SUS347 H stainless hlau bar

SUS347 (347/S34700/0Cr18Ni11Nb) yog ib hom hlau uas muaj austenitic stainless hlau nrog kev tiv thaiv zoo rau kev xeb siv lead ua.
Nws muaj kev tiv thaiv corrosion zoo hauv cov kua qaub, alkali thiab ntsev kua, thiab muaj kev tiv thaiv oxidation zoo thiab weldability hauv huab cua hauv qab 800 ° C. 347 stainless hlau muaj kev ua haujlwm zoo heev ntawm kev kub siab tawg (Kev Nyuaj Siab Rupture) thiab kev kub siab creep tiv thaiv kev ntxhov siab mechanical zog zoo dua 304 stainless hlau. Siv dav hauv aviation, hluav taws xob tsim, chemistry, petrochemical, zaub mov, ntawv thiab lwm yam teb.
