Thabiso Steel is a trusted manufacturer and supplier based in Cape Town, South Africa, specializing in high-quality pressure vessel plates such as SA 516 GR.60N NACE and MR 0103-0175 Plates. These plates are designed to meet the rigorous demands of the oil, gas, and petrochemical industries, particularly in environments prone to hydrogen-induced cracking. Thabiso Steel ensures each product meets international standards, offering clients reliable performance and durability. With a commitment to quality, technical expertise, and timely delivery, Thabiso Steel serves as a reliable partner for clients seeking corrosion-resistant and code-compliant steel plate solutions across various industrial sectors.
The SA 516 GR.60N NACE and MR 0103-0175 plates are carbon steel pressure vessel plates specifically modified to comply with NACE (National Association of Corrosion Engineers) standards for sour service. Their typical chemical makeup includes carbon (≤0.21%), manganese (0.55–1.30%), phosphorus (≤0.025%), sulfur (≤0.015%), and silicon (0.13–0.45%). These plates are normalized to enhance toughness, boasting impressive mechanical properties: a minimum tensile strength of 415–550 MPa, yield strength of at least 260 MPa, and good notch toughness. They meet the NACE MR0103 and MR0175 standards, ensuring they resist hydrogen sulfide (H₂S) corrosion cracking in harsh sour environments.
| Grade | ASME SA 516 GR.60N 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. |
| Process of Manufacturing | Hot-Rolled (HR) |
| C | Si | Mn | P | S | Al | Cr | Cu | Ni | Mo | Nb | Ti | V |
| 0.20 | 0.4 | 0.95/1.50 | 0.025 | 0.025 | 0.02 | 0.3 | 0.3 | 0.3 | 0.08 | 0.01 | 0.03 | 0.02 |
