High-Temperature Corrosion Resistance of Welded Joints in Sanicro 25 Steel

Article Preview

Abstract:

The trials conducted in sulfur– and chlorine–rich environment were aimed at simulating the conditions prevalent in operating power boilers. The tests conducted in the temperatures of 700°C and 750°C have been selected in such a way as to enable reference between them and the supercritical parameters of boiler steam. The analysis of the rate of high–temperature corrosion kinetics in the Sanicro 25 steel was carried out for up to 3000 hours. The aim of the tests was to establish the oxidation kinetics and evaluate the destruction of the new generation of Sanicro 25 steel in atmosphere containing Cl and S in temperature of 700°C and 750°C during up to 3000 hours of operation.
