SS DIN 1.4550 Cold Rolled Coiled Tubes
1.4550 steel yeeb nkabyog niobium-stabilized austenitic stainless hlau. Niobium ntxiv los txhim kho intergranular corrosion kuj. Nws cov corrosion kuj nyob rau hauv corrosive media xws li acids, alkalis, thiab ntsev yog tib yam li 321 stainless hlau kav. Nws muaj kev ua haujlwm vuam zoo thiab tuaj yeem siv los ua cov ntaub ntawv tiv thaiv thiab siv cov hlau kub-resistant. Qhov chaw nyob rau hauv corrosion tej yam kev mob ntawm 400 ~ 900 degrees, kub kub vuam yam ntxwv qhov chaw.
oxidation tsis kam, creep kuj thiab qaug zog tsis kam ntawm 1.4550 Stainless Steel Thick Wall Pipe nyob rau hauv qhov chaw kub kub nyob ntawm nws cov alloy muaj pes tsawg leeg thiab microstructure. Cov tshuaj muaj pes tsawg leeg ntawm 1.455{{10}} yog: C: Tsawg dua lossis sib npaug rau 0.05, Si: Tsawg dua lossis sib npaug rau 1.00, Mn: Tsawg dua lossis sib npaug rau 1.00, P: Tsawg dua lossis sib npaug rau 0.040, S: Tsawg dua lossis sib npaug rau 0.030, Cr: 16.00-19.00, Ni: 9 .00-11.00, Mo: 0.80-1.50. Nyob rau hauv cov txheej txheem xws li laser txiav thiab vuam, lub siab melting point thiab zoo thermal stability ntawm 1.4550 pab txhim kho kev ua tau zoo thiab txo cov nqi ntau lawm.
Kev kho polishing ntawm 1.4550 Stainless Hlau Polished Yeeb Nkab tuaj yeem txhim kho nws qhov chaw tiav, txo cov adhesion ntawm cov pa phem, thiab txhim kho kev tu cev. Mechanical zog ntawm 1.4550: tensile zog 650 MPa, yield zog 300 MPa, elongation 35%. 1.4550 muaj hluav taws xob tiv thaiv kev ua haujlwm siab hauv kev lag luam nuclear xws li nuclear reactors thiab radioactive pov tseg.
Hauv cov ntsiab lus, 1.4550SS High Pressure Pipe ua lub luag haujlwm tseem ceeb hauv kev tsim kho thiab kev tsim kho vaj tse, thiab kev tiv thaiv corrosion ntawm 1.4550 tuaj yeem txhim kho ntxiv los ntawm kev tsim cov hlau alloy thiab kev kho deg.
