Dab tsi yog 316 Stainless Hlau thiab Nws Cov Txheej Txheem Tshuaj

Q1: Dab tsi yog cov khoom tseem ceeb ntawm 316 stainless hlau? A1: Cov khoom tseem ceeb yog 16% -18% chromium (Cr), 10% -14% npib tsib xee (Ni), 2% -3% molybdenum (Mo), nrog carbon (C) cov ntsiab lus tsawg dua lossis sib npaug li 0.08% thiab lwm yam kab kawm xws li silicon thiab manganese.

Q2: Vim li cas molybdenum ntxiv rau 316 stainless hlau? A2: Molybdenum tuaj yeem tsim ib qho MoO₄²⁻ passive zaj duab xis nrog chloride ions, uas thaiv cov tshuaj chloride ion yaig thiab txhim kho pitting corrosion kuj ntawm 316 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv high -chloride ib puag ncig.

Q3: Dab tsi yog qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm 316 thiab 304 stainless hlau? A3: 304 stainless hlau muaj ib tug muaj pes tsawg leeg ntawm 18Cr-8Ni tsis muaj molybdenum, thaum 316 ntxiv 2% -3% molybdenum nyob rau hauv lub hauv paus ntawm 304, thiab nws cov ntsiab lus nickel yog me ntsis siab dua (10% -14% vs 8%).

Q4: Puas yog cov ntsiab lus carbon ntawm 316 stainless hlau cuam tshuam rau nws txoj haujlwm? A4: Yog lawm, cov ntsiab lus carbon (tsawg dua lossis sib npaug li 0.08%) cuam tshuam rau nws qhov kev ua haujlwm vuam thiab corrosion kuj; Cov ntsiab lus qis dua (xws li 316L, Tsawg dua lossis sib npaug li 0.03%) tuaj yeem ua kom zoo dua kom tsis txhob muaj kev cuam tshuam ntawm intergranular tom qab vuam.

Q5: Lub teb chaws tus qauv code sib raug rau 316 stainless hlau hauv Suav teb yog dab tsi? A5: Suav teb chaws tus qauv code rau 316 stainless hlau yog 0Cr17Ni12Mo2, thiab rau 316L nws yog 022Cr17Ni12Mo2.
