Kev kho Alloying

 

Ntxiv Alloying Elements: Thaum lub sij hawm cov hlau - ua cov txheej txheem, alloying ntsiab xws li chromium (Cr), npib tsib xee (Ni), thiab molybdenum (Mo) tuaj yeem muab ntxiv los txhim kho corrosion kuj ntawm LR DH55 steel daim hlau. Cov khoom siv chromium tuaj yeem tsim cov duab ntom ntom chromium oxide tiv thaiv rau ntawm cov phaj hlau. Cov yeeb yaj kiab no tuaj yeem tiv thaiv corrosive media xws li oxygen thiab noo noo los ntawm kev sib cuag nrog lub hauv paus hlau, yog li txhim kho corrosion kuj. Nickel tuaj yeem txhim kho qhov toughness thiab corrosion kuj ntawm steel, tshwj xeeb tshaj yog nyob rau hauv ib co corrosive ib puag ncig uas muaj chloride ions. Nickel tuaj yeem txo qhov cuam tshuam rau pitting thiab crevice corrosion. Cov khoom molybdenum tuaj yeem ntxiv dag zog rau cov hlau tsis kam rau pitting hauv chloride - muaj ib puag ncig thiab txhim kho nws cov kev tiv thaiv hauv zos corrosion.

 

Tswj cov ntsiab lus impurity: Cov ntsiab lus ntawm impurity ntsiab nyob rau hauv steel, xws li sulfur (S) thiab phosphorus (P), yuav tsum nruj me ntsis tswj. Sulfur thiab phosphorus yuav sib cais ntawm cov ciam teb, txo qhov toughness thiab corrosion kuj ntawm cov hlau. Los ntawm kev txo cov ntsiab lus ntawm cov impurity ntsiab los ntawm cov txheej txheem refining, qhov zoo thiab corrosion kuj ntawm LR DH55 steel daim hlau tuaj yeem txhim kho.

 

Txhim kho Environmental Conditions

 

Tswj cov av noo thiab kub: Yog tias ua tau, tswj cov av noo thiab qhov kub thiab txias ntawm qhov chaw nyob qhov twg LR DH55 steel phaj nyob. Txo cov av noo ib puag ncig tuaj yeem txo qhov hws ntawm cov av noo ntawm cov hlau phaj, vim tias cov av noo yog ib qho tseem ceeb uas ua rau corrosion. Rau qee qhov chaw sab hauv tsev uas LR DH55 steel daim hlau khaws cia lossis siv, lub tshuab dehumidifier tuaj yeem siv los tswj cov av qis. Nyob rau hauv cov nqe lus ntawm qhov kub thiab txias, tsis txhob muab cov hlau phaj nyob rau hauv ib puag ncig nrog ib tug ntse kub hloov, vim hais tias thermal kev nyuaj siab yuav ua rau lub txheej los yog tiv thaiv zaj duab xis kom tawg, yog li accelerating corrosion.

 

Isolating Corrosive Media: Yog tias cov ntawv hlau siv los sib cuag nrog cov kua dej tshwj xeeb lossis cov pa roj carbon monoxide, kev ntsuas kev sib cais tuaj yeem raug saws. Piv txwv li, corrosion - resistant yas zaj duab xis, roj hmab hauv ob sab phlu thiab lwm yam ntaub ntawv yuav siv tau los cais cov hlau daim hlau los ntawm corrosive media. Hauv cov khoom siv tshuaj, rau LR DH55 steel phaj ntim uas tuav cov kev daws teeb meem corrosive, cov khoom siv tiv thaiv corrosion xws li polytetrafluoroethylene tuaj yeem ua kab hauv qab kom tiv thaiv cov tshuaj los ntawm kev sib cuag ncaj qha nrog cov hlau phaj, yog li txhim kho corrosion kuj.
