In Naypyidaw, Myanmar, Naing Steel is a reputable manufacturer and supplier of SA 516 GR.70N NACE and MR 0103-0175 Plates. They offer premium carbon steel plates made to perform exceptionally well in corrosive and high-pressure settings. These plates offer exceptional resistance to sulfide stress corrosion and hydrogen-induced cracking because they have been normalized and certified to meet NACE MR0103 and MR0175 standards. Plates from Naing Steel are renowned for their strength, durability, and weldability, which make them perfect for use in petrochemical facilities, pressure vessel applications, and oil refineries.Â
MR 0103-0175 and SA 516 GR.70N NACE Carbon, manganese, phosphorus, sulfur, and silicon make up the majority of plates, which provide a great mix of strength and durability. The plates have excellent notch toughness even at low temperatures, with a minimum tensile strength of 485–620 MPa and a yield strength of 260 MPa. Their grain structure and mechanical homogeneity are improved by normalizing treatment. These plates are made to withstand stress corrosion and hydrogen-induced cracking. They have exceptional weldability, high ductility, and good impact resistance for pressure vessel-grade performance.
| 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. |
