Abstract

In a process for treating iron, steel, or their alloys for use in the construction of apparatus exhibiting high resistance to the action of hydrogen or gases containing hydrogen at high temperatures and pressures, the iron &c. is annealed or shaped at a temperature above 650 DEG C. after treatment with hydrogen or gas containing hydrogen at a temperature below the annealing temperature and under an elevated pressure. The annealing may be effected in a saline bath or in an inert atmosphere in a furnace. In an example, tubes of an alloy steel containing 0,15 per cent of carbon, 0,27 of silicon, 0,75 of manganese, 0,32 of molybdenum, and 0,45 of chromium were treated with pure hydrogen in an autoclave at 450 DEG C. and under a pressure of 150 atmospheres for 32 hours and were then annealed in a barium chloride bath at 1050 DEG C.
