Inconel 625 Plate

What is Inconel 625 Plate?

Inconel 625 plates are made from a nickel-based alloy known for its strength and corrosion resistance. These plates perform well in high temperatures and harsh environments. Parag Metal is a trusted Inconel 625 plates supplier in India, offering reliable stock and quick delivery. The plates are utilized in nuclear power plants, offshore oil rigs, marine services and aerospace components, with other applications. UNS N06626-625LCF is a common grade that is known for its resilience to high temperatures and pressures.

 

Inconel Alloy 625 Plates have  a high tensile strength and resist pitting and crevice corrosion. It offers good weldability and do not need post-weld heat treatment. The chemical mix includes nickel, chromium, molybdenum and niobium. This blend gives the alloy its strong anti-corrosion and heat-resistant qualities. It works well in both acidic and oxidizing environments. These plates stay stable and strong even in very hot or cold conditions.

Inconel 625 plates are manufactured in accordance with internationally recognized standards such as ASME SB 443 Grade 1 and ASTM B 443 Grade 1, ensuring consistent quality and reliable performance across demanding applications. These plates are available in a wide thickness range starting from 3 mm and going up to 100 mm, making them suitable for both lightweight fabrication and heavy-duty structural use. Standard widths can extend up to 2000 mm, while lengths are fully customizable based on specific project requirements. Strict dimensional accuracy is maintained throughout production, with close control over thickness tolerance, width precision, and surface flatness to ensure smooth fabrication and proper fit during installation.


Quality assurance remains a critical part of the supply process. Each Inconel 625 plate undergoes comprehensive testing to verify its mechanical strength, hardness, and overall durability. This includes ultrasonic testing to detect internal flaws, Positive Material Identification (PMI) to confirm chemical composition, hardness testing to assess surface strength, and tensile strength testing to evaluate load-bearing capacity. These inspections help guarantee that every plate delivered performs reliably under high pressure, elevated temperatures, and corrosive environments.
