Baoshan Iron& SteelCo., Ltd., Shanghai201900, China;2. SuzhouNuclearPowerResearch Institute, Suzhou215004, Jiangsu, China)Abstract: The test and evaluation of T92 steel for high pressure boiler tubes produced byBaosteelwere made, focusing on its welding process performance and welded joint properties.Meanwhile, T92 steelwas tested aswelded joints of the power plant boiler tubes. The creep-rupturestrength of those joints was also tested and estimated. The results indicated that the weldingperformance and each technical index of thewelding joints canmeet the requirements ofDL/T 868)2004 standard. Theoperation stability of thewelded joints is good, and the creep-rupture strength ofthose joints in service for one year still reaches or surpasses the requirement byGB 5310) 2008 andEN 10216) 2007 standards as awhole.Keywords: T92 stee;l welding property tes;t welded jointyw = 1977M3 2005M8ZvCVY! 26647280E-mail xujianhao baostee.l com0 -2006MSn(USC)?Fg,S7SA-213 T92S=QVVabT921T91PM,S=XgT925#ok,iT925/bz?7?T91QV5kT925b5wAzoVF-4, T92WFPoVoYu3DM8_9v,AhMboh)e1p,HyWFPF9v,B9F)e4,yNA1ST92o#h?k53 / 2011M1,sNST925o?bLVI_oh?KzZT,K1o?S,yNT925hLLV_#1Mk,5S4/ 1b1 o?k1. 1 k53SA) 213 T925,?48. 3 8. 5 mmb1. 2 oHq1. 2. 1 焊接材料SThermanitMTS 616LHo,?2. 4b99. 99%Bbb1. 2. 2 焊接工艺条件oZEGTAW;gT( 60b ? 5b)V;oo;We200e/,;N;oe10 14 kJ/cm,oHWxe;o)o)( 760 ? 10) e 60m inbV1 ossTable 1 Chemical composition of theweldingwire %wC wSi wMn wP wS wCr wMo wV wCu wNb wN wW wN i0. 10 0. 29 0. 68 0. 010 0. 008 9. 11 0. 35 0. 17 0. 02 0. 057 0. 062 1. 64 0. 421. 3 kZEi%GGB /T 228) 20025i%kZE6,MTS- 880Ak,FMq2mm /min,HqyP%9,k? 0. 5%;%vGB /T 4338) 20065%kZE6,e,%kboh?kvDL/T 868) 20045o?6,ivT92?+,9F?a4kb2 oh?s2. 1 ?oh?kTnV2bi?VT92S1p,DL/T 868) 20045o?6,FySX#=54T /P92(m1a2)MbV2 oh?kTTable 2 Test results ofmechanicalproperties ofwelded jointsk/eI|Rp0. 2 /MPa Rm /MPa A /%!iCL-1 505 710 14. 5CL-2 500 710 18. 0(502 710 16. 2 )580CL-1 345 400 24. 5CL-2 325 380 23. 0(335 390 23. 8 )600CL-3 310 340 25. 5CL-4 315 340 25. 0(312 340 25. 2 )625CL-5 265 315 21. 5CL-6 280 305 24. 5(272 310 23. 0 )i 4401) 6201) 201) )1)ASME SA213 T921pb54许建豪等 T925o?k#ohN图 1 瓦卢瑞克#曼内斯曼钢管公司T /P92钢屈服强度曲线Fig. 1 Tensile strength curves ofT/P92(V&M )2. 2 4+GDL/T 884) 20045M_/56T92ohM_,sY_ua%uaYuo4F,Tnm3b图 2 瓦卢瑞克#曼内斯曼钢管公司T /P92钢抗拉强度曲线Fig. 2 Y ield strength curves ofT/P92(V&M )huFhf8F,%u10),Yu8)bA/hn#VF+,n#F,9?Cff8F,DL/T 868) 2004S1pb图 3 焊接接头各区域显微组织Fig. 3 M icrostructure of thewelded joint( each zone)2. 3 _o_AwLk,k!z,Duramin- 101A9vGB /T 4340. 1) 1999 5fkZE6kbk200 g,FHW
