Premium SA 516 GR.70N NACE and MR 0103-0175 Plates, designed for high-performance use in corrosive and high-pressure environments, are manufactured and supplied by Luke Steel, a reputable company with headquarters in the USA. These plates are well known for their strength, resilience to hydrogen-induced cracking, and durability, which makes them perfect for crucial applications in the petrochemical, energy, and oil and gas industries. Luke Steel makes sure that every product is tested, certified, and optimized to meet the exacting operational demands of industries across the United States and its neighboring regions. The company places a strong emphasis on meeting international standards, delivering products on time, and providing quality customer service.
SA 516 GR.70N Normalized carbon steel plates made especially for sour service applications are known as NACE MR 0103-0175 plates. Carbon (0.27–0.31%), manganese (0.79–1.30%), phosphorus (max 0.035%), and sulfur (max 0.035%) make up their usual composition. In order to meet NACE MR0175 and MR0103 standards, these plates have a minimum yield strength of 260 MPa, a tensile strength of 485–620 MPa, and a low hardness. Their dependability in corrosive, high-pressure settings is guaranteed by their exceptional notch toughness, weldability, and resistance to hydrogen-induced cracking. Their mechanical integrity is improved by normalization, which qualifies them for intricate fabrication and long-term operation under demanding service circumstances.
| 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. |
