FAQ
Qhov txawv ntawm 347 thiab 347H Stainless hlau yog dab tsi?
Cov tub ntxhais sib txawv ntawm 347 thiab 347H stainless hlau yog lawv cov ntsiab lus carbon. Tsab ntawv "H" sawv cev rau "High Carbon," thiab cov pa roj carbon ntau dua hauv 347H muab kev txhim kho siab - qhov kub thiab txias tsis kam, ua rau nws tsim nyog rau lub sijhawm ntev ntawm qhov kub siab.

347 puas tuaj yeem hloov 321?
Nws tuaj yeem siv los hloov pauv hauv qee qhov xwm txheej, tab sis lawv tsis tuaj yeem hloov pauv dawb. Qhov sib txawv tseem ceeb yog tias 347 muaj qhov zoo tshaj qhov siab tshaj -kub creep thiab kev ntxhov siab- tawg cov khoom piv rau 321; Hauv cov dej num hauv aerospace, txawm li cas los xij, 347 thiab 321 tsis hloov pauv tau, thiab cov kev qhia tshwj xeeb uas tau txib los ntawm OEM (tshwj xeeb yog AMS cov qauv) yuav tsum ua raws li nruj me ntsis.
