Latham Steel, a prominent manufacturer and supplier located in Hamilton, New Zealand, specializes in high-performance SA 516 GR.70N NACE HIC plates that are specifically designed for harsh, corrosive, and high-pressure environments. These plates are normalized to enhance toughness and rigorously tested to comply with the strict NACE MR0175/ISO 15156 standards, ensuring they resist hydrogen-induced cracking. Tailored for sour service applications, they offer exceptional strength, reliability, and long-lasting durability. Latham Steel provides these plates with precise dimensions, robust structural integrity, and consistent quality, making them perfect for demanding sectors like oil & gas, petrochemical processing, and high-pressure vessel fabrication.
SA 516 GR.70N NACE HIC plates are crafted with carefully controlled levels of carbon, manganese, silicon, sulfur, and phosphorus, along with micro-alloying elements that boost toughness and crack resistance. This material boasts a minimum yield strength of around 260 MPa and a tensile strength ranging from 485 to 620 MPa. The normalizing process enhances the grain structure, resulting in superior ductility and impact resistance. These plates undergo hydrogen-induced cracking (HIC) testing to guarantee their performance in sour environments. Their excellent weldability, uniform hardness, and strong resistance to brittle fracture make this grade ideal for high-pressure and corrosive-service 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. |
