Inconel 625 Wire Rod ASTM B446

Product Overview

Inconel 625 wire rod is a nickel-chromium-molybdenum-columbium (niobium) solid-solution strengthened superalloy. It delivers exceptional corrosion resistance, oxidation resistance, and high-temperature strength without the need for age-hardening treatments. The alloy derives its high strength from the stiffening effect of molybdenum and niobium on the nickel-chromium matrix, making it suitable for demanding environments ranging from cryogenic temperatures up to 1800°F (980°C)

Key Features

• Excellent corrosion resistance in a wide range of aggressive media, including mineral acids and alkalis

• Outstanding resistance to pitting and crevice corrosion in chloride-bearing environments

• Immune to chloride-ion stress corrosion cracking, ideal for seawater applications

• High tensile, creep, and rupture strength at elevated temperatures

• No precipitation hardening required — strength is achieved through solid solution strengthening

• Excellent weldability and brazeability
