316 Stainless Hlau:Anustenitic Stainless hlau (tsis muaj sib nqus, lub ntsej muag-chaw sau lo lus teb lo lus teb). Lub ntsiab sib xyaw: 16-18% CR, 1 0}}}}}} Cov khoom ua pov thawj zoo heev thiab tsis yog sib nqus tom qab tov anertinging.
416R Stainless Hlau:Martensitic Stainless Hlau (ntxiv dag zog los ntawm kev kho cua sov, sib nqus). Cov khoom siv raug: 12-14% cr, tsawg dua los yog sib npaug ntawm {}}. 15%}. 15%}. 15%}. 15%}. 15%}. 15%}. 15%}. 15%}. 15%} Lub microstructure yog martensitic, nrog lub hardness thiab lub zog adjustable ntawm quenching thiab tempering.
2. 316 Stainless hlau vs 416R: Tshuaj lom neeg muaj pes tsawg leeg
| Lub ntsiab | 316 Stainless Hlau | 416R Stainless Hlau |
|---|---|---|
| Chromium (cr) | 16-18% (hauv paus ntawm corrosion tsis kam) | 12-14% (qis dua hauv paus tiv thaiv corrosion corrosion) |
| Npib tsib caug (ni) | 10-14% (Ruaj Khetenite, Acid Refunse) | Ze li tsis muaj (tus nqi qis dua, tsis muaj lub roj cig stabilization) |
| Molybdenum (mo) | 2-3% (Txhim Kho Pitting Kuj) | Tsis muaj |
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 08% (cov pa roj carbon tsawg, tiv thaiv kev txhim kho corrosion) | Tsawg dua los yog sib npaug rau {0. 15% (ntau dua carbon, ua rau kev kho cua sov los ntawm kev kho cua sov) |
| Sulphur (s) | Tsawg dua lossis sib npaug rau 0. 03% (cov ntsiab lus) | {{{{{0}}}}. 15-0.35% (siab faj sulfur txhim kho tesinity) |
3. 316 Stainless Hlau vs 416R: Cov Khoom Siv Neeg Kho Tshuab
316 Stainless Hlau:
Chav Chav Kub Tensile Lub zog: ntau dua lossis sib npaug rau 515 MPa
Paib lub zog: ntau dua los yog sib npaug rau 205 MPa (anealed mob)
Elongation: ntau dua los yog sib npaug rau 40%
Hardness: tsawg dua los yog sib npaug rau 95 hrb
Qhov Zoo:Kev nyuaj heev thiab kev cuam tshuam tsis kam. Haum rau tsawg rau qhov kub kub (tsawg dua los yog sib npaug rau 600 degree). Zoo tshaj Weldability (tsis muaj kev kho kom sov-weld).
416R Stainless Hlau:
Chav Chav Chav Kub Tensile Lub zog: ntau dua lossis sib npaug zos rau 735 MPa (tom qab quenching thiab tempering)
Paib lub zog: ntau dua los yog sib npaug rau 540 MPa
Elongation: ntau dua los yog sib npaug rau 12%
Hardness: 20-30 hrc (kho tau ntawm kev kho cua sov)
Qhov Zoo:Yuav tuaj yeem ua tau lub zog loj los ntawm kev kho cua sov. Cov Sulfur cov ntsiab lus muab nws cov hlau-zoo li machinability (txo lub cuab tam, muaj kev txuag siab), txawm hais tias nws muaj qis dua.
4. 316 Stainless hlau vs 416r: corrosion tsis kam
316 Stainless Hlau:
Due to its Mo content, it offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking-especially in chloride-containing environments (eg, seawater, brine) and organic acids (eg, formic, acetic acids). Dav siv hauv kev ua tshuaj, cov tubrog nkoj, khoom noj, thiab tshuaj.
416R Stainless Hlau:
Corrosion tsis kam tsuas yog me ntsis zoo dua li cov roj carbon steel. Cov ntsiab lus qis dua thiab muaj cov leej faj (uas tuaj yeem tsim cov sulfide suav) nce txoj kev pheej hmoo ntawm cov muaj kev pheej hmoo ntawm corrosion. Tsis tsim nyog rau cov av noo lossis acidic ib puag ncig. Qhov zoo tshaj plaws siv nyob rau hauv cov huab cua qhuav los yog qhov chaw tiv thaiv corrosion tsis yog qhov kev txhawj xeeb thawj.
5. 316 Stainless Hlau vs 416R: Kev kho cua sov thiab kev kho cua sov
316 Stainless Hlau:
Feem ntau siv nyob rau hauv kev daws teeb meem-anealed mob (muag tom qab annealing). Lub zog tuaj yeem txhim kho los ntawm kev ua haujlwm txias (ua haujlwm hnyav), tab sis nws tsis tuaj yeem ua haujlwm hnyav los ntawm kev kho cua sov.
416R Stainless Hlau:
Hardenable los ntawm quenching (~ 1000 degree) thiab tempering (200-600 degree). Piv txwv li, quenching tuaj yeem tsa lub hardness mus ~ 35 hrc, thaum tempering txo nws mus rau ~ 25 hrc txhawm rau txhim kho kev nruj. Zoo heev ticting tshuab mns suav nrog kev pab uas zoo rau cov lathes thiab precision part machining (piv txwv, cov ntsia hlau, lub zog, cov khoom siv valve).
6. Cov ntawv thov
316 Stainless Hlau:
Siv rau hauv cov kav dej siv tshuaj lom neeg, cov khoom siv kho mob, cov khoom siv kho mob, cov khoom siv khoom noj khoom haus, thiab cov khoom siv ua khoom noj uas muaj kev ua siab loj yuav tsum muaj.
416R Stainless Hlau:
Qhov zoo tshaj plaws rau kev siv tshuab xws li high-precision bolts, thiab ntsuas lub zog yog xav tau, thiab corrosion tsis kam yog tsis tseem ceeb.
