DIN1.4835 253MA UNS S30815 Austenitic Stainless Kub Tiv Thaiv Hlau
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 253 ma yog sib npaug, ua cov hlau ntawm 850 ℃ txog 1100 ℃ qhov kub thiab txias muaj qhov tsim nyog tshaj plaws kev ua tau zoo, muaj peev xwm tiv taus oxidation, oxidation ntawm daim tawv nqaij kub txog 1150 ℃; ntau qhov sib txawv muaj peev xwm nce siab thiab nkag siab tawg lub zog; Feem ntau ntawm cov roj nruab nrab muaj qhov ua tau zoo tiv thaiv kev kub siab corrosion thiab nplai txhuam qhov muaj peev xwm ua tau ntau dua; Muaj peev xwm ua tau ntau dua lub zog thiab tensile lub zog ntawm siab kub.Good formability thiab weldability, thiab txaus rau machinability.
Dhau li ntawm keeb chromium thiab npib tsib xee hlau, 253 ma stainless hlau kuj muaj me me ntawm Rare ntiaj teb Hlau, Tsis tshua muaj lub ntiaj teb cov hlau, REM), thiaj li txhim kho nws cov oxidation tsis kam.Nitrogen ntxiv los txhim kho cov khoom nkag thiab ua kom qhov no ua tiav austenitic. steel.Hauv ntawm chromium thiab npib tsib xee ntsiab lus yog qhov tsawg, tab sis hom steel hlau muaj ntau qhov teeb meem nrog cov hlau siab zoo thiab cov npib tsib xee hlau alloy kub muaj cov yam ntxwv ntawm cov qub.
