Filiz Steel guarantees that its NACE MR 0103/0175 HIC boiler plates adhere to international standards, boasting precise dimensional accuracy, consistent mechanical properties, and excellent weldability.
The NACE MR 0103/0175 HIC Boiler Sheets and Plates are made from carbon-manganese steel, with a carefully controlled chemical composition that includes low sulfur and phosphorus levels to boost resistance against hydrogen-induced cracking. They offer impressive tensile and yield strength, outstanding notch toughness, and remarkable impact resistance, even in low temperatures. These plates undergo specific processing and testing to meet NACE MR0103/0175 standards, ensuring reliable performance in sour and corrosive environments while maintaining good weldability and formability for use in boilers, pressure vessels, and piping systems.
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)
