Latham Steel, a reputable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality SA 516 GR.70N NACE and MR 0103/0175 Plates, specifically designed for sour-service and high-pressure applications. These normalized pressure vessel plates are crafted to provide outstanding toughness, corrosion resistance, and structural stability in environments where hydrogen sulfide (H₂S) is present. Latham Steel guarantees that all plates comply with strict ASME, NACE MR0103, and NACE MR0175 standards, making them ideal for refineries, oil & gas processing, and chemical industries. With a strong focus on quality control and a reliable supply chain, Latham Steel offers dependable steel solutions for critical, safety-sensitive industrial operations.
SA 516 GR.70N NACE and MR 0103/0175 Plates are made from fine-grained carbon steel, which contains carefully controlled levels of carbon, manganese, silicon, and trace alloying elements to boost strength and crack resistance. The normalizing treatment enhances toughness and helps prevent brittle fractures. These plates boast high tensile and yield strength, excellent notch toughness, and robust resistance to hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC). Their mechanical performance remains consistent under high pressure and fluctuating temperatures, making them perfect for sour-service environments that demand reliable structural integrity.
| 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. |
