| Sei Uchifanira Kusarudza Isu: |
1. Unogona kuwana zvinhu zvakakwana zvinoenderana nezvaunoda nemutengo wakaderera.
2. Tinopawo mitengo yeReworks, FOB, CFR, CIF, uye mitengo yekutumira zvinhu pamba nepasuo. Tinokukurudzira kuti uite dhiri rekutumira zvinhu iro richave rakachipa.
3. Zvinhu zvatinopa zvinogona kusimbiswa zvizere, kubva pachitupa chebvunzo yezvinhu zvisina kugadzirwa kusvika pachirevo chekupedzisira. (Mishumo icharatidzwa pazvinodiwa)
4. Tinovimbisa kupa mhinduro mukati memaawa makumi maviri nemana (kazhinji muawa imwe chete)
5. Unogona kuwana dzimwe nzira dzekugadzira zvinhu, kutumirwa kwezvinhu mumigodhi nekuderedza nguva yekugadzira.
6. Takazvipira zvizere kuvatengi vedu. Kana zvikasakwanisika kuzadzisa zvinodiwa zvenyu mushure mekuongorora sarudzo dzese, hatizokutsausei nekuita zvipikirwa zvenhema izvo zvinogadzira hukama hwakanaka nevatengi.
| Kuvimbiswa Kwemhando yeSAKY STEEL (kusanganisira Inoparadza Neisina Kuparadza): |
1. Bvunzo reKuona
2. Kuongorora michina sekudhonza, Kureba uye kuderedza nzvimbo.
3. Kuongorora kukanganisa
4. Kuongorora makemikari

| Kurongedza kwaSAKY STEEL: |
1. Kurongedza kwakakosha zvikuru kunyanya kana zvinhu zvichitumirwa kunze kwenyika, zvinhu zvinopinda nenzira dzakasiyana-siyana kuti zvisvike kunzvimbo yekupedzisira, saka tinonyanya kufunga nezvekurongedza.
2. Saky Steel inorongedza zvinhu zvedu nenzira dzakasiyana-siyana zvichibva pazvigadzirwa. Tinorongedza zvigadzirwa zvedu nenzira dzakasiyana-siyana, dzakadai se,
Chiumbwa che253Ma chine hunhu hunotevera:
253MA isimbi isingatsvi inodziya uye inodzivirirwa kubva mukupisa, yakagadzirirwa kushandiswa inoda simba rakawanda uye inodzivirira ngura zvakanaka. Tembiricha yayo yekushanda ndeye 850~1100 °C.
Kuumbwa kwemakemikari e253MA kwakaenzana, izvo zvinoita kuti simbi ive nehunhu hwakakodzera hwakakwana muhurefu hwekupisa hwe850 °C-1100 °C, kuramba kupisa kwe oxidation kwakanyanya, uye tembiricha yechiyero inosvika 1150 °C; kuramba kupisa kwe creep kwakanyanya Simba rekukwira nekukwira; kuramba kupisa kwe creep kwakanyanya uye kuramba kupisa kwe brush mu gaseous media zhinji; simba guru rekukora uye simba rekusunga pakupisa kwakanyanya; kugona kuumbwa zvakanaka uye kusveta uye kugona michina yakakwana.
Pamusoro pezvinhu zvinosanganisa chromium nenickel, 253MA simbi isina tsvina inewo simbi shoma isingawanzoitiki (Rare Earth Metals, REM), iyo inovandudza zvakanyanya kugona kwayo kurwisa mabhakitiriya. Nitrogen inowedzerwa kuti ivandudze hunhu hwe creep uye kuita kuti simbi iyi ive austenite yakakwana. Kunyangwe zviri mukati mechromium nenickel zvakaderera, simbi iyi isina tsvina ine hunhu hwakafanana nesimbi ine alloy yakawanda uye nickel-based alloy.
253Ma mafomu:
253MA inoshandiswa zvakanyanya mumidziyo yekupisa, michina yekupisa, simbi inonyungudutsa, michina yekupisa nemidziyo inoenderera mberi, mill inotenderedza (mafurnace ekupisa), mafurnace ekupisa nezvinhu zvinowedzerwa, michina yezvicherwa nemidziyo yekugadzira simende.
