Situated in Manama’s dynamic industrial landscape, Ahmer Steel has solidified its standing as a trusted manufacturer and supplier for demanding projects across the Gulf and beyond. We take particular pride in our expertise with high-pressure, high-temperature materials, specializing in the reliable provision of ASME SA 387 Grade 22 Class 1 & 2 sheets and plates. Our commitment is to deliver not just metal, but engineered solutions backed by stringent quality assurance, ensuring every piece meets the rigorous standards required for critical applications in harsh operating environments.
The composition of ASME SA 387 Grade 22 Class 2 is centered on chromium-molybdenum alloy steel, specifically formulated with around 2.25% chromium and 1% molybdenum. This specific chemistry grants the material exceptional strength and resistance to oxidation and corrosion, particularly under elevated temperatures. The mechanical properties are precisely defined by the ASME standard, ensuring superior tensile strength and yield strength. The key distinction between Class 1 and Class 2 lies in the advanced heat treatment process for Class 2, which provides enhanced tensile properties for even more demanding service conditions.

These robust plates are essential for constructing critical components that operate under intense pressure and heat. You will typically find them fabricated into heavy-duty pressure vessels, industrial boilers, and reactors within the petrochemical, power generation, and oil and gas sectors. Their exceptional resistance to hydrogen attack and high-temperature creep makes them ideally suited for critical service, such as in refinery hydrocrackers or fossil-fuel power plants. Essentially, they are the material of choice for any application where long-term reliability under severe thermal and mechanical stress is an absolute necessity.
