Nestled in the heart of Manama’s industrial landscape, Ahmer Steel stands as a trusted partner for those demanding the very highest standards in material performance. We specialize in supplying premium Boiler Quality Sheet and Plate, a product line defined by unwavering reliability. Our commitment is to provide materials that form the sturdy backbone of critical systems, empowering industries to build with confidence and ensure the longevity and safety of their most essential pressure-containing equipment, where failure is never an option.
The integrity of Boiler Quality steel hinges on its precise composition and mechanical properties. These plates are typically crafted from fine-grained steels, often incorporating elements like silicon and manganese for strength. They are engineered to possess excellent tensile strength and, just as importantly, superior notch toughness to resist brittle fracture. This is complemented by exceptional weldability, allowing for the creation of strong, seamless joints that can reliably withstand the intense pressures and high temperatures they will face in service.
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)
