Title:
USE OF A STEEL ALLOY AS A MATERIAL FOR PIPES FOR PRODUCING GAS CYLINDERS, OR AS A MATERIAL FOR PRODUCING MOULDED ELEMENTS IN LIGHT-GAUGE STEEL CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO2003069005
Kind Code:
A8
Abstract:
The invention relates to a steel alloy consisting of between 0.09 and 0.13 % of carbon, between 0.15 and 0.5 % of silicon, between 1.1 and 1.8 % of manganese, a maximum of 0.02 % of phosphorus, a maximum of 0.02 % of sulphur, between 1 and 2 % of chromium, between 0.2 and 0.6 % of molybdenum, between 0.02 and 0.06 % of aluminium, between 0.1 and 0.25 % of vanadium, and iron, the remainder being the usual impurities. The invention especially relates to the use of said steel alloy as a material for pipes which are air-hardened in the presence of inert gas, for producing gas cylinders, or as a material for producing moulded elements in light-gauge steel construction.
