HIC Resistant Steel Plate

HIC (Hydrogen Induced Cracking) is the result of a corrosive reaction between carbon steel and hydrogen sulphide. Wet hydrogen sulphide (H2S) cracking in steel has been a problem in petroleum refining and upstream oil and gas processing since the 1950s. Working conditions where wet H2S prevails are often described as sour service conditions and the term sour gas can be also be used in this context. As more fields rich in H2S are exploited, and this is increasingly the case, the problem is increasingly significant for equipment fabricated in potentially sensitive carbon-manganese (C-Mn) steels.

The most common grades of HIC resistant steel plate is A516 – to ASME/ASTM standards. It will generally be certified to grades 60, 65 and 70 so one plate can meet the requirements for any of the three grades A516 60/65/70 + HIC. stancor supplies pressure vessel steel plates that are manufactured to be resistant to hydrogen induced cracking.With years of experience in Manufacturing Exporting, supplying HIC Steel Plate, we offer high quality, lower cost but the best service

 As a result to that our export account today is in over 45 countries some of them are in Iran, Saudi Arabia, United Arab Emirates, Singapore, Malaysia.we assured our client that we are standing behind our product which we have supplied as well as we issued a quality certificate along with our product which we manufacture supplies and exports

The most important thing to know as a potential customer of stancor is that we stock, process, and distribute all of the popular grades of Boiler and Pressure Vessel specifications like  A516 Grade 60 Steel Plate , A516 Grade 65 Steel Plate , A516 Grade 70 Steel Plate, ASTM A516 GRADE 60 65 70 Plates Trippled Certified , ASTM A516 GRADE 60 70 Plates Dual Certified, A516 Grade 60 HIC Tested Boiler Quality Steel Plates , A516 Grade 70 HIC Tested Boiler Quality Steel Plates
