Ua ntej tshaj plaws, muaj qhov sib txawv ntawm cov khoom xyaw. 316L yog cov pa roj carbon tsawg, thiab L txhais tau tias cov pa roj carbon tsawg, yog li cov ntsiab lus ntawm 316L cov khoom siv qis dua li ntawm 316 cov khoom. Qhov thib ob, qhov kev tiv thaiv corrosion yog txawv. 316L stainless hlau muaj kev tiv thaiv zoo rau cov qoob loo ciam teb corrosion thiab zoo dua los tiv thaiv corrosion thiab tiv thaiv xeb. Lub zog ntawm ob cov ntaub ntawv kuj txawv. Lub zog ntawm 316L cov khoom yog qis dua li ntawm 316, ua kom yooj yim rau kev ua haujlwm. Tsis tas li ntawd, welded seem ntawm 316 stainless hlau yuav tsum tau kho tom qab vuam annealing, thaum 316L stainless hlau tsis.
1. Cov khoom xyaw sib txawv
316 Tshuaj muaj pes tsawg leeg (%): C Tsawg dua lossis sib npaug rau 0.08, Si Less dua lossis sib npaug rau 1.00, Mn Tsawg dua lossis sib npaug rau 2.{{ 6}}, P Tsawg dua lossis sib npaug rau 0.035, S Tsawg dua lossis sib npaug rau 0.03, Ni Tsawg dua lossis sib npaug rau 10.0-14 .0, Cr Tsawg dua lossis sib npaug rau 16.0-185, Mo Less dua lossis sib npaug rau 2.0-3.0.
316L tshuaj muaj pes tsawg leeg (%): Cs0.03, Si Less dua los yog sib npaug rau 1.00, Mn Less dua los yog sib npaug rau 2.00, P Tsawg dua lossis sib npaug rau 0.035, S Tsawg dua lossis sib npaug rau 0.03, Ni Tsawg dua lossis sib npaug rau 10.0-14.0, Cr Less tshaj lossis sib npaug rau 16.0-185, Mo Less dua lossis sib npaug rau 2.0-3.0
2. Muaj qhov sib txawv ntawm hom
316 qib: Qib qub yog 0Cr17Ni12Mo2, thiab qib tshiab yog 06C17N12M2, uas yog Asmeskas tus qauv TP316 thiab Japanese tus qauv SUS316.
316L hom: Lub npe qub yog 00Cr17Ni14Mo2, hom yog 022C17N12M2, uas yog tus qauv TP316L thiab tus qauv Japanese SUS316L.
3. Muaj qhov sib txawv ntawm kev siv zog
Yield zog: 316 khoom yog 210 (N / MM2), 316L khoom yog 18O (N / MM2).
Tensile zog: 316 khoom yog 520 (N / MM2), 316L khoom yog 48O (N / MM2)
Lub zog ntawm 316L cov khoom yog qis dua li ntawm 316 cov khoom, ua kom yooj yim rau kev ua haujlwm.
4. Txawv corrosion kuj
316L stainless hlau muaj kev tiv thaiv zoo rau intergranular corrosion thiab zoo dua los tiv thaiv corrosion thiab tiv thaiv xeb.
