Naing Steel, a trusted manufacturer and supplier based in Naypyidaw, is proud to produce SA 516 GR.70N NACE HIC plates, a product built for the most demanding environments. We understand that reliability is non-negotiable when equipment faces corrosive challenges, which is why our focus is on delivering plates that offer exceptional resistance to hydrogen-induced cracking. This commitment ensures the longevity and safety of your critical projects, providing a solid foundation of quality and confidence right from the heart of Myanmar.
The composition of these plates is carefully controlled, with lower levels of sulfur and phosphorus to enhance purity and toughness. Mechanically, they offer a minimum yield strength of 38 KSI and tensile strength of 70-90 KSI, providing the robust strength needed for high-pressure service. Crucially, they undergo specialized heat treatment and testing to guarantee superior resistance to hydrogen-induced cracking (HIC), ensuring they perform reliably even when exposed to wet hydrogen sulfide 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. |
