Bosega Pipes and Tubes, located in Cape Town, South Africa, stands out as a top manufacturer and supplier of SA 516 GR.70N NACE and MR 0103-0175 Plates. Known for its unwavering dedication to quality and precision, the company delivers robust and high-performance steel plates that are perfect for tough industrial applications. With a strong emphasis on adhering to international standards and meeting client needs, Bosega guarantees that each plate provides exceptional strength, reliability, and resistance to corrosion. This commitment has made them a trusted name in various sectors, including oil and gas, petrochemical, and power generation, both in South Africa and beyond.
The SA 516 GR.70N NACE and MR 0103-0175 Plates are primarily made up of carbon, manganese, silicon, phosphorus, and sulfur, all crafted to ensure outstanding notch toughness and corrosion resistance in sour service environments. These plates boast a minimum tensile strength ranging from 485 to 620 MPa and a yield strength of about 260 MPa, with improved impact properties thanks to normalization. Their unique chemical makeup and mechanical balance make them ideal for pressure vessels and boilers that face hydrogen sulfide-rich conditions, ensuring they remain durable, weldable, and perform reliably over the long haul, even in harsh environments.
| 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. |
