Overview of ASTM B626 Specification
ASTM B 626 sets the specifications of welded tubes that are made out of nickel and nickel-cobalt alloys that are used to build corrosion-resistant and high-temperature tubes. The specification provides an illustration of chemical content standards, mechanical characteristics, manufacturing, heat treatment, and tests.
These welded tubes are made by means of automatic welding without filler metal, cold working and solution annealing which presents uniform grain structure, high quality of weld and consistent mechanical properties. ASTM B626 tubes are not only accepted to use in pressure equipment and heat exchanger but are also known within the domestic and international markets.
Alloy Grades Used in ASTM B626 Welded Tubes
The welded tubes of the ASTM B626 are made of nickel and nickel-cobalt and have been chosen to render strength against corrosion, pitting and high-temperature oxidation. Typical grades that are offered by Shubham Metals are:
- UNS N10276 (Hastelloy C-276) - Outstanding chemical attack and stress corrosion cracking.
- UNS N06022 / N06455 / N06200 - Nickel-chromium-molybdenum alloys that are used to provide chemical and thermal resilience.
- UNS R30556 / R20033 - Nickel-cobalt blends, aggressive environment.
The right grade is selected depending on operating temperature, exposure to chemicals and service conditions, which guarantee reliability and longer life cycle in harsh industrial conditions.
Chemical Composition and Mechanical Strength
ASTM B626 welded tubes are very reliable as there is a tight control of chemical composition and mechanical properties. Nickel gives it oxidation and resistance to corrosion, whereas chromium, cobalt and molybdenum improve the strength and thermal stability and resistant to chemical degradation.
