Why Choose Our HIC Steel Plates?
Engineered for Sour Gas Environments
Steel in contact with water containing H2S will corrode, producing hydrogen at its surface. H2S not only inhibits the formation of hydrogen gas, reducing the opportunity for it to escape, but promotes its absorption into the steel. At typical working temperatures below 200 degrees Celsius hydrogen atoms can become trapped causing embrittlement and ultimately cracking.

CarElso HIC Premium+
Brown McFarlane provides a complete range of CarElso HIC Premium+ plate tested for its resistance to hydrogen induced cracking (HIC) in wet H2S (sour service) environments. The plate is manufactured by Industeel (part of the Arcelor Mittal Group) and is guaranteed by them to have the following minimum properties:o Crack Length Ratio (CLR) less than 5 %
o Crack Thickness Ratio (CTR) less than 1.5%
o Crack Sensitivity Ratio (CSR) less than 0.5%The plate is tested to NACE TM 0284-03 Solution A and certified to EN 10204 3.2 (Lloyds). It is compatible with many of the world’s most stringent proprietary specifications including Petrobras N1706, Saudi Aramco 01-SAMSS-016, EEMUA 179, Axens IN-43, Shell MESC 74/125, and Shell DEP 31.22.10.32.
