Product Introduction
Inconel Alloy Plate is a high-performance nickel-chromium superalloy engineered for demanding industrial environments characterized by extreme thermal exposure, intense pressure, and highly corrosive media. This premium alloy maintains superior tensile strength, excellent creep-rupture properties, and structural integrity during long-term exposure to elevated temperatures.
As a reliable solution for critical applications, Inconel sheet and plate products provide exceptional resistance to high-temperature oxidation, scaling, pitting, and chloride-stress corrosion cracking, outperforming conventional stainless steel in aggressive processing environments.
Available Grades
Inconel 600 Plate (UNS N06600): Optimized for heat-treatment fixtures, furnace components, and chemical processing equipment requiring oxidation resistance up to 1093°C.
Inconel 601 Plate (UNS N06601): Formulated with aluminum to deliver exceptional resistance to high-temperature oxidation, green rot, and nitriding.
Inconel 625 Plate (UNS N06625): Alloyed with molybdenum and niobium for superior high-strength performance and excellent resistance to pitting and crevice corrosion in marine and acid environments.
Inconel 718 Plate (UNS N07718): Age-hardenable superalloy combining high yield strength with excellent weldability for high-stress structural components up to 704°C.
