Abstract
The base and weld metals of old STFA26 (Cr9Mo) seamless alloy steel tubes, which were put into service at 570 degrees C for 16 000 h, are investigated experimentally. The mechanical properties of the base and weld metals of o ld and new tubes are also examined. The results show that the properties of the STFA26 alloy tubes scarcely have deterioration in long service at 570 degrees C and the tubes can be used in the furnace in the following service , (C) 1999 Elsevier Science Ltd.
