Yousef Steel stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, specializing in high-quality SA 516 GR.70N NACE and MR 0103/0175 Plates. These plates are specifically crafted for pressure vessels and boilers that operate under sour service conditions. Delivered in a normalized (N) state, they meet the stringent NACE MR0103/0175 standards, ensuring exceptional resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSC). With their impressive toughness, weldability, and strength, these plates are in high demand across the oil, gas, petrochemical, and refinery sectors, where reliability and safety are paramount.
The composition of SA 516 GR.70N NACE and MR 0103/0175 Plates includes carbon, manganese, phosphorus, sulfur, and silicon, all meticulously controlled to ensure they perform well in sour gas environments. They boast excellent mechanical properties, featuring tensile strength ranging from 485 to 620 MPa, high yield strength, and remarkable notch toughness. The normalized heat treatment enhances their grain structure and toughness, while compliance with NACE standards guarantees reliable performance in environments containing hydrogen sulfide (H₂S).
| 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. |
