ASTM B564 N06625 Round Rod, Inconel 625 Nickel-Based Alloy Solid Round Bar for High Corrosion Service
Brief Introduction
ASTM B564 N06625 Round Rod is a high-performance nickel-based superalloy solid round bar, strictly manufactured in accordance with ASTM B564 and ASME SB564 standards. N06625 (commonly known as Inconel 625) is a premium nickel-chromium-molybdenum-niobium alloy, featuring excellent high-temperature strength, outstanding corrosion resistance (resistant to most acids, alkalis, chloride media, and seawater), and good weldability and formability. It is specially designed for harsh working environments such as high temperature, high pressure, and strong corrosion, widely applied in aerospace, petrochemical, marine engineering, and other critical industrial fields.
