Situated in the industrial heart of Manama, Ahmer Steel has established itself as a trusted partner for high-pressure and high-temperature projects. We take pride in our role as a leading supplier of specialized materials, including the robust ASME SA 387 Grade 11 Class 1 & 2 sheets and plates. This particular grade is engineered for demanding service, making it an essential component for industries where reliability under extreme conditions is not just a preference but an absolute necessity. Our commitment is to provide material integrity that matches the ambition of your most critical applications.
The strength of this material comes from its precise composition, primarily chromium and molybdenum, which gives it excellent resistance to corrosion and high temperatures. In terms of mechanical properties, it offers impressive tensile and yield strength, ensuring it can withstand significant internal pressure and structural loads. Whether you’re working with Class 1 for normalized heat treatment or Class 2 for the added toughness of normalized and tempered processing, this grade provides a dependable foundation for building equipment that must perform reliably under sustained stress and heat.
