| SAKY STEEL LUB Ntim Khoom: |
1. Kev ntim khoom yog qhov tseem ceeb heev tshwj xeeb tshaj yog thaum xa khoom mus thoob ntiaj teb uas cov khoom xa tuaj dhau ntau txoj kev sib txawv kom mus txog qhov chaw kawg, yog li peb thiaj li txhawj xeeb txog kev ntim khoom.
2. Saky Steel ntim peb cov khoom ntau txoj kev raws li cov khoom. Peb ntim peb cov khoom ntau txoj kev, xws li,
Cov hlau 253Ma muaj cov yam ntxwv hauv qab no:
253MA yog cov hlau austenitic uas tiv taus cua sov uas tsim los rau cov ntawv thov uas xav tau lub zog nkag siab thiab tiv taus corrosion zoo. Nws qhov kub ua haujlwm yog 850 ~ 1100 ° C.
Cov tshuaj lom neeg sib xyaw ntawm 253MA yog qhov sib npaug, uas ua rau cov hlau muaj cov khoom tsim nyog tshaj plaws hauv qhov kub thiab txias ntawm 850 ° C-1100 ° C, tsis kam oxidation siab heev, thiab qhov kub thiab txias yog txog li 1150 ° C; tsis kam nkag siab siab heev Muaj peev xwm thiab lub zog tawg; zoo tiv taus qhov kub thiab txias thiab tiv taus txhuam corrosion hauv feem ntau cov xov xwm gaseous; siab yield zog thiab tensile zog ntawm qhov kub thiab txias; zoo formability thiab weldability Thiab txaus machinability.
Ntxiv rau cov khoom sib xyaw ua ke chromium thiab nickel, 253MA stainless hlau kuj muaj me ntsis ntawm cov hlau tsis tshua muaj (Rare Earth Metals, REM), uas ua rau nws lub peev xwm antioxidant zoo dua. Nitrogen ntxiv rau kom txhim kho cov khoom nkag thiab ua rau cov hlau no ua tiav austenite. Txawm hais tias cov ntsiab lus chromium thiab nickel tsawg, cov hlau tsis muaj stainless no muaj ntau yam zoo ib yam li cov hlau alloyed siab thiab nickel-based alloy.
253Ma daim ntawv thov:
253MA yog siv dav hauv cov khoom siv sintering, cov khoom siv cua sov tawg, cov hlau yaj, lub cub tawg thiab cov khoom siv casting tas mus li, cov tshuab dov (cua sov cua sov), cov cua sov kho cua sov thiab cov khoom siv ntxiv, cov khoom siv hauv av thiab cov khoom siv tsim cement.
