ASTM B626 Nickel-Cobalt Alloy Tube For Industry

Material Specification

ASTM B626 covers welded nickel and nickel-cobalt alloy tubes intended for general corrosion-resisting and low- or high-temperature service. The specification includes several UNS designations, each representing a unique alloy with distinct properties suitable for various industrial applications.

Key Features

Corrosion Resistance: These alloys offer excellent resistance to a wide range of corrosive environments, including acidic, alkaline, and chloride-containing atmospheres.
High-Temperature Performance: Suitable for high-temperature applications due to their stability and strength at elevated temperatures.
Versatility: Can be used in various industries, including chemical processing, power generation, and oil and gas.

Chemical Composition

The chemical composition of these alloys is critical to their performance. Below is a table summarizing the typical chemical composition for each UNS designation:

Element	UNS N08031	UNS R30556	UNS N06230	UNS N06686	UNS R20033
Nickel (Ni)	30.0-32.0%	20.0-22.5%	55.0-65.0%	57.0-71.0%	30.0-35.0%
Chromium (Cr)	26.0-28.0%	22.0-24.0%	20.0-24.0%	20.0-23.0%	31.0-35.0%
Molybdenum (Mo)	6.0-7.0%	2.5-4.0%	1.0-2.0%	15.0-17.0%	2.0-3.0%
Iron (Fe)	27.0-29.0%	Balance	3.0% max	4.0% max	20.0-25.0%
Cobalt (Co)	0.5% max	15.0-20.0%	5.0-15.0%	2.5% max	1.0% max

Mechanical Properties
