09crCusb (ND Steel) Seamless Tus Hlau Tube

09crCusb (ND Steel) Seamless Tus Hlau Tubeis an alloy steel designed to resist low-temperature dew-point corrosion from sulfur-containing flue gases. Tus 09CrCusb (ND hlau) yog cov ntawv sau muaj los txheeb xyuas cov hlau tiv thaiv steel tiv taus kom tsis txhob muaj cov sulfuric acid. Nws yog feem ntau siv nyob rau hauv cov khoom siv xws li boiler tw neeg cua sov cua sov, hloov cua sov, thiab cov kav dej sov.
This material, a 09CrCuSb alloy steel, is specifically designed to resist sulfuric acid corrosion caused by condensation from sulfur-containing flue gases. Nws corrosion tsis kam muaj qhov tsis tshua zoo tib yam steel hlau, stainless hlau, thiab qee cov hlau txawv teb.

Cov Khoom Siv Ntawm 09CrCusb (ND Steel) Seamless Tus Hlau Tube

▔▔▔▔

Los ntawm kev sab laj cov ncauj lus kom ntxaws ntxaws thiab hais txog cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv corrosion thiab corrosion tsis kam ntawm cov lus saum toj no, cov lus xaus hauv qab no tuaj yeem kos:

 Tshuaj lom neeg cov tshuaj: GB / T 150.2-2011 (Siab Hlav Hlav Hlau Hlau), Kev Siv Tshuaj Txhuam Hlau), Cu 0.25%, thiab SB Tsawg dua 0.10%.

 Cov Khoom Siv Neeg Kho Tshuab: Tensile lub zog 390-550 MPa, tawm kom muaj zog dua los yog sib npaug nrog 25%, kev cuam tshuam nyuaj 50 j / cm² (-20 degree).

 Corrosion Kuj:

A.) Corrosion tus nqi tsawg dua los yog sib luag rau 14 mg / cmed he 50% h ₂₂₄ daws ntawm 70 degree. Kuj rau cov sulfuric acid dew point corrosion yog tshaj 10 zaug uas ntawm tib neeg cov hlau, surpassing stainless hlau thiab hlau hlau.

B.) Cov ntaub ntawv Chromium cov duab ntom ntom ntom xim los thaiv kev ua kom xeb, thaum tooj liab thiab cov neeg pleev tshuaj pleev ua kom zoo dua. Ultra - Cov ntsiab lus me me (tsawg dua lossis sib npaug nrog 0.10%) txo qhov kev pheej hmoo ntawm kev pheej hmoo ntawm corrosion intergranular.

Kev Siv ntawm 09crCusb (ND Steel) Seamless Tus Hlau Tube

Fais fab / boiler kev lag luam:Accialers Eceaters, thiab kev hloov cua sov hauv siab -}}} sulfur fluue gas ib puag ncig.

Petrochemical / Cov Khoom Siv Tshuaj:Sulfuric acid condensers, chav nyob uulfurization, thiab hydrofluoric acid rov qab cov khoom siv. Withstands 120℃concentrated sulfuric acid thiab complex media muaj so u₂ / hc.

Hloov siab - tus nqi siv:Tus nqi ua lag luam tsuas yog 40% ntawm 316L stainless hlau, thiab nkawm kev sib kis tau txuas los ntawm 2-3 zaug.
