X42 yeeb nkab yog qib dab tsi?
X42 steel yeeb nkab ntog nyob rau hauv PSL1 thiab PSL2 qib pipeline steel hauv API 5L tus qauv, nrog rau qhov tsawg kawg nkaus lub zog ntawm 290 MPa thiab tensile zog ntawm 415 -760 MPa. Cov hlau no yog tsim los ntawm micro- alloying tsim thiab tswj dov thiab txias txheej txheem, ua rau zoo{11}}grained microstructure thiab cov khoom zoo li qub. Tshwj xeeb tshaj yog, X42 steel yeeb nkab qhia tau zoo heev uas tsis tshua muaj - kub toughness, tuav zoo cuam tshuam toughness ntawm -20 degree, ua rau nws zoo heev rau siv nyob rau hauv cov cheeb tsam txias. Tsis tas li ntawd, cov yeeb nkab steel tau dhau los ua qhov tsis zoo{16}} kuaj kev puas tsuaj, suav nrog kev kuaj ultrasonic thiab kev tshuaj ntsuam xyuas tam sim no, kom ntseeg tau tias lub cev tsis muaj qhov tsis xws luag thiab ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb rau kev sib kis siab.
