Facing extreme heat and corrosive chemical exposure in critical power plant components, engineers shifted to the superior endurance of Inconel Sheets. These sheets provided exceptional corrosion resistance, thermal stability, and mechanical strength, drastically extending component life and improving plant safety. Today, Inconel sheets supplied by Aurico Alloys LLP are fundamental to chemical, marine, oil & gas, pharma, and power generation industries demanding lasting reliability.
Table of Contents:
Inconel is a family of nickel-chromium alloys rather than a single material, and on a sheet order the grade is the decision. Aurico Alloys LLP supplies Inconel sheet in ten of them: the general-purpose corrosion grades 625 and 600, the aluminium-bearing 601, the creep-resistant 617, the low-cycle-fatigue 625 LCF, the high-molybdenum 686, the high-chromium 690, the metal-dusting-resistant 693, the age-hardened 718 and the spring grade X-750. What they share is a nickel-chromium base that holds strength and resists oxidation, pitting and stress corrosion cracking where stainless steels stop being an option – heat exchangers, pressure vessels, reactors and turbo machinery. What they do not share is a specification: each is rolled to the flat-product standard written for it, and those are listed grade by grade below.
Aurico Alloys LLP stocks Inconel sheets with thickness from 0.2 mm to 4.75 mm, widths up to 2500 mm, and customizable lengths, available in bright, polished, annealed, or ground finishes. With full mill test certificates including PMI and environmental compliances, our Inconel sheets meet international standards ensuring trustworthy quality for every project.
Beyond physical toughness, Inconel sheets exhibit excellent fabricability and weldability, critical for the dynamic construction of process equipment. Their stability under repeated thermal cycling and corrosive exposure reduces costly downtime and replacement cycles, offering long-term value and operational confidence.
High-quality Inconel Sheets ready for industrial use.

Mechanical & Physical Properties
Density and melting range for all ten grades are in the Equivalent Grades & Standards tables above, each one read off the mill bulletin named beneath it.
Tensile strength, yield strength and elongation are not averaged into a single table here, because they are properties of a grade in a condition rather than of the family: an age-hardened 718 sheet and an annealed 600 sheet are not comparable numbers, and the same grade differs by thickness and temper. Each grade's own sheet page publishes its figures, and the mill test certificate supplied with your order states the results for the material you actually receive.
Applications & Benefits
- Chemical: acid reactors, catalyst furnaces, heat exchangers, evaporators
- Marine: seawater corrosion-resistant piping, antifouling systems
- Oil & Gas: subsea pipelines, sour gas components, refinery equipment
- Pharma: sterilization chambers, chemical reactors, high-purity process vessels
- Power: turbine components, emission control, superheater tubes
