber flow and possible irregularities. 

Intergranular corrosion

Ongoing integranular corrosion tests at Kaizen Lab (ASTM A262 / ISO 3651-2)

Accreditation extension rev.6

Kaizen Lab is glad to announce the successful accreditation for the chemical analysis on low alloys, stainless steels, duplex stainless steels, ferritic/martensitic stainless steels and metallography and mechanical tests on welding.

Chromium nitrides in Duplex stainless steels

Chromium nitrides in the Duplex steels are a relevant detrimental chemical compound that affect fragility and pitting corrosion due to the reduction of Chromium inside the solution. The images show how important is the metallographic etching stage, because a generic etching does not enable the evaluation of the chromium nitrides. The metallographic ability and know-how of a laboratory is fundamental during the quality control and R&D stages.
