CromElso® 22 is a low alloyed Cr-Mo steel designed for pressure equipment such as hydrotreating reactors operating at elevated hydrogen pressure and temperature. CromElso® 22 is manufactured via the electric arc furnace with dephosphorisation, ladle refining and vacuum degassing to provide reproducible, clean and homogeneous steel.

The use of special steelmaking practice with extra- low phosphorus levels gives CromElso® 22 improved resistance to temper embrittlement, as well as providing excellent low temperature impact toughness properties.

CromElso® 22 is particularly suitable for pressure equipment in high temperature hydrogen service (e.g. hydrotreating reactors, exchangers). This steel is available in plate form in thickness up to 250 mm, and can also be provided in mono- or multi-piece heads.
