301 Stainless hlau thiab 304 Stainless hlau: Qhov sib txawv sib txawv thiab Ntawv Xaiv
Tso lus
Ntawm cov ntaub ntawv stainless hlau, 301 thiab 304 thiab 304 yog ob hom kev sib tw ntawm stainless hlau me me, uas tau siv dav hauv ntau qhov kev lag luam thiab lub neej txhua hnub. Txawm hais tias lawv yuav zoo ib yam li cov tsos, lawv txawv nyob rau hauv composition, kev ua tau zoo thiab siv. Hauv qab no peb yuav tshawb txog qhov kom paub qhov txawv li cas kom paub qhov txawv ntawm cov hlau los ntawm 304 stainless hlau, thiab uas ib qho zoo dua.
301 Stainless hlau thiab 304 Stainless Hlau: Tshuaj lom neeg muaj pes tsawg leeg
| Teem nqi | CR (chromium) | Ni (npib tsib) | C (carbon) | Lwm Ntsiab Lus | Crystal Qauv |
|---|---|---|---|---|---|
| 301 | 16-18% | 6-8% | Tsawg dua los yog sib npaug rau 0. 15% | - | AUSTENITIC |
| 304 | 18-20% | 8-10.5% | Tsawg dua los yog sib npaug rau 0. 08% | - | AUSTENITIC |
Qhov sib txawv:
CR-NI synergy: 304 muaj kev sib xyaw ua ke nrog K + NI ntsiab lus ntawm {3}}. 5% siab dua 301, sib sau ua ib qho kev ua yeeb yaj kiab ntau dua.
Carbon tswj: 301 cov cov ntsiab lus carbon tau yog ze li ntawm 304, ua kom nrawm dua ua haujlwm txias tab sis nce kev pheej hmoo ntawm cov nag lossis daus thiab huab cua hauv lub sijhawm vuam.
301 Stainless hlau thiab 304 Stainless hlau: Corrosion Kuj
1. Ntsev Tshuaj Ntsuam Sib Haum (ASTM B117 Txuj Ci)
301: Liab xeb tshwm nyob rau hauv 48 teev hauv 5% NacL daws (tsis kho).
304: Tsis muaj qhov pom corrosion tom qab 500 teev, nrog tsuas yog me ntsis saum npoo discoloration.
2. Acidic ib puag ncig ua tau zoo
| Nruab nrab | Kev xav ntsoov | Qho so | 301 lub sijhawm tsis ua hauj lwm | 304 lub sijhawm tsis ua hauj lwm |
|---|---|---|---|---|
| Sulfuric acid | 5% | Chav Temp | 120 teev | 300 teev |
| Nitric Acid | 20% | Haus | Tam sim ntawd corrosion | Tolerates 1 teev |
301 Stainless hlau thiab 304 Stainless Hlau: Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | 301 (anealed) | 304 (anealed) | 301 (ua haujlwm txias) |
|---|---|---|---|
| Paib lub zog | 215 MPa | 205 MPa | 520 MPa (+142%) |
| Lub zog tensile | 520 MPA | 515 MPa | 700 MPa |
| Elongation | 40% | 40% | 15% |
301 Stainless hlau thiab 304 Stainless hlau: Vuam Kev Ua Haujlwm
| Vuam txoj kev | 301 welding cov yam ntxwv | 304 vuam cov yam ntxwv |
|---|---|---|
| Tig Vuam | Tam sim no tsawg dua lossis sib npaug rau 120A kom tsis txhob muaj cov qoob loo grainening | ER308 Cov tub txuv pom zoo, cov lus tawm kub dua lossis sib npaug rau 15kj / cm |
| Laser Vuam | Weld hardness hv 250-300}}, nquag mus txias tawg | Weld hardness hv 200-250}, yuav tsum sib cav |
301 stainless hlau thiab 304 stainless hlau: nqi
1. Kev yuav khoom Them Nqi
301 daim ntawv nqi: ~$ 2.8 / lb(2025 Thoob Ntiaj Teb Hauv Ntiaj Teb).
304 daim nqi: ~$ 3.2 / lb, 14% hwm.
2. Txij Nkawm Kev Sib Tw (Thaj Chaw Nqaum)
301: Yuav tsum muaj xeb cov duab pov thawj xeb txhua 2 xyoos, 10-}} xyoo tswj nqi ~$ {0. 8 / lb.
304: No maintenance, lifespan >15 xyoos.
