ASTM B619 B622 B626 N06455 N06455 Nickel Alloy Pipe Seamless Hastelloy C4 Alloy
Hastelloy C4 Alloy ASTM B619 B622 B626 N06455 alloy is a nickel-chromium-molybdenum alloy with outstanding high-temperature stability as evidenced by high ductility and corrosion resistance even after aging in the 1200 to 1900°F (649 to 1038°C) range. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as welded condition. C-4 alloy also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres up to 1900°F (1038°C)
