Nickel alloy bars such as UNS N06600 (Inconel 600) and UNS N06625 (Inconel 625) are widely produced in specialized factories for demanding industrial applications. These alloys are known for their superior corrosion resistance, mechanical strength, and high-temperature performance. By purchasing directly from a factory, customers benefit from competitive prices, customized dimensions, and reliable mill certification according to standards such as ASTM B166 (for N06600) and ASTM B446 (for N06625).

Related Questions and Answers
What is the main difference between N06600 and N06625 nickel alloy bars?
The difference lies in alloying. N06600 (Inconel 600) contains mainly nickel, chromium, and iron, providing oxidation resistance, while N06625 (Inconel 625) has added molybdenum and niobium for superior strength and seawater corrosion resistance.
Which industries prefer N06625 bars over N06600?
Marine, offshore oil & gas, and aerospace industries often prefer N06625 due to its higher strength and resistance to seawater and chloride stress cracking.
Are factory prices more competitive than distributor prices?
Yes. Ordering directly from a nickel alloy bar factory reduces costs by eliminating distributor margins and ensures reliable traceability with mill test certifications.
