Degree thiab txwv ntawm Hardness nce

 

Lub degree ntawm hardness nce los ntawm phosphorus segregation yog muaj feem xyuam rau cov ntsiab lus phosphorus thiab qib ntawm segregation. Feem ntau hais lus, qhov siab dua cov ntsiab lus phosphorus thiab qhov sib cais hnyav dua, qhov loj ntawm qhov hardness yuav ntau dua. Txawm li cas los xij, qhov kev nce hauv hardness yog txwv.

 

Vim tias phosphorus cais ua rau cov khoom nkig thaum nce hardness. Thaum raug rau lub zog sab nraud, cov khoom siv ncaj qha tuaj yeem muaj qhov tawg ntawm qhov tsis muaj zog ntxiv los ntawm cov yas deformation zoo li cov khoom siv tawv tawv. Yog li ntawd, hauv kev siv tswv yim, qhov kev nce hauv hardness coj los ntawm phosphorus cais yuav tsis muaj txiaj ntsig zoo, tshwj xeeb tshaj yog rau cov qauv welded uas yuav tsum tau muaj qee qhov kev sib tw thiab tawv tawv tib lub sijhawm.

 

 

 

 

 

 

BV / D460 steel phaj

BV D460 steel yog ib hom siab tensile zog marine steel. Tag nrho cov hlau no tau raug tsim los ua kom zoo tshaj plaws nyob rau hauv shipbuilding steels.BV D460 Shipbuilding steel daim hlau yog tsuas yog siv los ua cov offshore roj drilling platform, lub nkoj nkoj tsim thiab kho nkoj, platform yeeb nkab pob qij txha thiab lwm yam khoom.

 

 

Indirect Influence ntawm lub koom haum nrog lwm yam khoom hloov pauv ntawm Hardness

 

Qhov txo qis hauv toughness thiab ductility ntawm tshav kub - cuam tshuam cheeb tsam tshwm sim los ntawm phosphorus segregation kuj yuav cuam tshuam cov nyhuv ntawm hardness. Thaum lub toughness thiab ductility ntawm cov ntaub ntawv zuj zus lawm, thaum lub sij hawm ib tug hardness xeem los yog nyob rau hauv tiag tiag siv, cov khoom yuav muaj feem ntau muaj xws li cov kab nrib pleb.

 

Qhov tshwm sim ntawm cov kab nrib pleb no yuav ua rau cov txiaj ntsig ntawm qhov kev sim hardness tuaj yeem sib txawv vim qhov kev ntxhov siab nyob ib puag ncig cov kab nrib pleb yuav hloov qhov kev ntxhov siab tiag tiag ntawm cov khoom. Ntxiv mus, nyob rau hauv kev siv tiag tiag, ib zaug cov kab nrib pleb tshwm sim, cov khoom tiv thaiv rau deformation yuav txo qis vim kev puas tsuaj ntawm cov qauv kev ntseeg. Los ntawm qhov kev xav no, nws tseem yuav cuam tshuam rau kev ua haujlwm hardness ntawm cov khoom siv.
