Vim li cas S31254 yog ib qho tseem ceeb?

254 SMO khwv tau nws "Super Austenitic" xwm txheej vim nws cov meticulously sib piv siab-alloy muaj pes tsawg leeg:

• High Chromium (CR ~ 20%): Qhia cov hauv paus tsis kam rau oxidation thiab dav dav corrosion .
• Siab npib tsib (NI ~ 18%): Txav ruaj khov ntawm cov qauv Austenic (tsis sib nqus, muaj kev cuam tshuam rau kev ntxhov siab (SCC).
• High Molybdenum (MO ~ 6%): Ua kom muaj dej tsis sib thooj, tshwj xeeb yog cov tshuaj noj hiav txwv, tshwj xeeb, cov tshuaj ua kom zoo, thiab txheej txheem tshuaj lom.
• Nitrogen (n ~ 0 {{. 2%): Ua kom tau zoo txhim kho pitting aws. nws ua synergistically nrog molybdenum.
• Tooj liab (cu ~ {0.7-1%): ntxiv rau txhim kho kev tsis kam mus rau sulfuric acid .
