Cov hauv qab no yog cov lus qhia ntxaws ntxaws uas cov menyuam yaus lub thermos khob 304 thiab 316 muaj kev nyab xeeb dua, thiab qhov txawv ntawm 316 stainless hlau thiab 304.

Ob leeg 316 stainless hlau thiab 304 yog austenitic stainless hlau, tab sis tseem muaj qhov sib txawv no:
1. Cov muaj pes tsawg leeg yog txawv. Qhov nruab nrab nickel ntsiab lus ntawm 316 stainless hlau yog 12%, thaum nruab nrab nickel ntsiab lus ntawm 304 stainless hlau yog tsawg, txog 9%.
2. Lub siab kub tsis kam yog qhov sib txawv, vim tias cov ntsiab lus nickel ntawm 316 stainless hlau yog ntau dua, yog li qhov kub tsis kam ntawm 316 stainless hlau muaj zog ntau dua li ntawm 304. 304 stainless hlau muaj qhov kub tsis kam ntawm 800 degrees, thaum 316 stainless hlau muaj qhov kub thiab txias ntawm 1200 txog 1300 degrees.
3. Lub corrosion kuj yog txawv. Piv nrog 304 stainless hlau, 316 stainless hlau ntxiv 2% ntau molybdenum, yog li qhov corrosion kuj ntawm 316 stainless hlau yog siab dua li ntawm 304 stainless hlau.
4. Tus nqi sib txawv. Tus nqi ntawm 316 stainless hlau yog kim dua li ntawm 304 stainless hlau.
Feem ntau hais lus, cov me nyuam lub khob thermos 304 thiab 316 muaj kev nyab xeeb, thiab ob qho tib si yog cov zaub mov qib stainless hlau, uas tuaj yeem xaiv raws li qhov xav tau tiag tiag.

Qhov twg zoo dua, 304 lossis 316 stainless hlau thermos rau cov menyuam mos, 304 lossis 316 rau cov menyuam mos
