Dab tsi yog qhov sib txawv ntawm 1.4841 thiab 1.4845 stainless hlau?

Puas yog koj tab tom nrhiav rau cov hlau tsis muaj zog rau cov ntawv thov kub? Qib 1.4841 (AISI 310) thiab 1.4845 (AISI 310s) yog cov kev xaiv zoo ua tsaug rau lawv cov oxidation zoo heev thiab thermal ruaj khov. Txawm hais tias ob qho tib si yog cov tsev neeg ntawm anustenitic stainless hlau nrog cov chromium siab (ni) cov ntsiab lus sib txawv, cov cuab yeej siv neeg kho mob thiab cov ntawv thov tshwj xeeb.

Hauv qab no, peb nthuav qhia txhua yam koj yuav tsum paub xaiv cov khoom siv tau, nrog rau GNEE Stainless cov kev muab tshwj xeeb.

Qhov sib txawv ntawm 1.4841 thiab 1.4845

1. Tshuaj lom neeg: Lub luag haujlwm ntawm carbon

Ob qib kawm muaj cov chromium siab (24-26%) thiab npib tsib xee (19-22%) cov ntsiab lus, muab lawv oxidation zoo heev thiab kev ruaj ntseg nyob rau hauv thermal ib puag ncig. Lub ntsiab txawv yog nyob hauv cov pa roj carbon (c):

Caij (%)	1.4841 (AISI 310)	1.4845 (AISI 310s)
Carbon (c)	Tsawg dua los yog sib npaug rau 0.20%	Tsawg dua los yog sib npaug rau 0.08% (tsawg dua)
