Dab tsi yog qhov txawv ntawm 1.4315 thiab 1.4301 stainless hlau?

Ob leeg 1.4301 thiab 1.4315 yog austenitic stainless hlau nrog cov ntsiab lus zoo sib xws (muaj 18-19% chromium thiab 8-10% nickel); Txawm li cas los xij, qhov sib txawv ntawm ob yog tias 1.4315 (X5CrNiN19-9) tau dhau los ntawm nitrogen alloying, ua rau muaj zog dua piv rau tus qauv 1.4301 (X5CrNi18-10, piv txwv li, AISI 304).

 

Dab tsi yog qhov txawv ntawm 1.4315 thiab 1.4307 stainless hlau?

Ob leeg EN 1.4307 (304L) thiab 1.4315 (X5CrNiN19-9) yog austenitic stainless hlau; tshwj xeeb, 1.4315 nthuav tawm lub zog ntau dua vim qhov sib ntxiv ntawm nitrogen ua cov khoom siv alloying, whereas 1.4307 (cov pa roj carbon tsawg) yog qhov zoo dua rau kev vuam . 1.4307 qhia tau zoo heev corrosion kuj thiab tshwj xeeb tshaj yog haum rau welded Cheebtsam; Hauv qhov sib piv, 1.4315 feem ntau yog xaiv thaum lub zog ntawm cov qauv kev xav tau ntau dua.

 

1.4315 Stainless Hlau: Corrosion Resistance

1.4315 (X5CrNiN19-9) yog austenitic stainless hlau nrog zoo corrosion kuj, superior rau qib 302 vim nws cov nitrogen-alloyed muaj pes tsawg leeg. Nws muaj kev ua haujlwm zoo hauv oxidizing ib puag ncig, siab tensile zog, thiab zoo weldability. Nws yog dav siv rau fasteners nyob rau hauv me me corrosive ib puag ncig.

1.4315 Stainless hlau: Machinability

1.4315 (X5CrNiN19-9) yog ib qho austenitic stainless hlau nrog nruab nrab machinability, feem ntau zoo ib yam li los yog me ntsis nyuaj rau lub tshuab dua Qib 304 vim siab nickel thiab nitrogen cov ntsiab lus, uas ua rau kom toughness thiab ua hauj lwm hardening. Nws nquag siv rau forged, siab - lub zog qhov chaw es tsis siv lub tshuab ua haujlwm siab ceev.

Puas yog 1.4315 stainless hlau sib nqus?

1.4315 (X5CrNiN19-9) yog ib qho austenitic stainless hlau uas feem ntau tsis sib nqus hauv nws lub xeev annealed. Txawm li cas los xij, vim nws muaj pes tsawg leeg, nws tuaj yeem tsim cov khoom sib nqus me ntsis thaum raug ua haujlwm txias, xws li khoov, dov, lossis kos duab.
