1. Kulongedza ndi kofunika kwambiri makamaka ngati katundu wapadziko lonse lapansi amadutsa munjira zosiyanasiyana kuti akafike komwe akupita, chifukwa chake timayika chidwi chapadera pakuyika.
2. Saky Steel's amanyamula katundu wathu m'njira zambiri kutengera zomwe timapanga. Timanyamula katundu wathu m'njira zingapo, monga,
Aloyi ya 253Ma ili ndi izi:
253MA ndi chitsulo chosapanga dzimbiri cha austenitic chosagwira kutentha chomwe chimapangidwira ntchito zomwe zimafuna mphamvu zambiri zokwawa komanso kukana kwa dzimbiri. Kutentha kwake kogwira ntchito ndi 850 ~ 1100 °C.
The mankhwala zikuchokera 253MA ndi moyenera, zomwe zimapangitsa zitsulo kukhala ndi katundu woyenera kwambiri mabuku mu kutentha osiyanasiyana 850 °C-1100 °C, mkulu kwambiri makutidwe ndi okosijeni kukana, ndi sikelo kutentha ndi mpaka 1150 °C; kukana kwambiri kukwawa Kukhoza ndi kukwawa kuphulika mphamvu; kukana bwino kutentha kwa dzimbiri ndi kukana kupaka dzimbiri m'ma media ambiri a mpweya; mphamvu zokolola zambiri ndi mphamvu zolimba pa kutentha kwakukulu; formability wabwino ndi weldability Ndipo machinability zokwanira.
Kuphatikiza pa zinthu zophatikizira chromium ndi faifi tambala, chitsulo chosapanga dzimbiri cha 253MA chilinso ndi chitsulo chochepa kwambiri chapadziko lapansi (Rare Earth Metals, REM), chomwe chimathandizira kwambiri mphamvu yake ya antioxidant. Nayitrojeni amawonjezedwa kuti apititse patsogolo zokwawa ndikupanga chitsulo ichi kukhala austenite wathunthu. Ngakhale kuti chromium ndi nickel zilimo ndizochepa, chitsulo chosapanga dzimbirichi chimakhala ndi kutentha kwakukulu kofanana ndi chitsulo chapamwamba cha alloy alloy ndi alloy-based alloy.
253Ma ntchito:
253MA imagwiritsidwa ntchito kwambiri pazida zopangira sintering, zida zowotcha ng'anjo, kusungunula zitsulo, ng'anjo ndi zida zoponyera mosalekeza, mphero zopukutira (ng'anjo zotentha), ng'anjo zochizira kutentha ndi zina, zida zamchere ndi zida zopangira simenti.
