Fabrication

 

Qib 904L stainless hlau yog cov hlau purity siab nrog cov ntsiab lus tsis muaj leej faj. Lawv tuaj yeem raug machined siv txhua txoj hauv kev. Cov qhab nia no tuaj yeem hloov kho tau yooj yim rau ib lub vojvoog me me hauv qhov txias. Txawm hais tias tom qab annealing tsis tas yuav tsum tau nyob rau hauv feem ntau, nws yuav tsum tau nqa tawm thaum lub fabrication yog ua nyob rau hauv kev nyuaj siab heev corrosion cracking tej yam kev mob.
