Amardeep Steel stands as a dedicated supplier and proficient exporter, specializing in ASTM A387 / ASME SA387 GRADE 5 Class 1 alloy steel plates. With a steadfast commitment to excellence, Amardeep Steel delivers top-quality products that align with industry standards, catering to diverse industrial applications.

Alloy steel SA 387 GR. 5 CL. 1/ 2 represents a specialized type of chrome molybdenum steel plate meticulously designed for deployment within steel pressure vessels that endure high temperatures and challenging environments. The core composition of this alloy steel integrates molybdenum, conferring exceptional tensile strength to the base steel and bestowing it with commendable resistance against corrosion.


These plates adhere to the stringent guidelines of ASME SA387, an industry-standard specification governing the manufacturing of welded molybdenum steel plates. Their prevalence is particularly pronounced in applications demanding performance under elevated temperatures.

Notably, the strategic infusion of molybdenum and chromium into these alloy steel plates engenders a dual enhancement: heightened tensile strength and fortified resistance against corrosive forces. This synergy renders the plates indispensable across prominent fabricators and diverse industrial sectors. The spectrum of applications encompassed by ASME SA387 encompasses industrial boilers, pressurized vessels, and heat exchangers.

A deeper understanding of alloy steel plates must encompass their distinctive attributes. A marked durability characterizes these plates, a quality attained through meticulous annealing and normalizing procedures. These processes are meticulously employed to instill the plates with a robust surface constitution. During annealing, the surface undergoes a transformative hardening process by relieving internal stresses. Consequently, ASME SA387 plates exhibit heightened resilience, longevity, and stability.

Another noteworthy attribute of these alloy steel plates is their exceptional weldability. This characteristic is a result of the ingeniously malleable manufacturing process. Manufacturers leverage this process to imbue the alloy steel with remarkable formability, enabling it to be intricately cut and seamlessly fashioned into diverse shapes. The plates in the category of Alloy steel SA 387 GR. 5 CL. 1/ 2 exhibit a distinct contour and uniform structure, thus yielding superior performance within industrial contexts.

Undoubtedly, these plates stand out for their remarkable performance, a virtue attributed to their multifaceted anti-corrosion attributes. Their robustness allows them to withstand the rigors of extreme temperatures and environments, a quality that endorses their utility in critical applications. These plates are celebrated for their exceptional tensile strength, extended lifespan, and inherent resistance to corrosion.

Familiarity with the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum is of paramount importance, as it guides consumers in making informed purchases of top-quality products. Turning attention to plate specifications, the thickness spans from 6mm to 300mm, width ranges from 1500mm to 4050mm, and length extends from 3000mm to 15000mm. Manufacturing employs the hot rolling process. The dimensions of these alloy steel plates range from 1.5mm to 260mm in thickness, 1000mm to 4000mm in width, and 1000mm to 18000mm in length. Rigorous testing and inspection under the purview of quality experts and certified agencies are conducted. This results in the issuance of 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. 5 CL. 1/ 2 plates are meticulously prepared for delivery. They are individually enveloped in waterproof plastic wrappings and subsequently encased within wooden cases or boxes. These cases or boxes are meticulously labeled with pertinent product details such as size, length, thickness, and specifications. This comprehensive packaging approach is designed to thwart rusting and mitigate any potential damage during transit.
