Abstract

A method of manufacturing tubing from a well-defined steel composition. in particular fat a suited gas inflator pressure vessel comprises the steps: a) producing a steel tubing from a steel composition including at least one hot rolling or hot forming pass: b) subjecting the steel tubing to a cold-drawing process to obtain desired dimensions. wherein the cold-drawing process comprises at least too pulls and before the first pull of the cold-drawn tug process an intermediate austenizing and quenching step: c) subsequently performing a final recovery heat treatment on the cold-drawn steel tubing at a temperature in the range of 200-600° C.
