At Amardeep Steel, we proudly serve as a dedicated supplier and proficient exporter specializing in ASTM A387 / ASME SA387 GRADE 9 Class 2 alloy steel plates. Committed to delivering excellence, we provide top-tier products that meet industry standards, catering to a wide range of industrial applications.

Our alloy steel SA 387 GR. 9 CL. 1/2 plates are expertly crafted for deployment in steel pressure vessels operating at high temperatures and challenging environments. The core composition of this alloy steel incorporates molybdenum, imparting remarkable tensile strength and impressive resistance to corrosion. These plates adhere strictly to the guidelines of ASME SA387, an industry-standard specification governing the production of welded molybdenum steel plates. Their prominence is especially notable in applications requiring performance in elevated temperature conditions.

The infusion of molybdenum and chromium into these alloy steel plates brings a dual enhancement: enhanced tensile strength and fortified resistance against corrosive elements. This combination makes these plates essential for prominent fabricators and diverse industrial sectors. ASME SA387 plates find applications in industrial boilers, pressurized vessels, and heat exchangers.

Understanding the attributes of alloy steel plates involves recognizing their unique qualities. These plates are distinguished by their durability, achieved through meticulous annealing and normalizing processes. These procedures enhance the plates' surface integrity. Annealing relieves internal stresses, resulting in heightened resilience, longevity, and stability of ASME SA387 plates.

Exceptional weldability is another significant attribute of these alloy steel plates, stemming from their flexible manufacturing process. This process imparts remarkable formability to the alloy steel, allowing intricate cutting and seamless shaping into various forms. Alloy steel SA 387 GR. 9 CL. 1/2 plates exhibit a distinct contour and uniform structure, ensuring superior performance in industrial contexts.

Undoubtedly, these plates excel due to their exceptional performance, largely due to their multifaceted anti-corrosion properties. Their robustness enables them to endure extreme temperatures and harsh environments, making them ideal for critical applications. Celebrated for their exceptional tensile strength, extended lifespan, and inherent corrosion resistance, these plates stand out.

Familiarity with the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum is crucial for making informed purchases of high-quality products. Plate specifications include thicknesses ranging from 6mm to 300mm, widths from 1500mm to 4050mm, and lengths from 3000mm to 15000mm. The manufacturing process involves hot rolling. Dimensions of these alloy steel plates vary from 1.5mm to 260mm in thickness, 1000mm to 4000mm in width, and 1000mm to 18000mm in length. Rigorous testing and inspection, overseen by quality experts and certified agencies, ensure certificates for high-temperature tension tests, Charpy V-Notch impact tests, flattening tests, and comprehensive third-party inspection reports.

Upon completion, Alloy steel SA 387 GR. 9 CL. 1/2 plates undergo meticulous preparation for delivery. Each plate is individually wrapped in waterproof plastic and then enclosed in wooden cases or boxes. These packages are carefully labeled with essential product details such as size, length, thickness, and specifications, ensuring protection against rust and transit damage.
