Technical Overview of Inconel 625 Plate and Inconel 600 Plate for Industrial Applications

Nickel-chromium alloys are extensively applied in high-temperature and corrosive industrial environments, particularly in oil, gas, and power generation sectors. Inconel 625 Plate, designated as UNS N06625 and commonly produced in accordance with ASTM B443 and ASME SB443, is strengthened through solid solution hardening by the addition of molybdenum and niobium. The alloy demonstrates tensile strength typically above 760 MPa in the annealed condition and maintains excellent fatigue resistance. Plate thicknesses generally range from 3 mm to 50 mm or more, supplied in hot-rolled or solution-annealed conditions. Its resistance to pitting, crevice corrosion, and chloride stress corrosion cracking makes it technically suitable for heat exchangers, subsea components, and pressure vessels operating at temperatures approaching 980°C.

Material engineers often compare chemical composition, creep rupture data, and weldability before finalizing alloy selection. Microstructural stability and oxidation resistance remain key evaluation parameters in refineries and processing facilities located in Riyadh and Dammam. Access to verified technical documentation, including mill test certificates and third-party inspection reports, supports compliance with project specifications and international codes.

In applications requiring reliable performance in carburizing or nitriding atmospheres, Inconel 600 Plate (UNS N06600) manufactured under ASTM B168 offers a balanced nickel-chromium-iron composition with strong resistance to stress corrosion cracking. It is commonly supplied in multiple tempers and thickness classes for furnace fixtures, chemical processing equipment, and thermal units across industrial sectors in Jeddah and other regions of Saudi Arabia.
