Yog 1.4408 sib npaug rau SS316?

Dab tsi yog sib npaug rau 316 stainless hlau?

Cov hlwv muaj feem ntau rau 316 stainless hlau yog European / Metric Stand A4 lossis ENTUM A4 lossis ENTROLE UNLOCONS UNSOM UNCUS UNCRESS UNCTENS UNR31600. Koj kuj tseem tuaj yeem pom 316 raug xa mus rau los ntawm nws cov yam ntxwv, xws li Marine qib stainless, lossis qis} roj carbon version, 316L (tsis muaj S31104).

 

Cov khoom siv twg yog sib npaug rau 1.4408?
Yog lawm, European txheem stainless hlau en 1.4408 (tseem hu ua Gxäcnimo19-11-2) Zoo ib yam li ANTONS14A nyob rau hauv nws cov khoom thiab cov khoom. Nws yog ib tug cam khwb cia stainless hlau siv rau nws corrosion tsis kam thiab muaj feem ntau pom nyob rau hauv kev lag luam xws li roj thiab roj.

 

Yog 1.4408 sib npaug rau SS316?

Yog, en 1.4408 yog qhov cam me me stainless uas yog sib npaug ntawm American casting qib CF8M, thiab yog suav hais tias yog cov cam cast version ntawm SS316. Thaum ob qho tib si sib faib cov tshuaj sib thooj zoo sib xws, lawv cov kev tsim kho kom pom tias lawv siv: 1.4408 (lossis AISSAS 316) yog rau cov khoom lag luam zoo li cov phaj zoo li cov ntawv, thiab cov ntawv tuav.

Weldability:

1.4401 muaj kev siv weldability zoo dua rau 1.4408, ua rau nws tsim cov khoom siv vuam ntxiv, nws yuav tsum tau kho cov khoom siv cua sov kom tiv thaiv cov teeb meem zoo li cov teeb meem zoo li lub siab.

 

Qhov sib txawv tseem ceeb hauv cov ntawv thov
Casting vs. Fabrication:
1.4408 feem ntau yog siv nyob rau hauv Casting daim ntawv thov. Nws yog qhov zoo tagnrho rau kev tsim cov khoom lag luam xws li qub, nqus cov twj, thiab cov khoom siv nyuaj siab uas xav tau lub zog siab thiab corrosion tsis kam nyob rau hauv cov ntawv cam.
1.4401 tau siv dav hauv welded thiab fabricated daim ntawv thov, suav nrog cov kav dej, tso tsheb hlau luam, thiab lwm yam khoom siv kev lag luam uas xav tau cov txheej txheem vuam.
