12Cr2MoWVTiB boiler tubeyog ib qho qis-alloy bainitic cua sov-resistant steel. Nws tsuas yog siv tungsten-molybdenum composite solid tov ntxiv dag zog, vanadium-titanium composite dispersion ntxiv dag zog rau thiab kab boron hardening. Cov hlau muaj cov khoom zoo tshaj plaws hauv kev ua haujlwm tsawg dua 600 degree. Mechanical zog, antioxidant zog thiab cov ntaub so ntswg stability.
12Cr2MoWVTiB seamless boiler raj Hom hlau no muaj lub zog thermal zoo ntawm 620 degree, txawm tias nce mus txog qib ntawm qee cov chromium-nickel austenitic steels, tab sis nws cov oxidation kuj poob qis, thiab nws qhov hnyav nce hauv ib cheeb tsam hauv 3000h yog 242g. / m2, tus nqi corrosion yog 0. 15mm / xyoo.
12Cr2MoWvTiB seamless steel yeeb nkab rau high-pressure boilers yog tsuas yog siv los tsim high-pressure kav, ntim, flanges, li qub thiab lwm yam khoom nyob rau hauv high-pressure boilers, petrochemical kev lag luam, nuclear zog thiab lwm yam teb.

Kev tshuaj xyuas tsis muaj kev puas tsuaj
Cov kav hlau yuav tsum raug kuaj xyuas qhov tsis zoo ntawm ultrasonic ib los ntawm ib qho raws li cov kev cai ntawm GB / T5777. Lub longitudinal groove qhov tob qib ntawm kev sib piv cov qauv yeeb nkab rau kev kuaj xyuas ultrasonic flaw yog C5. Raws li qhov yuav tsum tau ua ntawm tus neeg yuav khoom, lwm yam kev tshuaj xyuas tsis muaj kev puas tsuaj tuaj yeem ntxiv tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom thiab tau teev tseg hauv daim ntawv cog lus.
Tensile test qauv
Rau cov kav hlau uas muaj lub taub sab nraud tsawg dua 219 hli, qhov kev ntsuas tensile yuav tsum tau ua raws li qhov ntev ntawm cov yeeb nkab steel. Rau cov yeeb nkab steel nrog ib txoj kab uas hla tsis pub tsawg tshaj 219 hli, thaum cov yeeb nkab steel loj tso cai, qhov kev ntsuas tensile yuav tsum tau ua raws cov kev taw qhia ntawm cov yeeb nkab steel. Thaum qhov loj ntawm cov yeeb nkab steel tsis txaus los ua qhov kev ntsuas kev sib tw, qhov kev ntsuas tensile yuav tsum tau ua raws li qhov ntev ntawm cov yeeb nkab steel. kev kuaj.
