Abstract (en)
[origin: WO2019207157A1] The present invention relates to low alloy steels with a high yield strength that present an improved sulphide stress cracking behaviour. The present invention also relates to tubular products, such as tubes or pipes, made from said steel, as well as a process for manufacturing such tubular products. In addition, the present invention concerns use of such tubular products for well drilling and/or for production, extraction and/or transportation of oil and gas.
