INCOLOY ALLOY 800H SB-407-N08810/N08811 PIPE

Alloy 800H Pipe, ASTM B407 Alloy 800H Pipe, Alloy 800H Seamless Pipe, UNS N08810 Pipe, Incoloy 800H Pipe, 1.4958 Pipe, 1.4876 Pipe.

ASTM B407 Alloy 800H Seamless Pipe product is a nickel molybdenum chromium superalloy with the addition of tungsten, designed for excellent corrosion resistance in a wide range of harsh environments. This nickel alloy resists the formation of grain boundary deposits in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded state. The chemical and petrochemical processing industries use these UNS N08810 welded pipes for heat exchangers and other piping systems in nitric acid media, especially where resistance to chloride stress corrosion cracking is required. Power plants use them for superheater and reheater piping.

Alloy 800H Seamless Pipe is manufactured in accordance with international standards ASTM B407, ASME SB407,  they ensure that the pipe meets the required specifications and quality standards. The seamless pipe production method involves heating a billet of metal to a certain temperature and then rolling it into a hollow tube. The tube is then subjected to various finishing processes such as annealing, pickling, and polishing to give it the desired properties and surface finish.

The chemical composition of Alloy 800H Seamless Pipe includes 30-35% nickel, 19-23% chromium, 0.05-0.1% carbon, 8-10.5% iron, and other trace elements. This composition gives it the desired properties such as resistance to oxidation, corrosion, and high-temperature strength.
