Naing Steel proudly stands as a leading manufacturer and supplier in Naypyidaw, Myanmar, specializing in high-performance steel plates essential for demanding industrial environments. Our focus is on providing superior SA 516 GR.6070N NACE HIC Plates, engineered specifically to withstand the challenges of sour service applications. We understand that the integrity of your equipment is paramount, which is why we are committed to delivering materials that offer exceptional resistance to hydrogen-induced cracking, ensuring both safety and long-term operational reliability for your critical projects.
The composition of these plates is carefully controlled, with lower levels of sulfur and phosphorus, to ensure a clean, homogeneous microstructure. This specific chemistry is key to their impressive mechanical properties, which include high tensile strength and excellent notch toughness, even in low-temperature conditions. The result is a plate that doesn’t just meet the standard but consistently exceeds expectations for durability and performance under pressure, providing a reliable foundation for building robust and safe industrial assets.
| Grade | ASME SA 516 GR.60/70N 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. |
