To ensure quality, safety, and performance in critical industrial applications, international standards are essential in the production of clad plates. Developed by recognized bodies such as ASTM, ASME, ISO, and EN, these standards provide detailed specifications for raw materials, manufacturing processes, and mechanical/metallurgical testing.
✅ ASTM B898
Guidelines for the production of explosive welded clad plates, covering bonding quality, thickness requirements, and surface conditions.
✅ ASME SA-263 / SA-264 / SA-265
Standards for clad plates combining carbon or alloy steel with corrosion-resistant metals such as nickel, copper, or stainless steel. These are commonly used in pressure vessels and power plant equipment.
✅ EN 13445-2
Part of the European standard for the design and fabrication of unfired pressure vessels, including material specifications for clad plates.
✅ ISO 15614-12
Guidelines for explosive welding and assessment of dissimilar metal joints, covering bonding quality, structural stability, and testing methods.
✅ Shear Test
Evaluates the strength of the bond between the two metals and ensures proper metallurgical adhesion.
✅ Bend Test
Assesses flexibility and bond quality under bending stress.
✅ Charpy Impact Test
Measures the impact resistance of clad plates, especially in low temperatures.
✅ Ultrasonic Testing (UT)
Used to detect internal defects such as delamination or cracks in the bonding layer.
✅ Metallographic Examination
Microscopic analysis of the bonding interface to identify inclusions, microcracks, or irregularities.
Accurate specification of base and cladding layer thickness
Strict alignment control during bonding
Chemical and physical compatibility of selected metals
Full documentation of manufacturing steps for traceability
Complying with international standards in the manufacturing and testing of clad plates ensures product reliability and builds industrial customer trust. These standards, with their focus on safety, performance, and durability, play a key role in expanding the use of clad plates in high-demand sectors. Companies capable of meeting these requirements gain a strong competitive advantage in global markets.
