07Ni5DR steel phaj yog steel phaj rau ultra-low-temperature ntim, uas yog siv los tsim ultra-low-temperature thawv steel daim hlau rau LNG tso tsheb hlau luam rau khaws cia thiab thauj liquefied natural gas (LNG) thiab LNG nkoj. Qhov twg 07 hais txog cov ntsiab lus nominal carbon ntawm 0.07% hauv cov phaj hlau thiab Ni5 yog hais txog cov ntsiab lus Ni ntawm 5% hauv cov phaj hlau.
07Ni5DR steel qib los ntawm ob tus lej ntawm cov ntsiab lus nruab nrab ntawm cov pa roj carbon monoxide, cov cim cim nickel thiab cov ntsiab lus nruab nrab ntawm cov hlab ntsha uas tsis muaj qhov kub thiab txias, "tsawg" thiab "muaj peev xwm" ntawm lo lus ntawm thawj cov tsiaj ntawv ntawm Hanyu Pinyin "DR" Composition.
07Ni5DR (5Ni) yog dav siv nyob rau hauv sib sib zog nqus txias sib cais ua, huab cua sib cais, liquefied petroleum gas cia chaw tsim khoom, 07Ni5DR (5Ni) nyob rau hauv xyoo tas los no, lub domestic thee chemical kev lag luam tej yaam num nyob rau hauv lub CO2 absorption ntauwd, H2S absorption ntauwd, H2S concentration. ntauwd, methanol scrubbing ntauwd thiab lwm yam khoom siv kub kub yog siv nyob rau hauv ib tug loj tus naj npawb ntawm cov khoom tsim.
