Nestled in the industrial heart of Muscat, Faisal Steel has carved a distinguished reputation as a trusted manufacturer and supplier, specializing in the precise demands of boiler quality sheet and plate. We understand that such materials are the bedrock of safety and performance in high-pressure environments, which is why our commitment extends beyond mere supply to ensuring every piece meets the most stringent international standards. Our focus is on providing reliability you can build upon, serving the critical needs of Oman’s energy and industrial sectors with integrity and expert technical support.
The integrity of boiler quality plate hinges on its specific composition and mechanical properties. These steels are carefully crafted, typically featuring carbon-manganese grades often enhanced with micro-alloying elements to achieve superior strength and resilience. Crucially, they possess excellent tensile strength and yield points to withstand immense pressure, while their enhanced toughness, even at low temperatures, prevents brittle fracture. This combination ensures they can endure the cyclic stresses and high temperatures found inside boilers and pressure vessels, forming a reliable barrier under demanding operational conditions.
Standard:Â ASTM A516 / ASME SA 516 Gr 60 / 65/ 70
Width:Â 1000mm-4500mm
Thickness:Â 5mm-150mm
Length:Â 3000mm-18000mm
Supply Condition :Â As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
Impact tested : -52° C
Tempering:Â 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 :Â Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.
Process of Manufacturing :Â Hot-Rolled (HR)
