Phanuphong Steel is a reputable steel manufacturer and supplier located in Bangkok, Thailand. They focus on delivering top-notch SA 516 GR.65N NACE and MR 0103-0175 plates. With years of experience under their belt, the company is dedicated to providing durable and reliable steel plates that adhere to international standards, especially for industries that demand exceptional performance in tough conditions. These plates are produced with rigorous quality control to ensure they resist hydrogen-induced cracking and sulfide stress corrosion, making them perfect for use in the oil, gas, and petrochemical sectors, where safety and reliability are crucial.
The SA 516 GR.65N NACE and MR 0103-0175 plates are mainly made up of carbon, manganese, silicon, phosphorus, and sulfur, all in carefully controlled amounts, along with some trace alloying elements to boost strength. They undergo a normalization process to enhance toughness and structural integrity. These plates are known for their excellent weldability, impressive tensile strength (ranging from 450 to 585 MPa), and a yield strength of about 260 MPa. Their outstanding notch toughness guarantees safe operation in both low-temperature and high-pressure settings. Meeting the NACE MR0175 standards, these plates are designed to resist hydrogen-induced cracking (HIC) and sulfide stress corrosion, ensuring dependable performance in challenging environments.
| 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. |
