FAQ
Q: Dab tsi yog qhov txawv ntawm 304 thiab 304L txias dov coils?
A: Cov ntsiab lus carbon nyob rau hauv 304 yog capped ntawm 0.08%, thaum nyob rau hauv 304L, nws yog capped ntawm 0.03%. 304L txo qhov kev pheej hmoo ntawm carbide nag lossis daus tom qab vuam, ua kom nws zoo dua haum rau cov khoom uas yuav tsum tau welding nws kim heev. Yog tias koj cov khoom tsis muaj qhov yuav tsum tau muaj kev tiv thaiv corrosion rau cov chaw welded, tus qauv 304 yog qhov kev xaiv zoo dua.
Q: Puas tuaj yeem 304 txias-dov coils tuaj yeem siv rau hauv cov dej ntsev lossis cov ntug dej hiav txwv, ntsev-laden ib puag ncig?
A: Nws tsis pom zoo. Vim tias nws tsis muaj molybdenum, 304 muaj qhov tsis zoo rau chloride-induced pitting corrosion. Rau siv nyob rau hauv marine ib puag ncig los yog dej ntsev media, 316L los yog 2205 duplex stainless hlau yog pom zoo.
Q: Vim li cas 430 stainless hlau pheej yig dua 304?
A: 430 yog ferritic stainless hlau uas muaj yuav luag tsis muaj npib tsib xee. Thaum qhov no zam tus nqi siab ntawm npib tsib xee, nws ua rau tsis zoo formability thiab corrosion kuj piv rau 304; Tsis tas li ntawd, 430 yog hlau nplaum.
Q: Lub sij hawm ua cov hmoov txhuas rau 304 (4-ko taw dav) txias-dov coils yog dab tsi?
A: Rau 4-ko taw dav coils nrog 2B tiav uas muaj nyob rau hauv Tshuag, lub sij hawm txhuas feem ntau yog 3-7 hnub ua hauj lwm. Rau cov coils nrog BA tiav, Tsis muaj . 4 ( txhuam) tiav, lossis cov uas xav tau kev txiav tshwj xeeb, lub sijhawm ua haujlwm yog 12-20 hnub ua haujlwm.
Q: Cov ntaub ntawv dab tsi GNEE muab tom qab xa khoom?
A: Peb muab Mill Test Certificate (MTC), packing list, coj mus muag invoice, thiab daim ntawv pov thawj ntawm keeb kwm. Yog tias koj tau ua haujlwm rau qhov kev tshuaj xyuas thib peb, daim ntawv qhia txog kev tshuaj xyuas thib peb yuav raug muab. Tsis tas li ntawd, txhua qhov kev xa khoom tuaj yeem tsim nyog rau PMI (Positive Material Identification) rov kuaj dua thaum tuaj txog ntawm koj lub tsev khaws khoom.
