Naing Steel stands as a trusted manufacturer and supplier in Naypyidaw, Myanmar, dedicated to meeting the demanding needs of the energy and petrochemical sectors. We specialize in providing high-integrity materials like SA 516 GR.65N NACE HIC plates, which are engineered to withstand some of the most challenging environments. Our commitment lies in delivering robust, reliable steel plates that ensure the safety and longevity of critical infrastructure, supporting the nation’s growing industrial projects with locally produced, world-class quality.
The composition of SA 516 GR.65N NACE HIC plates is carefully controlled to resist hydrogen-induced cracking. This involves strict limits on elements like sulfur and phosphorus, along with specialized processing to create a clean, homogeneous microstructure. Mechanically, these plates offer excellent strength and notch toughness, even in low-temperature service. This unique combination of chemical and physical properties makes them exceptionally durable against the corrosive effects of wet hydrogen sulfide environments found in oil and gas equipment.
| Grade | ASME SA 516 GR.65N 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. |
| Process of Manufacturing | Hot-Rolled (HR) |
| C | Si | Mn | P | S | Al | Cr | Cu | Ni | Mo | Nb | Ti | V |
| 0.08/0.20 | 0.4 | 0.9/1.5 | 0.03 | 0.03 | 0.02 | 0.3 | 0.3 | 0.3 | 0.08 | 0.01 | 0.03 | 0.02 |
| Tensile strength (ksi) | Tensile strength (MPa) | Yield strength (ksi) | Yield strength (MPa) | Elongation in 200mm (min)(%) | Elongation in 50mm (min) (%) |
| 65-85 | 450-585 | 35 | 240 | 19 | 23 |
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
