1. Mutha kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
2. Timaperekanso mitengo yotumizira katundu (Reworks, FOB, CFR, CIF, ndi yotsika mtengo). Tikukulimbikitsani kuti mugule katundu woti mutumize katunduyo, zomwe zingakuthandizeni kukhala ndi ndalama zochepa.
3. Zipangizo zomwe timapereka ndi zotsimikizika kwathunthu, kuyambira pa satifiketi yoyesera zinthu zopangira mpaka chiganizo chomaliza cha kukula kwake. (Malipoti adzawonetsedwa pakufunika)
4. Tikutsimikizira kuti tipereka yankho mkati mwa maola 24 (nthawi zambiri mu ola lomwelo)
5. Mutha kupeza njira zina zogulira zinthu, kutumiza zinthu ku fakitole ndi kuchepetsa nthawi yopangira zinthu.
6. Tadzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutafufuza njira zonse, sitidzakusokeretsani polonjeza zinthu zabodza zomwe zingapangitse ubale wabwino ndi makasitomala.

1. Mayeso a Kuwona kwa Miyeso
2. Kuyang'ana kwa makina monga kukoka, Kutalikitsa ndi kuchepetsa malo.

1. Kulongedza katundu ndikofunikira kwambiri makamaka pankhani yotumiza katundu kunja kwa dziko komwe katundu amadutsa m'njira zosiyanasiyana kuti akafike komwe akupita, choncho timaika chidwi chathu chachikulu pa kulongedza katundu.
2. Saky Steel amanyamula katundu wathu m'njira zosiyanasiyana kutengera zinthuzo. Timanyamula katundu wathu m'njira zosiyanasiyana, monga,

Aloyi wa 253Ma ali ndi makhalidwe awa:
253MA ndi chitsulo chosapanga dzimbiri cha austenitic chosagwira kutentha chomwe chapangidwira ntchito zomwe zimafuna mphamvu zambiri zoyenda komanso kukana dzimbiri. Kutentha kwake kogwira ntchito ndi 850~1100 °C.
Kapangidwe ka mankhwala ka 253MA ndi koyenera, zomwe zimapangitsa kuti chitsulocho chikhale ndi mphamvu zokwanira zogwirira ntchito bwino pa kutentha kwa 850 °C-1100 °C, kukana kwambiri okosijeni, ndipo kutentha kwa sikelo kumafika 1150 °C; kukana kwambiri kukwera ndi kuphulika kwa kukwera; kukana bwino ku dzimbiri kutentha kwambiri komanso kukana kuzizira kwa burashi m'malo ambiri osungira mpweya; mphamvu yogwira ntchito kwambiri komanso mphamvu yokoka kutentha kwambiri; kupangika bwino komanso kusinthasintha. Ndipo makina okwanira.
Kuwonjezera pa zinthu zosakaniza chromium ndi nickel, chitsulo chosapanga dzimbiri cha 253MA chilinso ndi chitsulo chochepa cha rare earth metals (Rare Earth Metals, REM), chomwe chimawonjezera mphamvu yake yolimbana ndi ma antioxidants. Nayitrogeni imawonjezedwa kuti ikonze mphamvu zoyambira ndikupanga chitsulochi kukhala austenite yonse. Ngakhale kuti chromium ndi nickel zili zochepa, chitsulo chosapanga dzimbirichi chili ndi makhalidwe ambiri ofanana ndi chitsulo cha alloy chopangidwa ndi alloy komanso nickel-based alloy.

Mapulogalamu a 253Ma:
253MA imagwiritsidwa ntchito kwambiri pazida zoyeretsera, zida zophulitsira ng'anjo, kusungunula zitsulo, zida zoyeretsera ng'anjo ndi zoponyera mosalekeza, ma rolling mill (ma heating furnaces), ma heating furnaces ndi zowonjezera, zida za mchere ndi zida zopangira simenti.
