Desta Steel, operating from the heart of Addis Ababa, stands as a trusted partner for Ethiopia’s most demanding industrial projects. We are proud suppliers of specialized pressure vessel plates like SA 516 GR.70N NACE HIC, an alloy engineered for resilience in challenging environments. Understanding the critical nature of your operations, we provide materials that offer superior resistance to hydrogen-induced cracking, ensuring long-term reliability and safety for your equipment. Our commitment is to support the nation’s growth with high-integrity steel.
The composition of SA 516 GR.70N NACE HIC plates is carefully controlled, particularly with lower sulfur and phosphorus levels, to enhance purity and toughness. This specific chemistry provides excellent mechanical properties, including a minimum yield strength of 38 ksi and tensile strength ranging from 70 to 90 ksi. Most importantly, the plates undergo rigorous testing to guarantee their performance against hydrogen-induced cracking (HIC), making them exceptionally durable under corrosive conditions where wet hydrogen sulfide is present.
| 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. |
