ASTM B619 Nickel Alloy Tubes and Pipes for Heat Exchangers
Introduction
Nickel alloys are widely used in various industrial applications due to their exceptional resistance to corrosion and high-temperature stability. ASTM B619 covers welded nickel and nickel-cobalt alloy pipes, specifically designed for heat exchangers. This article delves into the specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades of the following nickel alloys:
- UNS N06455 (C-4)
- UNS N10675 (B-3)
- UNS N10276 (C276)
- UNS N06022 (C22)
- UNS N06035 (G35)
Material Specification
ASTM B619 specifies the requirements for welded nickel and nickel-cobalt alloy pipes intended for use in heat exchangers. These materials are known for their excellent resistance to various forms of corrosion, including pitting, crevice corrosion, and stress-corrosion cracking.
Key Features
