HIC Resistant Steel Plate is been manufactured through the electric arc furnace with dephosphorisation, desulphurisation, ladle refining and vacuum degassing to offer a homogeneous and ultra clean and steel. They offers specific and superior properties for sour gas application. HIC Resistant Steel is carbon steel which is tested to HIC Resistant Steel Chequered Platenstrate the plate’s resilience to the long term effects of hydrogen induced cracking, tested according to NACE. It is especially suited for pressure equipment where wet H2S corrosion can be a problem. HIC Resistant Steel Plate is most common grades of is ASTM/ ASME SA516. They are commonly certified to 60, 65 and 70 grades so one plate can fulfill the demands for any of the three grades A516 60/65/70 + HIC.
HIC Resistant Sheet is the ideal choice for pressure vessels and boilers as it is tested for resistance against hydrogen induced cracking. They are common to the oil and gas Industry, refineries and pipelines of petroleum and natural gas in wet hydrogen sulfide environments can be expected where the use of steel pressure vessels is widespread, the risk of this should be considered when hydrogen sulphide partial pressure becomes greater than 3.5mbar. As they are considered to be the most cost effective and sensible solution, since carbon steel plate standard is more liable to hydrogen sulphide corrosion.
