316L thiab 316LN stainless hlau tsum chaw tsim tshuaj paus,tiv tauj pebkom tau txais kev tsocai dawb thiab qauv!
Thawj qhov sib txawv ntawm316L thiab 316LN stainless hlaunyob rau hauv lawv cov ntsiab lus nitrogen thiab nws cov teebmeem ntawm lawv cov khoom. Ob lub alloys yog 316 series ntawm austenitic stainless hlau, uas paub txog lawv cov corrosion kuj thiab zoo txhua yam khoom. Nov yog qhov kev sib piv ntxaws:
Qhov txawv tseem ceeb:316 AWV 13
Cov ntsiab lus Nitrogen: Qhov txawv tseem ceeb
AISI 316L (1.4404 / 1.4335): Muaj cov ntsiab lus carbon tsawg heev (tsawg dua lossis sib npaug li 0.03%) los tiv thaiv carbide nag lossis daus thiab txhim kho weldability.
AISI 316LN (1.4406 / 1.4429): Muaj cov ntsiab lus tsawg tsawg li 316L tab sis nrog cov ntsiab lus nitrogen ntxiv ntawm 0.10-0.16%.
Chemical Composition & Qib Equivalents (UNS S31653 vs S31603)
| Feature | 316L (Cov pa roj carbon tsawg) | 316LN (Nitrogen Enhanced) |
| Nitrogen ntsiab lus | < 0.10% | 0.10% - 0.22% |
| Yield zog (min) | 170 - 200 MPa | 280 - 300 MPa |
| Ductility ntawm Cryogenic | Nruab nrab | Tshwj xeeb |
| Zoo tshaj rau | General Chemical / Marine | Nuclear / Tsawg-Temp / Siab-Npaum |
Mechanical Strength: 316LN vs 316L
Ntxiv cov nitrogen hauv316 SIB 31653 nce lub alloy yield thiab tensile zog piv rau 316L S31603. Nitrogen ua raws li tus neeg sawv cev ntxiv dag zog los ntawm kev txhim kho lub austenitic stability ntawm cov hlau, muab cov khoom zoo dua qub.
Kev sib piv Corrosion Resistance
Ob leegAlloy 316L thiab 316LNmuab kev tiv thaiv corrosion zoo heev hauv ntau qhov chaw, nrog rau cov chaw hauv hiav txwv thiab chloride. Txawm li cas los xij, muaj nitrogen hauv 316LN tuaj yeem txhim kho pitting thiab crevice corrosion kuj me ntsis piv rau 316L.
Weldability thiab Fabrication
Ob qib raug suav hais tias muaj qhov zoo weldability. Cov ntsiab lus tsis tshua muaj carbon nyob rau hauv ob qho tib si txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum lub sij hawm vuam, uas tuaj yeem ua rau intergranular corrosion. Qhov sib ntxiv ntawm nitrogen hauv 316LN pab tswj lub zog hauv thaj tsam weld.
Daim ntawv qhia: Thaum twg yuav hloov mus rau 316LN?
Stainless hlau 316L: Feem ntau siv hauv kev lag luam chemical thiab petrochemical, kev ua zaub mov, khoom siv tshuaj, thiab kev siv dej hiav txwv.
Stainless hlau 316LN UNS S31653: Siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj zog dua thiab txhim kho corrosion kuj, xws li nuclear reactor Cheebtsam, cryogenic hlab ntsha, thiab siab - ib puag ncig siab.
FAQ
Q: Puas tuaj yeem 316LN hloov 316L?
Yog lawm, 316LN tuaj yeem hloov 316L nyob rau hauv feem ntau qhov yuav tsum muaj zog dua lossis zoo dua cryogenic toughness, txawm tias nws los ntawm tus nqi siab dua.
Q: Puas yog 316LN sib nqus?
Tsis yog, nws tsis yog magnetic. Vim muaj qhov ruaj khov ntawm nitrogen, qhov sib nqus permeability ntawm 316LN tseem qis heev - txawm tias tom qab ua haujlwm txias - ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov cuab yeej precision.
Q: Dab tsi yog qhov txawv ntawm 316LN thiab 316L?
Cov ntsiab lus nyob hauv nitrogen. 316LN nta cov ntsiab lus nitrogen ntxiv; thaum khaws cov khoom qis -carbon, nws lub zog tawm los yog kwv yees li 60% siab dua li ntawm 316L.
