FAQ
Q: Puas yog 316L yeeb nkab xav tau kev kho cua sov tom qab vuam?
A: Tsis yog. 316L muaj cov ntsiab lus carbon tsawg dua los yog sib npaug li 0.03%, tshem tawm qhov kev pheej hmoo ntawm kev xeb ntawm intergranular. Tshaj tawm -weld solution annealing yog qhov tsis tsim nyog, ua kom yooj yim rau ntawm - cov txheej txheem roj thiab roj thiab txo cov nqi.
Q: 316L stainless hlau puas tuaj yeem siv rau hauv qhov chaw acidic uas muaj hydrogen sulfide?
A: Yog lawm, hauv kev pabcuam me me thaum ua raws li NACE MR0175 cov cai.
Q: Cov kev kho deg twg yog muaj?
A: Cov kav dej yog muab los ntawm cov khoom noj khoom haus thiab cov khoom noj khoom haus (dawb nyiaj -dawb). Bright annealing (BA qib), mechanical polishing rau 400 # lossis 600 # tiav, lossis ib ntus los tiv thaiv- xeb txheej raws li xav tau. Rau thaj chaw welded, ua ntej -grooved beveling tiv thaiv kuj tau teev tseg.
