At Amardeep Steel, we proudly serve as a dedicated supplier and proficient exporter specializing in
ASTM A387 / ASME SA387 GRADE 5 Class 1 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. 5 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. 5 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. 5 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.
