Phanuphong Steel is a well-respected manufacturer and supplier located in Bangkok, Thailand, that specializes in high-quality steel plates, including SA 516 GR.70N NACE and MR 0103-0175 Plates. The company is known for its dedication to meeting international standards, providing plates that fulfill rigorous industrial needs. The SA 516 GR.70N plates are specifically crafted for high-pressure applications at moderate and low temperatures, ensuring both reliability and safety. With certifications like NACE and MR 0103-0175 compliance, these plates are perfect for industries that require resistance to hydrogen-induced cracking and sulfide stress corrosion, making them a trusted option around the globe.
The SA 516 GR.70N NACE and MR 0103-0175 Plates are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon, which together provide a balanced mix of strength and toughness. Thanks to their controlled carbon content, these plates boast excellent weldability and notch toughness. In terms of mechanical properties, they offer a tensile strength range of 485–620 MPa and a yield strength of about 260 MPa, ensuring high durability. They undergo normalization to improve their resistance to brittle fracture, and their adherence to NACE and MR 0103-0175 standards guarantees outstanding resistance to hydrogen-induced cracking and sulfide stress corrosion cracking, making them ideal for pressure vessel and boiler 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. |
