Chetak Steel has earned a solid reputation as a reliable manufacturer and supplier of SA 516 GR.70N NACE and MR 0103-0175 Plates in Hyderabad. They cater to critical industrial sectors that require top-notch quality and dependability. With a strong commitment to international standards, Chetak Steel provides plates that boast impressive toughness, strength, and resistance to sour service environments. Thanks to their state-of-the-art processing facilities and rigorous quality control measures, they guarantee consistent performance, precise dimensions, and timely deliveries. Their SA 516 GR.70N NACE plates are highly regarded for their durability and safety in high-pressure and low-temperature applications.
These plates are primarily made up of carbon, manganese, silicon, along with carefully controlled levels of sulfur and phosphorus to meet NACE specifications. They showcase excellent notch toughness, good weldability, and high tensile strength. The normalized condition enhances the grain structure, which in turn improves impact resistance and ensures uniform mechanical properties. Key characteristics include high yield strength, stable elongation, and resistance to hydrogen-induced cracking, making them perfect for sour gas environments. Adhering to MR 0103-0175 guarantees reliability even under pressure and in corrosive conditions.
| 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. |
