Latham Steel, a reputable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality NACE MR0103/0175 HIC Boiler Sheets and Plates designed for tough sour-service environments. These plates are engineered to resist hydrogen-induced cracking (HIC) and sulfide-stress corrosion, making them vital for oil, gas, and petrochemical industries where corrosive substances are a concern. Latham Steel guarantees full adherence to NACE standards, providing plates that boast impressive toughness, durability, and pressure resistance. Their NACE-certified HIC plates are commonly utilized in refineries, pressure vessels, heat exchangers, and essential pipeline systems that require long-lasting safety, stable performance, and maximum crack resistance in acidic conditions.
NACE MR0103/0175 HIC Boiler Plates are crafted from high-purity carbon steel, with carefully regulated levels of carbon, sulfur, and phosphorus to minimize the risk of impurity-related cracking. The addition of alloying elements like manganese and silicon boosts strength and stability. These plates undergo specialized heat treatment and rigorous hydrogen-induced cracking tests to meet NACE HIC and SSC standards. They deliver strong yield and tensile strength, outstanding impact toughness, and excellent resistance to blistering and stepwise cracking. The refined microstructure ensures good weldability and dependable performance in sour-gas environments.
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)
