MMS 2601 - Boeing Specification for INCONEL 718 Tubing
MMS 2601 is a Boeing company document that outlines the specifications with regard to INCONEL 718 tubing; INCONEL 718 tubing is a nickel-based alloy with excellent resistance against corrosion, working well under extreme temperatures as well. This standard is specifically related to nickel-based tubes used in Boeing’s Defense, Space & Security (BDS) division.
Material Overview
MMS 2601 retains excellent mechanical properties at temperatures up to 1300°F (704°C) and resists corrosion in both oxidizing and reducing environments. Key characteristics include:
Exceptional corrosion and oxidation resistance
High strength-to-weight ratio
Excellent fatigue and creep resistance
Good weldability and formability for aerospace tubing
Boeing Quality and Compliance
MMS specifications originate from Boeing’s St. Louis facility under D1-4426 Approved Process Lists. MMS2601 / MMS 2601 originated at the St. Louis facility, therefore it is widely used for Boeing’s aircraft manufacturing in relation to Defense, Space, and Security products.
