Mechanical properties of forged 10.5% Cr steels tested within cost 501, round 2, WP3 - final report projects 3S1

Technical Report:

Abstract

ABB Stal has contributed to the programme of COST 501, round 2, work package 3, by performing mechanical test on three trial melts (D1, D1.2 and E2) and on material taken from two full scale rotors (rotor E and rotor F). The aim has been to develop more heat resistant 12% Cr steels with a creep resistance of 100 MPa at 600 degrees C and 10{sup 5}h. This report describes the tensile, toughness and creep properties achieved in these steels in the as received conditions and after ageing treatments. The investigated steel show a considerable improvement in creep strength compared to conventional 12% Cr steels. The best results were obtained for steel E2 which is likely to meet the creep goal. Different ageing treatments and overageing does not influence these steels detrimentally. Long term creep properties are kept and only a minor increase in FATT{sub 50} temperature is observed. 10 figs, 6 tabs
