Dab tsi yog qhov sib txawv ntawm 1.440 thiab 1.4541 stainless hlau?
Thaum xaiv cov hlau tsis xeb rau kev siv tshuaj, tshwj xeeb tshaj yog hauv cov kev siv tshuaj, lossis cov qib nrov ntau zaus tuaj rau hauv cov qib: EN 1.440 (AISI 316) (AISI 321). Ob qho tib si yog Austenitic stainless hlau, tab sis lawv ua lub hom phiaj sib txawv raws li lawv cov tshuaj lom neeg muaj kuab lom, corrosion tsis kam, thiab kub siab ntev.
1.4404 Stainless Hlau AISI 316L Kev Tshuaj Ntsuam
1.4404 stainless hlau (AISI 316L \/ X2CNNO {{})
Tshuaj lom neeg cov tshuaj:Muaj 17% cr, 12% ni, thiab 2-2.5% mo
Cov ntsiab lus carbon:Ultra-Low (tsawg dua los yog sib npaug rau 0. 03%), minimizing carbide nag
Corrosion Kuj:Zoo heev rau chloride-ntxias pitting thiab crevice corrosion
Weldability:Tshwj xeeb, tsis muaj kev pheej hmoo ntawm intergranular corrosion-vuam
Cov Ntawv Thov:Qhov zoo tshaj plaws rau Marine-Qeb Stainless hlau Cheebtsam, kev lag luam tshuaj lom neeg, thiab huv si
Qauv:ASTM A240, en 10088-2}, unsist S31603
1.4541 Stainless hlau (AISI 321 \/ x6cniti 18-10)
Tshuaj lom neeg cov tshuaj:Zoo ib yam li 304 stainless hlau nrog titanium (ti) ntxiv rau kev ruaj khov
Cov ntsiab lus carbon:Mus txog 0. 08%, tab sis stabilized nrog ti los tiv thaiv chomium carbide tsim
Kub-Kub Kuj:Zoo dua li 1.4404; Tsis kam cuam tshuam corrosular nyob rau hauv 600-850 degree ntau yam
Weldability:Zoo; Ti pab tiv thaiv tiv thaiv kom muaj weld lwj
Cov Ntawv Thov:Feem ntau siv rau hauv kev nqus tshuab, kev sib pauv cua sov, thiab cua sov rwb thaiv tsev tsho khuam
Tus qauv: ASTM A240, thiab 10088-2}}, uns s32100
