Daim ntawv thov ntawm Carbon Steel ASTM A283 Qib C & D
1. Lub tsev tsim
Vim nws lub zog muaj zog thiab zoo toughness, A283 Qib C & D Phaj tuaj yeem siv los tsim cov kab, kab, kev txhawb nqa thiab lwm yam tseem ceeb hauv kev tsim vaj tsev. Nws tuaj yeem tiv taus cov khoom loj thiab muaj kev ua haujlwm zoo seismic kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov tsev.
2. Machinery manufacturing
Nyob rau hauv lub tshav pob ntawm mechanical manufacturing, no steel phaj enables tsim ntau yam khoom siv thiab qhov chaw, xws li lub zog, ncej, bearing rooj, thiab lwm yam. Nws zoo mechanical zog thiab machining zog ua rau nws muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm ntau yam complex duab thiab precision.
3. Lub nkoj siab
Tsim cov hlab ntsha siab xws li cov tso tsheb hlau luam, cov kav dej, thiab lwm yam. Cov khoom siv no yuav tsum tau tiv taus qee qhov kev ntxhov siab sab hauv thiab sab nraud, yog li cov khoom siv yuav tsum muaj lub zog siab thiab zoo toughness.
4. Kev tsim khoom nkoj
Cov phaj hlau no tuaj yeem tiv taus ntau yam loads thiab corrosion nyob rau hauv Marine ib puag ncig, ua kom muaj kev nyab xeeb kev nyab xeeb thiab kav ntev ntawm lub nkoj.
5. Kev tsim kho choj
Raws li ib qho tseem ceeb ntawm kev thauj mus los, Choj yuav tsum tau nqa cov khoom loj thiab cov xeev nyuaj. Vim nws lub zog siab thiab zoo toughness, A283 steel tuaj yeem siv los tsim cov khoom tseem ceeb xws li cov kab teeb tseem ceeb thiab cov piers ntawm Choj.
