Taw qhia
Stainless hlau yog cov khoom siv dav siv hauv ntau qhov kev lag luam vim nws cov khoom zoo heev, xws li corrosion kuj, durability, thiab lub zog. Ib hom stainless hlau uas feem ntau siv yog 304 stainless hlau, uas yog austenitic stainless hlau uas muaj chromium thiab npib tsib xee.
Hauv tsab xov xwm no, peb yuav tham txog tus qauv rau 304 stainless hlau phaj, suav nrog nws cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev siv.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm 304 stainless hlau phaj yog raws li nram no:
- Cov pa roj carbon (C): 0.08%
- Chromium (Cr): 18%
Nickel (Ni): 8%
- Manganese (Mn): 2%
Silicon (Si): 1%
- Phosphorus (P): 0.045%
- Sulfur (S): 0.03%
304 stainless hlau phajyog qhov sib txawv ntawm cov pa roj carbon tsawg ntawm 304 stainless hlau, uas txhais tau tias nws muaj cov ntsiab lus carbon tsawg dua li tus qauv 304 stainless hlau. Cov ntsiab lus carbon tsawg ua rau 304 stainless hlau phaj tsis tshua muaj kev nkag siab (ib daim ntawv ntawm corrosion) thiab muab kev sib txuas zoo dua.
Mechanical Properties
304 stainless hlau phajmuaj cov khoom siv kho tshuab zoo heev, uas ua rau nws haum rau ntau yam kev siv. Mechanical Properties ntawms30400 stainless hlau phajyog raws li nram no:
Qhov ceev: 8g / cm3
Elastic modulus: 193 GPa
- Tawm lub zog: 205 MPa
- Tensile zog: 515 MPa
- Elongation: 40%
- Hardness, Brinell: 201
Lub zog tensile siab thiab tsis tshua muaj zog ntawm 304 stainless hlau phaj ua rau nws cov khoom zoo tagnrho rau cov ntawv thov uas xav tau lub zog siab thiab tawv. Lub siab elongation ntawm 304 stainless hlau phaj kuj ua rau nws cov khoom zoo rau kev sib sau thiab shaping.
Daim ntawv thov
ASTM A 240 304 stainless hlau phajyog cov khoom siv ntau yam uas siv rau hauv ntau yam lag luam, xws li:
- Khoom noj khoom haus thiab dej haus kev lag luam: 304 stainless hlau phaj yog siv los ua khoom noj khoom haus, xws li cia tank, piping, thiab machinery qhov chaw.
- Kev lag luam tshuaj:AISI 304 stainless hlau phajyog siv los ua cov khoom siv tshuaj, xws li reactors, heat exchangers, thiab tanks.
- Kev lag luam kho mob:Alloy 304 stainless hlau phajyog siv los ua cov cuab yeej phais, kho mob cog, thiab cov cuab yeej kuaj mob.
- Automotive kev lag luam: 304 stainless hlau phaj yog siv los ua cov tshuab tso pa, mufflers, thiab lwm yam uas yuav tsum tau muaj kev tiv thaiv corrosion thiab kub ua hauj.
- Kev tsim kho kev lag luam: 1.4301 stainless hlau phaj yog siv los ua lub tsev facades, vov tsev, thiab cov khoom siv uas yuav tsum tau ua kom muaj zog thiab tiv thaiv corrosion.
