Magwaro emhando yepamusoro anowanikwa anogona kusanganisira EN 10204 3.1 MTC, marekodhi ePMI, mishumo yehukuru, mishumo yekuyedza hydrostatic kana kuti isingaparadze, marekodhi ekupisa uye magwaro ekuongorora evamwe vanhu zvichienderana nezvinodiwa pakutenga.

Chii chinonzi 347 Stainless Steel Tube?

Simbi isingatsvi 347 isimbi ye chromium-nickel alloy inogadzikiswa ne niobium, inotsanangurwawo mune mamwe matsananguro uchishandisa izwi rekuti columbium. Niobium ine simba rakasimba rekabhoni kupfuura chromium. Munguva yekugadzira inodzorwa uye kupisa kunotevera, inoumba niobium carbides dzakagadzikana, zvichibatsira kuchengetedza chromium pedyo nemiganhu yezviyo.

Kugadzikana uku kunokosha nekuti simbi isina kugadzikana yeaustenitic inogona kugadzikana mushure mekunamira kana kugara kwenguva refu pakupisa kuri pakati nepakati. Ma chromium carbides anogona kudonha pamiganhu yezviyo, zvichiita kuti nzvimbo dzakapera chromium dzive panjodzi yekuora pakati pegranular. Giredhi 347 inoderedza njodzi iyi kana chemistry, kupisa uye maitiro ekugadzira zvikadzorwa nemazvo.
