Abstract (en)
[origin: US4772337A] A compress gas container is made from Austenite steel alloy and is later strengthened or stabilized by cryo-deformation. The Austenite steel alloy is a metastable CrNi steel with a combined titanium and niobium content no greater than 0.02% by weight and a carbon content no greater than 0.045% by weight. With the nickel content up to 9.5% by weight, the carbon content is between 0.03% to 0.045%; and with the nickel content between 9.5% and 10%, the carbon content is below 0.03%.
