Cov phaj hlau no paub txog nws cov khoom siv kho tshuab zoo heev. Nws muaj qhov sib npaug zoo ntawm lub zog thiab ductility, ua rau nws haum rau ntau yam kev siv. Lub zog ntawm SS400 steel phaj tso cai rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab, thaum nws cov ductility ua rau nws tuaj yeem khoov, tsim, thiab welded yam tsis muaj kev tawg.

 

Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, SS400 steel phaj muaj ib tug nruab nrab ntawm carbon thiab lwm yam alloying ntsiab. Qhov no ua rau nws tsim nyog lub zog thiab hardness thaum tuav zoo weldability thiab machinability. Cov tshuaj muaj pes tsawg leeg tshwj xeeb tuaj yeem hloov kho kom tau raws li qhov yuav tsum tau ua ntawm cov ntawv thov sib txawv.

 

Cov txheej txheem tsim khoom ntawm SS400 steel phaj suav nrog kub dov thiab tswj kom txias. Qhov no ua rau muaj qhov sib xws microstructure thiab cov khoom siv kho tshuab zoo ib yam thoob plaws hauv lub phaj. Cov txheej txheem kub dov kuj tseem cuam tshuam qee qhov kev ntxhib los mos ntawm qhov chaw, uas tuaj yeem muaj txiaj ntsig zoo rau cov ntawv thov uas yuav tsum muaj adhesion lossis tuav.

 

SS400 steel phaj muaj nyob rau hauv ntau yam thicknesses thiab ntau thiab tsawg, ua rau nws haum rau ntau yam kev siv. Nws tuaj yeem txiav tau yooj yim, drilled, thiab welded kom tau raws li cov kev xav tau ntawm cov haujlwm sib txawv. Tsis tas li ntawd, nws tus nqi qis dua piv rau qee yam khoom siv ua rau nws xaiv kev lag luam rau ntau daim ntawv thov.

 

Hauv kev tsim kho kev lag luam, SS400 steel phaj feem ntau yog siv rau cov khoom siv xws li kab teeb, kab, thiab daim hlau. Nws lub zog thiab kav ntev ua rau nws zoo tagnrho rau kev txhawb nqa hnyav thiab tiv taus ib puag ncig hnyav. Hauv kev lag luam tsim khoom, nws yog siv los ua cov khoom siv, cov cuab yeej, thiab cov khoom siv.

 

Hauv kev xaus, SS400 steel phaj yog cov khoom siv ntau yam thiab txhim khu kev qha nrog cov khoom siv zoo heev, tus nqi tsim nyog, thiab muaj ntau yam. Txawm hais tias siv hauv kev tsim kho, kev tsim khoom, lossis lwm yam kev lag luam, nws tseem ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv.
