Cov ntsiab lus carbon	Tsawg dua los yog sib npaug rau 0.03%	Tsawg dua los yog sib npaug rau 0.03%
Corrosion Kuj	Zoo tshaj	Zoo tshaj
Cov Khoom Siv Neeg Kho Tshuab	Me ntsis siab dua	Me ntsis qis dua vim yog cov qauv nrum
Cov Ntawv Thov	Tso Tsheb Hlau Luam, Pipelines, Sheet Hlau	Lub cev tso qoob loo, lub cuab yeej valve, tsis kam lees

 

Q1: yog 1.4409 tib yam li 1.4404?
Tsis yog, 1.4409 tsis yog tib yam li 1.4404. Ob qho tib si yog Austenitic stainless hlau, tab sis 1.4409 feem ntau muaj lub zog zoo dua li 1440) thiab ua kom muaj zog zoo dua li 1.440)

 

Q2: CF3M piv rau 316L yog dab tsi?
CF3M yog lub Attm casting qib sib npaug ntawm 316L, muab cov tshuaj tiv thaiv corrosion zoo heev.

 

Q3: Uas muaj cov tshuab ua kom zoo dua qub, 1.4404 lossis 1.4409?
1.4409 muaj kev siv tshuab ntau dua li 1.4404. Feem ntau, 1.440 muaj lub zog tensile ntawm 500-700 MPa thiab tau cog lus lub zog ntawm 53 MPa lossis siab dua, txhim kho nws txoj kev ntxhov siab.

 

Q4: Qhov twg yog 1.4409 (CF3M) siv feem ntau?
Nyob rau hauv lub cev lub cev, li qub, flanges, thiab cam khwb cia fittings uas muaj nyob rau hauv geometry yog xav tau.

 

Lub casting sib npaug ntawm 1.4404 stainless hlau (316L) yog 1.4409 / CF3m. Thaum ob tus menyuam kawm qib sib koom nrog kev sib xyaw ua ke thiab kev xaiv corrosion, kev xaiv yog yog nyob ntawm seb koj puas xav tau cov khoom siv / siv cov khoom siv lossis nrum seem.
Ntawm GNee, peb muab obli4404 stainless hlau daim hlau, kav dej, thiab cov coils, nrog rau 1.4409 casated rau li qub, twj, thiab kev cai fittings. Tiv tauj peb Hnub No kom tau txais cov lus sib tw ua rau koj lub phiaj xwm.Anail:sales@gneestainless.com
