S32760 imagwirizana kwambiri ndi F55 ndi EN 1.4501. Komabe, tsatanetsatane wa chinthucho uyenera kutsimikiziridwabe chifukwa miyezo ya mbale, miyezo yopangira zinthu ndi zofunikira pa polojekiti zingasiyane.
Kodi mbale ya S32760 ikhoza kulumikizidwa?
Inde, mbale ya S32760 ikhoza kulumikizidwa pogwiritsa ntchito njira yolumikizira yoyenerera. Kulowetsa kutentha, kutentha kwa interpass, kusankha zodzaza ndi kuyeretsa pambuyo pa weld kuyenera kulamulidwa kuti zisunge kukana dzimbiri komanso kukhala bwino kwa gawo.
Kodi ndi zinthu ziti zomaliza pamwamba zomwe zilipo?
Zomaliza zomwe zimafala kwambiri ndi Nambala 1, zophikidwa mu uvuni, 2B ndi malo opukutidwa. Kupezeka komaliza kumadalira makulidwe, njira yopangira, komanso zomwe makasitomala amafuna.
Kodi PMI ikupezeka pa mbale ya S32760?
PMI ikhoza kukonzedwa ikafotokozedwa kuti ithandize kutsimikizira kudziwika kwa alloy isanatumizidwe. Iyenera kugwiritsidwa ntchito limodzi ndi kuwunika kwa MTC, osati ngati njira yolowera m'malo mwa kusanthula kwa mankhwala a labotale.
Kodi MTC ndi EN 10204 3.1 zingaperekedwe?
SAKY STEEL ikhoza kupereka zikalata za MTC ndi EN 10204 3.1 malinga ndi dongosolo logulira. Malipoti ena owonjezera a kukula, PMI, makina kapena UT angakonzedwenso ngati atchulidwa.
