Bambance-bambance Tsakanin 316L da 304 Bakin Karfe

Duka316 da 304ne austenitic bakin karfe da aka yi amfani da ko'ina a masana'antu, gini, likita, da kuma abinci da alaka aikace-aikace. Koyaya, sun bambanta sosai a cikinsinadaran abun da ke ciki, lalata juriya, inji Properties, da kuma aikace-aikace.

1. Sinadarin Haɗin Kai

304 Bakin Karfe: Da farko ya ƙunshi18% chromium (Cr) da 8% nickel (Ni), wanda shine dalilin da ya sa kuma aka sani da18-8 bakin karfe.

316L Bakin Karfe: Ya ƙunshi16-18% chromium, 10-14% nickel, da ƙari2-3% molybdenum (Mo), wanda ke inganta juriya na lalata.

The"L" a cikin 316Lyana tsaye donlow carbon (≤0.03%), inganta weldability da kuma rage hadarin intergranular lalata.

2. Juriya na Lalata

304 yana da juriya mai kyau na lalata, dace da yanayi na gabaɗaya da fallasa ga acid oxidizing.

316L yana ba da juriya na lalata, musamman a cikinwurare masu wadatar chloride(kamar ruwan teku da yanayin gishiri), godiya ga molybdenum, wanda ke taimakawa wajen tsayayyapitting da crevice lalata.

3. Kayayyakin Injini & Ƙarfafa Aiki

304 ya fi karfi, tare da matsakaicin taurin, yana sauƙaƙa aikin sanyi, lanƙwasa, da walƙiya.

316L ya ɗan rage ƙarfi amma ya fi ductile, tare da ƙananan abun ciki na carbon wanda ke ingantaweldability, Yin shi manufa don aikace-aikace inda bayan-weld magani zafi ba zai yiwu ba.

4. Kwatancen Kuɗi

316L ya fi 304 tsada, yafi saboda girman nickel da molybdenum, wanda ke ƙara yawan farashin samarwa.

5. Key Applications

Kammalawa

Idan aikace-aikacenku yana cikin ayanayi na gaba ɗaya(kamar kayan girki, kayan gini, ko kayan gida),304 zaɓi ne mai tsada. Duk da haka, donyanayi mai lalata sosai(kamar ruwan teku, sarrafa sinadarai, ko magunguna) koinda ake buƙatar ingantaccen weldability, 316L shine mafi kyawun zaɓi.
