Abstract
There are described construction parts for gaseous hydrogen containing media which construction parts are made of a nickel alloy containing 40 to 70% nickel, 15 to 30% chromium, 0 to 20% cobalt, 5 to 10% molybdenum, and 0 to 20% iron and which construction parts have optimum hydrogen permeation prevention properties. For this purpose, the alloys contain 0.5 to 0.8% manganese and the parts are provided with a 1 to 10 .mu.m thick oxide coating by treating at a temperature of 850.degree. to 1000.degree. C. in an oxidizing atmosphere.
