Shalan Steel, a top-notch manufacturer and supplier based in Kuala Lumpur, Malaysia, specializes in high-quality NACE MR 0103/0175 HIC Boiler Sheets and Plates. These products are expertly designed to resist hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC) in challenging sour service environments. Adhering to the rigorous standards of NACE MR 0103 and NACE MR 0175/ISO 15156, these plates are tailored for high-pressure, high-temperature, and corrosive applications. Shalan Steel prides itself on precise manufacturing, outstanding surface finishes, and reliable mechanical properties, making these plates a go-to choice for industries like oil & gas, petrochemical, and chemical processing.
The NACE MR 0103/0175 HIC Boiler Sheets and Plates are crafted from premium low-alloy carbon steel, with carefully controlled levels of carbon, manganese, silicon, phosphorus, and sulfur. This optimized blend, along with specialized manufacturing techniques, boosts their resistance to HIC and SSC while ensuring excellent tensile and yield strength. Plus, these plates are designed for good weldability, formability, and impact resistance, making them ideal for creating complex boiler and pressure vessel components.
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.
Process of Manufacturing : Hot-Rolled (HR)
