A process for the preparation of Alloy austenitic Stainless Steel Tubes to be used in high temperature applications.

摘要

Method for preparing Alloy austenitic Stainless Steel Tubes.Wherein is preparing an alloy formed by 0.02 to 0.08% by weight of carbon, 1.5 to 2.5% by weight of manganese by 0.5 to 1.0% by weight of Silicon by 0.02 to 0.08% by weight of Phosphorus by 0.004 to 0010% by weight of Sulphur by 12.5 to 14.5% in weight Chromium, 14.5 16.5% in Weight d And nickel by 1.5 to 2.5% by weight of Aluminum, 0.002 to 0.008% in weight devoured by 0.1 to 0.4% by weight of Titanium, zirconium and residual contents of Vanadium, niobium, Tantalum, Copper, nitrogen, Oxygen, Cobalt, arsenic and Iron impurities; because the sum of the weight percent Phosphorus plus the percentage by weight of the weight percentage of Sulphur, Boron is above 0,03% by weight; and because the relationship between the weight of porcenmtaje in you and the sum of the percentages by weight of Carbon and Nitrogen is included between 4 and 6.
