Yoane Steel, located in Kinshasa, Congo, stands out as a top manufacturer and supplier of SA 516 GR.70N NACE and MR 0103-0175 Plates. These plates are celebrated for their exceptional quality, reliability, and performance, especially in tough industrial settings. The company takes pride in delivering these plates with meticulous engineering and rigorous quality control, ensuring they boast impressive strength, weldability, and resistance to corrosion. Yoane Steel serves a variety of industries, including oil and gas, petrochemical, and power generation, providing tailored solutions that adhere to international standards and excel under extreme pressure and temperature.
SA 516 GR.70N NACE MR 0103-0175 Plates are carbon steel pressure vessel plates of high strength that are suitable for sour service use with good resistance to hydrogen-induced cracking. The plates have Carbon (0.27%), Manganese (0.85-1.20%), Phosphorus (≤0.025%), Sulfur (≤0.015%) and Silicon (0.13-0.45%), which make them highly durable and resistant to corrosion. Meeting NACE MR 0103 and MR 0175 standards, they are suitable for use in pressure vessels, boilers, and storage tanks in severe environments where high performance and reliability are needed.
| 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. |

The SA 516 GR.70N NACE and MR 0103-0175 Plates are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon, which contribute to their remarkable toughness and ability to resist hydrogen-induced cracking. These normalized plates showcase high tensile strength, ranging from 485 to 620 MPa, with a yield strength of about 260 MPa. They are known for their outstanding notch toughness, fine grain structure, and excellent weldability, making them perfect for sour service environments. Their compliance with NACE and MR 0103 standards enhances their corrosion resistance in environments containing hydrogen sulfide, ensuring they remain durable even in challenging conditions.
These plates find extensive application in the construction of pressure vessels, boilers, heat exchangers, and storage tanks that operate in sour gas and oil service environments. They are particularly well-suited for use in refineries, chemical plants, and offshore platforms, where resistance to hydrogen-induced and stress corrosion cracking is essential. Additionally, these plates are utilized in power generation and natural gas processing units, offering durability and safety under high pressure and temperature. Their strong mechanical properties guarantee reliable performance in corrosive and high-stress industrial operations.
