416 vs 420f Stainless Hlau: Martensitic Dawb- kev siv machining

 

Lawv cov khoom sib txawv li cas?

416 muaj 12 {{{{- 14% chromium, 0,5-0% carrium, thiab xaiv cov pa roj carromerg, thiab xaiv cov pa roj carbon monoxent, nrog cov pa roj carbon monoxide, thiab xaiv tau cov pa roj carromerg, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv tau cov pa roj carromenum, thiab xaiv cov pa roj ntau dua cov hardness.

 

Qhov twg muaj cov hardness zoo dua thiab hnav tsis kam?

420F ncav cuag 50 {{6- 55 hrc tom qab kev kho cua sov, nyuaj tshaj 416 40-45 HRC. Qhov no ua rau 420f ntau cov kev hnav-tiv taus, haum rau kev cov cuab yeej, thaum 416 sib npaug congerinity nrog lub zog muaj zog.

 

Yuav ua li cas lawv sib piv hauv corrosion tsis kam?

Ob qho tib si muab me me corrosion tsis kam nyob rau hauv cov chaw qhuav, nrog 420f me ntsis outperforming 416 vim muaj cov chromium ntau dua. Lawv tuaj yeem xeb hauv noo noo lossis qab ntsev, xav tau kev tiv thaiv hauv kev ua haujlwm hnyav.

 

Yuav ua li cas hais txog lawv machining thiab kev siv hluav taws xob?

416 tau yooj yim me ntsis rau lub tshuab tshaj 420f, nrog Sulphur txhim kho nti Flow {2} fe zoo dua kev kho mob tom qab kev kho cua sov, ua rau nws zoo dua rau qhov chaw precision.

 

416 thiab 420f feem ntau siv?

416 yog nyob rau hauv valve stoms, zog, thiab fasteners {1} f nrhiav tau cov kev siv uas tau siv cov tshuab uas xav tau zoo machinability thiab hardness.
