Dab tsi yog qhov sib txawv ntawm 1.4301 stainless hlau thiab 304? Thaum yuav cov ntaub ntawv stainless hlau, ntau tus neeg yuav ntsib cov lus nug no: yog 1.4301 thiab 304 stainless hlau tib cov khoom? Tuaj yeem 1.4301 stainless hlau thiab 304 hloov ib leeg? Puas muaj qhov sib txawv hauv kev ua haujlwm lossis tus nqi?
Kab lus no yuav pab cov neeg yuav qhia meej cov ntsiab lus ntawm cov qauv ntawm cov qauv, kev ua tau zoo, thov kom tsis muaj ntawv pov thawj rau cov khoom xaiv.
1. 1.4301 Tus Hlau Stainless thiab 304: Cov Qauv
| Lub npe | Txheem | Cov Cheeb Tsam Siv Ntau |
|---|---|---|
| 1.4301 | EN 10088 (European Txuj Ci) | Teb chaws Europe, Tuam Tshoj (rau export rau cov teb chaws Europe) |
| 304 | AISI / ASTM (Asmeskas tus qauv) | North America, kev ua lag luam thoob ntiaj teb hauv Asia |
Ob leeg muaj lub18-8 ustenitic stainless hlau tsev neeg, muaj kwv yees li 18% chromium thiab 8% npib tsib xee. Lawv tau siv dav hauvCov khoom siv hauv chav ua noj, kev ua zaub mov noj, kev lag luam architectural, thiab khoom siv kho mob.
2. 1.4301 stainless hlau vs.304: Tshuaj lom neeg muaj pes tsawg leeg
| Lub ntsiab | 1.4301 (en) | 304 (AISI) |
|---|---|---|
| CR (chromium) | 17.5–19.5% | 18.0–20.0% |
| Ni (npib tsib) | 8.0–10.5% | 8.0–10.5% |
| C (carbon) | Tsawg dua los yog sib npaug rau 0. 07% | Tsawg dua los yog sib npaug rau 0. 08% |
| Mn, si, s, p | Cov nyiaj txiag lw; tswj tsis pub dhau kev txwv zoo sib xws |
3.1.4301 stainless hlau vs.304: Cov Khoom Siv Neeg Kho Tshuab Sib Piv
| Ntiag tug | 1.4301 (En cov qauv, annealed) | 304 (ASTM Txheem, Annealed) | Cov lus hais txog qhov sib txawv |
|---|---|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 520 mpa | Ntau dua los yog sib npaug rau 515 MPa | Me ntsis sib txawv hauv cov qauv kev pab tsawg kawg, tab sis cov qoob loo ntau zaus feem ntau tau muab 520-700 mpa rau ob qho tib si; Qhov txawv yog qhov tsis txaus ntseeg. |
| Paib lub zog | Ntau dua los yog sib npaug rau 215 MPa | Ntau dua los yog sib npaug rau 205 MPa | En txheej txheem rau 1.4301 yog qhov siab dua me ntsis, tab sis tom qab ua (piv txwv li, kev tsim kho txias, qhov tseem ceeb yog sib piv. |
| Elongation | Ntau dua los yog sib npaug rau 40% | Ntau dua los yog sib npaug rau 40% | Qhov zoo tib yam, qhia tau tias kev pib ua kom zoo nkauj thiab kev haum rau cov qauv sib dhos ua ke thiab vuam. |
| Hardness (HBW) | Tsawg dua los yog sib npaug rau 187 | Tsawg dua los yog sib npaug rau 187 | Tib yam hauv annealed mob. Cov haujlwm txias yuav ua rau qhov sib txawv me me, tab sis tsis txaus los cuam tshuam interchangeability. |
| Elastic modulus | Tom ntej no 200 GPA | Tom ntej no 200 GPA | Qhov zoo tib yam, qhia tib lub cev txhav txhav thiab cov qauv kev ruaj ntseg. |
| Poisson tus piv | 0.28 | 0.28 | Qhov zoo tib yam, xav txog tib qho kev tawm tsam tshwj xeeb (piv ntawm transverse mus rau kev sib tw ntev). |
| Qaug zog muaj zog | 200-330 mpa | 210-440 MPa | 304 tej zaum yuav muaj kev qaug zog me ntsis, tab sis hauv kev siv cov ntawv thov, qhov sib txawv yog qhov tsawg thiab muaj mob. |
Rau kev ua tiav, lo lus nug tseem ceeb yog: tuaj yeem 1.4301 stainless hlau thiab 304 raug siv sib hloov pauv? Nws puas yuav cuam tshuam cov khoom lag luam zoo lossis ntawv pov thawj?
1. Sib txuas lus nyob rau hauv cov engentional thiab khoom lag luam: ntev li ntev tau yog tus neeg siv khoom tshwj xeeb lossis cov qauv haujlwm tau pom zoo, 1.4301 thiab 304 tuaj yeem suav hais tias cov ntaub ntawv sib npaug.
2. Cov haujlwm tshwj xeeb yuav tsum tau ua tiav raws li kev kos duab lossis ntawv pov thawj: piv txwv li, yog tias txoj haujlwm export rau Tebchaws Europe yuav tsum tau teev tseg; Yog tias nws tau txais raws li ASTM cov qauv, 304 yuav tsum tau cim.
