Kev piav txog

420 stainless hlau hlau hlau, tseem hu ua Sus420J2 lossis PC15, yog tus sawv cev Quintessential ntawm Martensitic Stainless hlau. Nws ua tiav qhov sib npaug ntawm hardness thiab corrosion tsis kam los ntawm nws cov ntsiab lus carbon ntau (0.16% -0.40%) thiab cov ntsiab lus chromium (12% -14%). Nws cov khoom lag luam encompass hlau qws, cov hlau caij nplooj ntoo hlav, thiab cov cuab yeej siv kho mob, thiab kev lag luam hnav {{tsis kam ua ke.

ALLOY meej

Cov Khoom Siv Neeg Kho Tshuab

Hardness:Analed xeev tsawg dua los yog sib npaug rau 223 HB; Quenched thiab tempered lub xeev ncav cuag 50-55 hrc (ntau tshaj li 60 teev txog 60 teev)
Lub zog:Tensile lub zog ntau dua los yog sib npaug rau 635 MPA (nce 800-1000 MPa tom qab quenching)
Elongation:Annealed xeev ntau dua los yog sib npaug rau 20%; Quenched xeev ntau dua los yog sib npaug rau 10%

Corrosion Kuj

Tsim nyog ib puag ncig:Atmospherhers mob, dej tshiab, qaug zog acids / alkalis (piv txwv li, hws, xab npus, xab npum)
Txwv:Tsis txhob tiv taus ntsev dej, seasater, lossis cov xov xwm corrosive (piv txwv li, chloride {} ion ion ib puag ncig). Kev kho mob passivation yog yuav tsum tau txhim kho corrosion tsis kam.

Applrication

Cov Khoom Siv Kho Mob

Piv txwv:Kev Ntsuas Cov Cuab Yeej, Cov Cuab Yeej Kho Hniav
Qhov Zoo:Sib nqus tau sib nqus nrog cov txheej txheem kom tsis muaj menyuam; biocompatibility zoo heev tom qab polishing

Kev Coj Nqis Hnav
