Yoane Steel stands out as a top manufacturer and supplier in Kinshasa, Congo, focusing on high-quality SA 516 GR.65N NACE HIC Plates. These plates are crafted for exceptional performance in tough environments where resisting hydrogen-induced cracking and corrosion is crucial. With a strong dedication to precision engineering and adherence to international standards, Yoane Steel delivers durable and reliable steel plates that cater to a variety of industrial needs. The company prides itself on consistent quality, timely deliveries, and tailored solutions to meet the specific demands of clients in the oil, gas, petrochemical, and power generation sectors, both regionally and globally.
SA 516 GR.65N NACE HIC Plates are high-strength pressure vessel plates specially designed for hydrogen-induced cracking (HIC) and sulfide stress corrosion environments. They meet NACE MR 0103/0175 standards, providing superior durability and resistance to harsh environments. These possess Carbon (≤0.26%), Manganese (0.85-1.20%), Silicon (0.15-0.40%), Phosphorus (≤0.025%), and Sulfur (≤0.015%) which impart excellent mechanical strength and durability. Used abundantly in petroleum and gas, petrochemical, and electricity sectors, they provide safety where there is presence of hydrogen sulfide.
| 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. |

SA 516 GR.65N NACE HIC Plates are primarily made up of carbon, manganese, silicon, phosphorus, and sulfur, which contribute to their excellent weldability and notch toughness. These plates boast impressive tensile strength ranging from 415 to 585 MPa and a yield strength of about 240 MPa, ensuring they perform reliably under high pressure and temperature. Thanks to normalized heat treatment, they provide enhanced toughness, outstanding corrosion resistance, and excellent resistance to hydrogen-induced cracking (HIC), making them perfect for challenging industrial conditions.
These plates are commonly used in the fabrication of pressure vessels, boilers, and storage tanks that deal with sour gas and corrosive fluids. Their remarkable resistance to hydrogen-induced cracking makes them vital in refineries, oil and gas processing plants, petrochemical facilities, and offshore platforms. Additionally, they are well-suited for power generation units, heat exchangers, and heavy-duty industrial equipment that require high strength and durability. Their dependable performance in high-pressure and corrosive environments guarantees a long service life and maintains structural integrity in critical applications.
