Lub 304 stainless hlau ntsia hlau yog ib lub voos kheej kheej uas tsis tas siv cov txiv ntoo. Lub xov yog nws tus kheej tapping thiab muaj ib qho taw taub. Thaum cov voos plaub ntawm cov voos kheej kheej ua tus ciav hlau screwed rau hauv lub qhov hauv yas hlau khoom, lawv yuav tsum nias rau hauv lub qhov rau sab nraud thiab tsim ib txoj kev txhim kho txhuam txoj xov txuas.
1) Nws feem ntau yog ua los ntawm carburized steel (99% ntawm tag nrho cov khoom). Nws tuaj yeem ua tau los ntawm cov hlau tsis muaj steel los yog cov hlau uas tsis yog ferrous.
2) 304 stainless hlau screws yuav tsum sov so. Carbon steel self-tapping screws yuav tsum yog carburized thiab stainless hlau screws yuav tsum yog khoom tov hardened. Yog li ntawd tus kheej tapping screws tau raws li tus txheej txheem tus qauv ntawm cov khoom siv thiab kev ua haujlwm.
3) Cov khoom muaj ib qhov chaw siab tawv thiab zoo toughness hauv cov tub ntxhais. Qhov ntawd yog "puab sab nraum zoov xwb." Qhov no yog qhov tseem ceeb ntawm cov hlau tsis muaj hlau tsis muaj kev sib tw. Yog tias cov tawv tawv tsis qis, qhov ntsia hlau tsis tau muab tso rau hauv lub cev puag; Yog hais tias tus tub ntxhais muaj kev txom nyem, lub hau yuav txiav tawm thiab siv tsis tau. Yog li ntawd, "puab lub qhov muag tsis zoo" yog ib lub voos kheej kheej uas txaus siab rau kev ua haujlwm.
4) Cov nplaum ntawm 304 stainless hlau screws xav tau kev tiv thaiv saum npoo, feem ntau plating. Qee cov khoom yuav tsum tau kho phosphate (phosphating). Xws li: phaj phaj nws tus kheej tapping screws feem ntau phosphating.
5) 304 steel hlau tsis muaj cav uas ua rau siv lub tshuab ua haujlwm txias. Nws pom zoo kom siv high-speed txias heading machines thiab high-speed xov rolling cav tov los yog high-speed planetary xov rolling cav tov kom paub cov khoom zoo. Lub taub hau ntawm tus kheej tapping tob hau ua li no yog qhov zoo tsim thiab xov zoo yog siab
