Alloys resistant to localized corrosion, hydrogen sulfide stress cracking and stress corrosion cracking

摘要

An alloy and a metal product characterized by resistance to localized corrosion, hydrogen sulfide stress cracking (hydrogen embrittlement) and stress corrosion cracking at temperatures up to about 200° C. consisting essentially of nickel 40-65%, cobalt 0-5%, chromium 10-20%, molybdenum 12- 18%, iron 10-20%, tungsten up to 5%, carbon 0-0.1% manganese up to 3%, vanadium up to 1% and silicon up to 0. 2%. The alloy resistance is maintained when it is cold worked over 20%.
