Shalan Steel, a prominent manufacturer and supplier located in Kuala Lumpur, Malaysia, specializes in high-quality SA 516 GR.70N NACE and MR 0103-0175 Plates designed specifically for pressure vessels and boiler applications in challenging corrosive environments. These plates undergo a normalization process to boost their toughness and comply with the stringent NACE MR0175 and MR0103 standards, ensuring they resist sulfide stress cracking in sour gas conditions. With a focus on precision and consistent quality control, these plates deliver outstanding weldability, durability, and performance, making them perfect for the oil, gas, petrochemical, and power generation industries where safety and reliability are paramount.
The SA 516 GR.70N NACE and MR 0103-0175 Plates are crafted with a carefully balanced mix of carbon, manganese, silicon, phosphorus, and sulfur, along with fine microalloying elements that enhance strength and toughness. The normalization process refines the grain structure, improving impact resistance and ductility. These plates boast a minimum tensile strength of 485–620 MPa and exceptional resistance to hydrogen-induced cracking, ensuring they have a long service life even in harsh operating conditions. Meeting NACE specifications confirms their suitability for sour 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. |
