1. Unogona kuwana zvinhu zvakakwana maererano nezvinodiwa zvako pamutengo wakaderera.
2. Isu tinopawo Reworks, FOB, CFR, CIF, uye mitengo yekutumira pamusuwo kumasuo. Tinokupa zano kuti uite dhiri yekutumira iyo inove ine mari shoma.
3. Zvishandiso zvatinopa zvinonyatso zivikanwa, kubva pazvitupa zvekuedza kusvika kune yekupedzisira dimensional statement.(Mishumo icharatidza pane zvinodiwa)
4. inovimbisa kupa mhinduro mukati memaawa makumi maviri nemana (kazhinji muawa imwe chete)
5. Unogona kuwana dzimwe nzira dzemasheya, kutakura zvigayo nekuderedza nguva yekugadzira.
6. Isu takazvipira zvizere kune vatengi vedu. Kana zvisingabviri kuzadzisa zvaunoda mushure mekuongorora zvese zvingasarudzwa, isu hatizokunyengedzi nekuita zvipikirwa zvenhema izvo zvinogadzira hukama hwakanaka hwevatengi.

1. Visual Dimension Test
2. Mechanical bvunzo senge tensile, Elongation uye kuderedzwa kwenzvimbo.
3. Kuongorora kwemigumisiro
4. Kemikari yekuongorora kuongorora
5. Kuoma bvunzo
6. Pitting kudzivirira bvunzo

1. Kurongedza kwakakosha zvakanyanya muchiitiko chekutumira kune dzimwe nyika uko kutakurwa kunopfuura nemumatanho akasiyana-siyana kuti usvike kwaunoenda, saka tinoisa hanya zvakanyanya maererano nekurongedza.
2. Saky Steel inorongedza zvinhu zvedu nenzira dzakawanda zvichienderana nezvigadzirwa. Isu tinorongedza zvigadzirwa zvedu nenzira dzakawanda, senge,

Iyo 253Ma alloy ine zvinotevera maitiro:
253MA isimbi isingadziviriri austenitic stainless simbi yakagadzirirwa maapplication anoda kusimba kwepamusoro uye kunaka kwekusagadzikana. Kupisa kwayo kwekushanda kuri 850 ~ 1100 °C.
Kemikari ye253MA yakaenzana, izvo zvinoita kuti simbi ive neyakakodzerwa yakazara midziyo mutembiricha ye850 °C-1100 °C, yakanyanya kukwirira oxidation kuramba, uye tembiricha yekuyera inosvika 1150 ° C; yakakwirira kwazvo inokambaira Kugona uye zvinokambaira kuputika simba; kupikisa kwakanaka kune yakakwirira tembiricha corrosion uye kuramba kubhurashi corrosion mune yakawanda gaseous media; kusimba kwegoho repamusoro uye kusimba kwesimba pakupisa kwakanyanya; yakanaka formability uye weldability Uye zvakakwana machinability.
Pamusoro peiyo alloying element chromium uye nickel, 253MA Stainless simbi zvakare ine shoma shoma yepasi simbi (Rare Earth Metals, REM), iyo inovandudza zvakanyanya antioxidant kugona kwayo. Nitrogen inowedzerwa kunatsiridza zvinokambaira uye kuita iyi simbi ive austenite yakakwana. Kunyangwe zviri mukati mechromium nenickel zvakati dzika, simbi isina tsvina iyi ine akawanda emhando yetembiricha yepamusoro seyepamusoro alloy alloy simbi uye nickel-based alloy.

253Ma zvikumbiro:
253MA inoshandiswa zvakanyanya mumidziyo yekupisa, blast furnace midziyo, simbi inonyunguduka, choto uye inoenderera ichikandira midziyo, inokungurutsa mill (zviyo zvekudziya), mavira ekupisa kupisa uye zvishongedzo, zvicherwa zvemichina uye simende zvigadzirwa zvekugadzira.
