| Saky Steel thawv ntim: |
1. Cov Packing yog qhov tseem ceeb tshaj plaws tshwj xeeb tshaj yog nyob rau hauv cov kev xa khoom thoob ntiaj teb nyob rau hauv kev txiav txim siab dhau los ntawm ntau qhov kawg, yog li peb txo kev txhawj xeeb tshwj xeeb txog kev ntim.
2. Saky steel ntim pob peb cov khoom hauv ntau txoj hauv kev raws li cov khoom. Peb ntim peb cov khoom hauv ntau txoj kev, xws li,
Lub 253ma alloy muaj cov yam ntxwv hauv qab no:
253Ma yog cua sov ua kom sov Austenitic stainless hlau tsim rau cov ntawv thov lub zog loj thiab zoo corrosion tsis kam. Nws cov kev ua haujlwm kub ntau yog 850 ~ 1100 ° C.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 253ma yog qhov ua rau cov hlau muaj qhov uas tsim nyog tshaj plaws ntawm qhov ntsuas kub ntawm 850 ° C, thiab ntsuas kub siab txog li 1150 ° C; Tsis tshua muaj neeg coob heev muaj peev xwm thiab nkag dag zog rau lub zog; Zoo tsis kam mus rau qhov kub siab thiab tiv thaiv kom txhuam corrosion hauv feem ntau geebalous media; Muaj lub zog muaj zog thiab tensile lub zog ntawm kev kub siab; Fedability zoo thiab weldability thiab txaus machinability.
Ntxiv nrog rau cov ntsiab lus alloying chromium thiab npib tsib xee, 253mA stainless hlau kuj muaj cov me me ntawm lub ntiaj teb tsis tshua muaj hlau, rem), uas txhim kho nws lub peev xwm antioxidant. Cov nitrogen ntxiv rau txhim kho cov khoom loj thiab ua kom cov hlau no ua tiav Austenite. Txawm hais tias cov chromium thiab cov neeg chickel tsawg, cov hlau tsis muaj zog muaj ntau tus cwj pwm siab uas yog cov hlau loj sib cais hlau thiab npib tsib xee.
253ma cov ntawv thov:
253ma yog siv dav hauv Sintering cov cuab yeej, tawg ua kom yooj yim cov khoom, rolling mills (rolling castaces thiab cov khoom siv cua sov (cov khoom siv cua sov (cov khoom siv cua sov thiab cov khoom siv kub.
