18MnMoNbR steel phaj belongs rau nruab nrab thiab qis kub thiab siabboiler nkoj steel phaj, raws li GB713-2014 tus qauv, 18 yog carbon cov ntsiab lus ntawm 0.18%; Mn yog cov khoom siv tshuaj uas muaj qee yam tshuaj manganese; Mo yog cov khoom siv tshuaj uas muaj qee yam tshuaj molybdenum; NB yog niobium; R yog thawj tsab ntawv ntawm lub thawv phaj.
Kev xa khoom ntawm 18MnMoNbR steel phaj: ib txwm xa hauv ib txwm muaj + tempered xwm txheej (tempering kub yuav tsum tsis txhob qis dua 620 degree). Nrog rau kev tso cai ntawm tus neeg thov, yog tias lub thickness ntau dua 60mm, nws tuaj yeem xa tuaj rau hauv cov txheej txheem annealed lossis tempered.
Qhov tso cai sib txawv ntawm qhov loj, cov duab thiab qhov hnyav ntawm 18MnMoNbR steel phaj yuav tsum ua raws li cov kev cai ntawm GB / T 709, thiab qhov tso cai sib txawv ntawm thickness yuav tsum ua raws li chav kawm B sib txawv ntawm GB / T 709.
Lub pob, cim thiab daim ntawv pov thawj zoo ntawm 18MnMoNbR steel phaj yuav tsum ua raws li GB / T 247.

GNEE tau pab cov neeg siv khoom hauv ntau dua 50 lub teb chaws (North America, Europe, Southeast Asia, Middle East, thiab lwm yam) thiab tau txais kev nplua nuj nyob rau hauv cov nqe lus lag luam thoob ntiaj teb (FOB, CIF, EXW) thiab cov kev cai hauv zos. Peb cov kev sib txuas lus tau zoo (Lus Askiv, Mev, Arabic kev txhawb nqa) thiab cov txheej txheem kev lag luam pob tshab ua rau kev sib koom tes zoo thiab tsis muaj teeb meem - dawb.
