Carbon sib npaug thiab Crack Sensitivity

LR AH46 steel daim hlau muaj qhov zoo tswj cov pa roj carbon sib npaug (CE) thiab tawg rhiab heev. Cov pa roj carbon sib npaug yog qhov ntsuas tseem ceeb rau kev ntsuas qhov weldability. Feem ntau, cov pa roj carbon sib npaug ntawm LR AH46 steel yog tsim los nyob rau hauv ntau yam uas tso cai rau kev vuam zoo. Piv txwv li, nws yog feem ntau nyob ib ncig ntawm 0.4 - 0.45, uas yog piv rau lwm cov high-lub zog shipbuilding steels.

Hauv kev sib piv rau qee qhov qis dua - lub zog shipbuilding steels zoo li A - qib thiab B - qib steels, cov pa roj carbon sib npaug ntawm LR AH46 steel yog me ntsis siab dua vim nws cov kev xav tau siab dua. Txawm li cas los xij, piv rau qee qhov ultra - siab - lub zog lossis tshwj xeeb - alloyed steels, nws muaj txiaj ntsig zoo dua cov pa roj carbon sib npaug uas ua rau nws tsis tshua muaj qhov txias txias thaum vuam.

Vuam txoj kev Compatibility

LR AH46 steel yog sib xws nrog ntau yam vuam txoj kev uas feem ntau siv hauv nkoj tsim. Cov no suav nrog phau ntawv arc vuam, submerged arc vuam, thiab roj-shielded arc vuam.

Piv txwv li, nyob rau hauv phau ntawv arc vuam, nws muaj peev xwm tsim ib tug ruaj khov vuam arc thiab tsim zoo - zoo welds. Lub vuam hlau thiab flux siv rau submerged arc vuam tuaj yeem raug xaiv raws li cov kev cai tshwj xeeb ntawm LR AH46 steel kom ntseeg tau tias kev nkag mus tau zoo thiab fusion. Nyob rau hauv cov roj - shielded arc vuam, cov roj shielding tuaj yeem tiv thaiv lub pas dej ua ke thiab txo cov oxidation ntawm cov hlau molten, uas ua rau muaj qhov zoo ntawm vuam.

Piv rau qee qhov tshwj xeeb - alloyed steels uas yuav tsum tau ua ntej cua sov los yog tom qab - vuam kev kho cua sov kom ntseeg tau tias weldability, LR AH46 steel tuaj yeem welded nyob rau hauv ib txwm vuam tej yam kev mob nyob rau hauv ntau zaus. Txawm li cas los xij, rau tuab - ntu LR AH46 steel daim hlau, qhov tsim nyog ua ntej cua sov kuj tseem yuav tsim nyog los txo qhov kev pheej hmoo ntawm kev tawg.

Weld Quality thiab Mechanical Properties of Weld Joints

Lub vuam zoo ntawm LR AH46 steel daim hlau feem ntau yog siab. Lub microstructure ntawm vuam thiab tshav kub - cuam tshuam cheeb tsam tuaj yeem ua tau zoo - tswj los ntawm cov txheej txheem vuam kom raug. Cov cuab yeej cuab tam ntawm cov pob qij txha, xws li lub zog tensile, cuam tshuam toughness, thiab hardness, yog ze rau cov hlau puag.

Piv txwv li, lub zog tensile ntawm qhov sib koom ua ke tuaj yeem ncav cuag qhov siab (feem ntau ntau dua 90%) ntawm lub zog tensile ntawm lub hauv paus hlau. Qhov cuam tshuam toughness ntawm weld thiab tshav kub - cuam tshuam cheeb tsam kuj tseem khaws cia nyob rau hauv ib theem uas ua tau raws li cov kev cai ntawm shipbuilding qauv, kom ntseeg tau tias cov welded qauv muaj peev xwm tiv taus qhov cuam tshuam loads thaum lub sij hawm lub nkoj ua hauj lwm.

 

 

 

 

 

 

 

 

 

Corrosion Resistance ntawm Welds

Cov welds ntawm LR AH46 steel daim hlau muaj qhov zoo corrosion kuj. Cov ntsiab lus alloying nyob rau hauv cov hlau thiab cov txheej txheem vuam zoo pab kom ntseeg tau tias cov welds muaj qhov zoo sib xws rau cov hlau hauv lub hauv paus hauv marine ib puag ncig.

Piv txwv li, hauv dej hiav txwv, cov welds ntawm LR AH46 steel tsis tshua muaj kev txom nyem los ntawm pitting corrosion thiab crevice corrosion piv rau qee cov hlau uas tsis zoo weld - corrosion kuj. Kev tsim cov yeeb yaj kiab ruaj khov rau ntawm qhov chaw vuam vim yog cov khoom sib txuas thiab cov txheej txheem vuam kom zoo pab tiv thaiv cov welds los ntawm corrosive kev txiav txim ntawm seawater thiab lwm yam corrosive media nyob rau hauv shipbuilding ib puag ncig.

Hauv kev sib piv rau qee cov hlau uas yuav xav tau kev txhim kho corrosion ntxiv - kev tiv thaiv kev ntsuas rau welds, LR AH46 steel muab kev tiv thaiv zoo dua qub rau welds, txo qhov nyuaj thiab tus nqi ntawm corrosion - kev tiv thaiv rau cov qauv welded.
