Dab tsi yog Cov Khoom Siv Stainless Hlau 321?

Cov khoom siv dab tsi yog stainless hlau 321

Ti nyob rau hauv 321 stainless hlau muaj nyob rau hauv ib tug stabilizing lub caij, tab sis nws kuj yog ib tug kub-lub zog steel, uas yog zoo dua li 316L nyob rau hauv kub kub. 321 stainless hlau muaj qhov zoo abrasion tsis kam hauv cov organic thiab inorganic acids ntawm qhov sib txawv thiab qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv oxidizing media, thiab yog siv rau hauv kev tsim cov khoom hnav-resistant acid ntim thiab hauv ob sab phlu ntawm cov khoom hnav-resistant thiab cov kav dej thauj mus los.

321 stainless hlau yog Ni-Cr-Ti austenitic stainless hlau, nws cov kev ua tau zoo heev zoo ib yam li 304, tab sis vim yog ntxiv ntawm titanium hlau, thiaj li hais tias nws muaj kev tiv thaiv zoo rau grain ciam corrosion thiab kub siab zog. Vim yog qhov sib ntxiv ntawm titanium hlau, nws tswj tau qhov tsim ntawm chromium carbide.
