The ultimate strength of boiler pipe metal made of martensitic chromium steel grade T91 is studied. Test results are close to European standard data. A dependence for calculating life characteristics of heat recovery boiler superheaters is obtained. It is shown that compared with domestic steel grade 10Kh9ÌFB of the same class T91 grade steel ultimate strength is higher. This discrepancy is related to the different nature of the steel structure.
