Manufacturing and Processing Variants
The sheets and plates of Inconel are also provided in various manufacturing conditions depending on the thickness, grade, and application requirements. Hot-rolled plates are mostly applied to heavier sections and structural parts, whereas cold-rolled sheets are favored at thinner gauges, tighter tolerances, and a better surface finish. Precision processing can be offered in strips, coils, and shims.
Standard Thickness Range
The thickness of Inconel flat products is in a large range. Sheets are usually supplied between 0.3 mm and 6 mm, whereas plates are generally supplied between 6mm and 100 mm, but this depends on the grade and standard. Shims and strips are made out of thinner gauges, and pressure vessels and heavy-duty are made out of heavier plates.

An Inconel plate is a flat rolled product that is manufactured with nickel-chromium superalloys that are used to sustain the environmental conditions of extreme heat, pressure, and corrosion. The whole chemical processing, oil and gas, aerospace, power generation, and marine use of inconel plates are in areas where stainless steel cannot be reliably used.
The price of Inconel 625 plate is determined by the thickness, size, surface finish, quantity, and the prevailing rates of the nickel market. Prices are either market reflective or different according to grade and specification. To get the right price, one is advised to provide the size required, standard, and applicability.
Inconel is costly because it has high nickel content, complicated alloying components like molybdenum and niobium and its special manufacturing processes. Melting, heat treatment and complex processing are necessary to make these alloys, making them expensive to manufacture, but allowing them to work in harsh conditions.
Inconel 600 is superior to SS 304 in the high-temperature and corrosion characteristics. Although SS 304 is generally good in general environments, Inconel 600 has better oxidation resistance, high temperature strength, and chloride stress corrosion cracking resistance and thus it is suitable in challenging industrial environments.
Some applications of the Inconel plates and sheets include heat exchangers, pressure vessels, reactors, exhaust systems, furnace components, offshore structures, and aerospace components. They are suitable for critical service applications due to their capacity to maintain strength and resist corrosion at high temperatures.
The Inconel plates and sheets are generally used in Inconel 600, 601, 625, 718, X 750, 617, and 825. The grades used depend on temperature limits, corrosion resistance and the need of mechanical strength.
Yes, Inconel plates and sheets may be welded and made using the appropriate processes. Techniques of welding, like GTAW and GMAW, are mostly employed as well as corresponding filler materials. The integrity of the material is ensured by the proper heat input control and after-weld treatment.
