ASTM B443 Inconel 625 Mirror Polished Nickel Alloy Decorative Architectural Panel
ASTM B443 Inconel 625 Mirror Polished Nickel Alloy Decorative Architectural Panel
ASTM B443 Inconel 625 mirror-polished nickel alloy decorative architectural panel is a high-performance sheet metal made from a nickel-chromium-molybdenum-niobium alloy. It offers excellent corrosion and high-temperature resistance and a mirror-like finish when polished, making it suitable for aesthetically pleasing architectural and design applications. ASTM B443 specifies the requirements for Inconel 625 (UNS N06625) in plate and sheet forms.
What are the properties of 625 nickel alloy?
625 alloy is a nonmagnetic, corrosion- and oxidation-resistant nickel-based alloy. Its excellent performance in the temperature range from cryogenic to 2000°F (1093°C) is primarily due to the solid solution effect of the refractory metals niobium and molybdenum in the nickel-chromium matrix.
Inconel 625 plate is widely used in industries such as aerospace, chemical processing, pollution control, and oil and gas. Components such as engine exhaust manifolds, turbine blades, heat exchangers, and rocket motor casings rely on its strength at high temperatures. The petrochemical industry uses Inconel 625 plate to resist pitting corrosion and stress corrosion cracking.
ASME SB443 Inconel 625 plate offers durability and strength under severe operating conditions. Parts maintain integrity through repeated heating and cooling cycles. The plate has an expected lifespan twice that of austenitic stainless steel.
