Ahmed Sheets and Plates is a reputed manufacturer and supplier of NACE MR0103/0175 HIC Boiler Sheet and Plates to clients located in Safat, Kuwait. The products it offers are fabricated using superior-grade materials to ensure highly resistant performance in extremely corrosive and hydrogen-induced cracking environments. These plates conform to strict international standards and, hence, could be used in petrochemical plants, refineries, and in the industries that involve processing sour-gas. Ahmed Sheets and Plates has also emphasized durability, accurate fabrication, and consistency in quality for every product to meet arduous service conditions. Advanced facilities and expertise have enabled this company to supply boiler sheets and plates that are reliable for assured long-term performance and safety.
NACE MR0103/0175 HIC Boiler Sheet and Plates are typically made from carbon steel grades that provide improved resistance against hydrogen-induced cracking. The chemical composition has controlled levels of carbon, manganese, sulfur, and phosphorus to ensure enhanced cleanliness and less entrapment of inclusions. These plates exhibit great mechanical properties, including high tensile strength, excellent impact resistance, and enhanced hardness, thus being reliable for service in sour conditions. They are also tested for SSC and HIC resistance in accordance with NACE standards to ensure stable performance under high pressure, increased temperatures, and corrosive operating conditions associated with refining and petrochemical applications.
Grade : ASME SA 516 GR.70N Boiler and Pressure Vessel Steel Plates
Width : 1000mm-4500mm
Thickness : 5mm-150mm
Length : 3000mm-18000mm
Supply Condition : As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
Impact tested : 52° C
Tempering : Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.
Applications : Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.
