254 Smo Tube Corrosion Resistance

SS254SMO yeeb nkab nthuav tawm zoo heev corrosion kuj nyob rau hauv siab chloride ion thiab acidic media. Nws tuaj yeem tiv taus dej hiav txwv, aeration, crevice corrosion, thiab qis -ceev yaig ib puag ncig, qhia tau zoo heev rau pitting thiab crevice corrosion (PI Ntau dua los yog sib npaug rau 40). Nws kuj qhia tau hais tias muaj zog tiv thaiv ob qho tib si txo thiab oxidizing acids xws li sulfuric acid, phosphoric acid, thiab acetic acid.

Qhov qis carbon thiab siab nitrogen tsim tshem tawm cov kev pheej hmoo ntawm intergranular corrosion ntawm kub kub los yog tom qab vuam. Nws tuav lub xeev passive ruaj khov txawm tias nyob rau hauv 15% siab -concentration chloride ion acidic tov (pH=1.5, 40 degree), nrog rau passive tam sim no ceev ntawm tsuas yog 0.022 mA / cm², deb superior rau 2205 duplex stainless hlau.

aisi a312 yeeb nkab s31254 Mechanical Properties

Tensile zog: 650-850 MPa, yield zog: 300-340 MPa, elongation: Ntau tshaj los yog sib npaug rau 35%. Nws tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm nyuaj xws li kev kub siab thiab qhov kub thiab txias, tsis muaj kev txhawj xeeb txog kev ua haujlwm tsis zoo vim tsis txaus toughness.

uns s31254 steel yeeb nkab Ua thiab Vuam Performance

Rau kev ua haujlwm txias, nws tuaj yeem tsim siv cov txheej txheem xws li ncab, khoov, flaring, thiab flanging. Txawm hais tias nws lub zog siab dua 316L, ua rau muaj kev ua haujlwm nyuaj me ntsis, nws tseem tuaj yeem ua tau raws li kev tsim khoom ntawm cov txheej txheem nyuaj.

Vuam tuaj yeem ua tau los ntawm kev siv cov txheej txheem xws li TIG, MIG, thiab laser vuam . 6mo yeeb nkab tau pom zoo kom siv ERNiCrMo-3 high-nickel alloy muab tub lim. Tsis muaj kev kho cua sov tshwj xeeb yog xav tau tom qab vuam kom muaj kev tiv thaiv corrosion.

Kev ua haujlwm kub yuav tsum tau ua nyob rau hauv qhov kub ntawm 950-1150 degree, ua raws li cov cua txias kom ua tau zoo.

super stainless hlau 254 smo Siab -Tub kub tsis kam

6mo yeeb nkab tuaj yeem siv rau lub sijhawm luv luv hauv oxidizing ib puag ncig ntawm 120 degree. Qhov pom zoo ntev -lub sijhawm ua haujlwm kub yuav tsum tsis pub tshaj 600℃. Cov ntsiab lus siab chromium thiab npib tsib xee ua kom oxidation tsis kam thiab thermal stability ntawm qhov kub thiab txias, ua rau nws haum rau siab -kub siv xws li flue gas desulfurization thiab nuclear fais fab nroj tsuag.
