Product Overview

Inconel Series Nickel Base Super Alloy Plate is a premium nickel-chromium based high-performance alloy material, covering Inconel 600, Inconel 601, Inconel 625, Inconel 718, Inconel X-750, Inconel 800 / 800H / 800HT grades. The alloy is formulated with nickel, chromium, molybdenum, niobium and other alloying elements, designed to maintain stable physical and mechanical properties under continuous ultra-high temperature, high pressure and harsh corrosive working conditions.

Inconel 600 & 601 are classic high-temperature oxidation-resistant grades; Inconel 625 provides excellent corrosion and fatigue resistance; Inconel 718 features precipitation hardening and high tensile strength; Inconel X-750 owns high strength after aging treatment; Inconel 800/800H/800HT keeps stable long-term creep performance under elevated temperature.

We supply both cold rolled thin sheet and hot rolled thick plate. Cold rolled plate ranges from 0.1–3.0 mm, hot rolled plate from 3–200 mm, customized thickness maximum up to 250 mm. Standard dimensions include 1000×2000mm,1220×2440mm,1500×3000mm, extra-long plate can reach 12000mm. Water jet cutting, fixed-length cutting and irregular blanking services are supported.

Widely used in aerospace, gas turbine, nuclear power equipment, high-temperature furnace components, petrochemical reactors and thermal processing industry. All products come with mill test certificates, third-party NDT reports and full material traceability documents to meet strict industrial procurement and inspection requirements.
