1. Iwe unogona kuwana iyo yakakwana zvinyorwa zvinoenderana nezvinodiwa zvaunoda pamutengo madiki mukana.
2. Isu tinopawo reworks, fob, cfr, cif, uye gonhi kumitengo yekutakura mitengo. Isu tinokuzivisa kuti uite chekuita nekutumira izvo zvichave zvehupfumi chaizvo.
3. Izvo zvigadzirwa zvatinopa zvakazara zvose, kurudyi kubva pakurisa zvinyorwa zvekutarisa chitupa kune yekupedzisira dimensional chirevo. (Mishumo icharatidza pane zvinodiwa)
4. E Guarantee kupa mhinduro mukati memakumi maviri nemaviri (kazhinji munguva imwe chete)
5. Iwe unogona kuwana dzimwe nzira dzekutengesa, mill inoburitsa nekuderedza nguva yekugadzira.
6. Isu takazvipira zvizere kune vatengi vedu. Kana zvikasakwanisa kuita zvaunoda mushure mekuongorora zvese zvingasarudzwa, isu hatizokutsausha nekuita zvipikirwa zvekunyepa izvo zvichagadzira zvakanaka vatengi hukama.
| Saky Steel mhando vimbiso (kusanganisira zvese zvinoparadza uye zvisiri zvekuparadza): |

1. Kukwirisa kwakakosha zvakanyanya mune imwe nyaya yekuvandudzwa kwenyika mukati meizvokuita mari dzakasiyana siyana kuti usvike kunzvimbo yekupedzisira, saka isu tinoisa hanya chaiyo maererano nekutora.
2. Sky steel kurongedza zvinhu zvedu munzira dzakawanda dzinoenderana nezvigadzirwa. Isu tinorongedza zvigadzirwa zvedu munzira dzakawanda, dzakadai,
Iyo 253ma Alloy ine inotevera hunhu:
253ma ndeyekupisa-kupokana Austenitic simbi yakagadzirirwa kuti zvinyoreso zvaida simba rakakwira righroke uye rakanakisa kupesana. Yayo yekushandisa tembiricha ndeye 850 ~ 1100 ° C.
Kuumbwa kwemakemikari 253ma kuri pakati nepakati, kunoita kuti simbi ive yakakwana yakazara munzvimbo dzevakasarudzika ye850 ° C, yakanyanya kukwikwidza overdation kuramba, uye tembiricha yekudziya inosvika 110 ° c; zvakanyanya kukwira kukosora kukanganisika uye kukosora simba simba; Kunetseka kwakanaka kune yakakura tembiricha corroson uye kuramba kuBrash Corroson mune yakawanda yakawanda midhiya; Simba rakakwirira rakabiwa uye simba rakafanana nekupisa kukuru; Kuumbwa kwakanaka uye welding uye yakakwana michina.
Pamusoro pezvinhu zvekunyepedzera Chromium neNickel, 253ma Stainless ine huwandu hushoma hwesimbi yepasi pevhu (risingawanzo simbi, r RM), rinovandudza zvakanyanya antioxidant kugona. Nitrogen inowedzerwa kuti uvandudze creep zvivakwa uye ita iyi simbi ive yakazara Austenite. Kunyangwe iyo Chromium neNickel Zviri Mukati zvakanyanyisa, iyi simbi isina simba ine akawanda ezvimiro zvakakura zvekupisa seyeakakwira alloy alloy simbi neNickel-based alloy.
253MA application:
253Munoshandiswa zvakanyanya mumidziyo inotadza, kuputika kwemidziyo, chirahwe, chiviridzo chekudzinga, zvinopisa zvirongwa), zvipfeko zvekurapa, zvimishini, zvemichero uye zvigadzirwa zvemumentction.
