LR Marine Steel Phaj Qib EH32

Lub nkoj tsim steel phaj Qib EH32 muaj cov yam ntxwv hauv qab no:
Hais txog tshuaj muaj pes tsawg leeg:

Cov ntsiab lus carbon tsawg: Cov ntsiab lus carbon (C) feem ntau tsawg dua lossis sib npaug rau 0.18%. Cov pa roj carbon tsawg pab txhim kho kev ua haujlwm ntawm cov hlau phaj thiab txo qhov muaj peev xwm ntawm cov kab nrib pleb thiab lwm yam tsis xws luag thaum vuam, ua rau cov phaj hlau yooj yim rau welded thaum lub nkoj tsim.

Tus nqi tsim nyog ntawm manganese: Cov ntsiab lus ntawm manganese (Mn) yog nyob nruab nrab ntawm {{0}}.90 - 1.60%. Manganese caij tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau phaj thiab txhim kho lub peev xwm ntawm cov phaj hlau los tiv thaiv sab nrauv thiab deformation. Nws yog ib qho tseem ceeb heev rau cov nkoj kom tiv taus ntau yam kev ntxhov siab thiab kev cuam tshuam nyob rau hauv ib puag ncig marine.Control ntawm lwm cov ntsiab lus: Cov ntsiab lus ntawm silicon (Si) nyob nruab nrab ntawm 0.10 - 0.50% , cov ntsiab lus ntawm phosphorus (P) tsawg dua lossis sib npaug li 0.04%, thiab cov ntsiab lus ntawm sulfur (S) tsawg dua lossis sib npaug li 0.04%. Kev tswj xyuas nruj ntawm cov ntsiab lus no pab ua kom lub siab huv thiab zoo ruaj khov ntawm cov phaj steel thiab txo cov kev tsis zoo ntawm cov khoom tsis zoo ntawm kev ua haujlwm ntawm cov phaj steel. Cov ntsiab lus ntawm txhuas (Al) yog ntau dua lossis sib npaug li 0.015%. Cov khoom siv txhuas hauv cov hlau tuaj yeem ua lub luag haujlwm hauv kev ua kom zoo cov nplej, txhim kho toughness thiab oxidation kuj.

 

 

 

Nyob rau hauv cov nqe lus ntawm mechanical zog:

Lub zog siab: Lub zog tawm los yog ntau dua lossis sib npaug rau 315MPa, thiab lub zog tensile nyob nruab nrab ntawm 440 - 570MPa. Qhov no kuj muaj zog muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm cov qauv nkoj rau cov khoom siv thauj khoom, ua rau cov nkoj tuaj yeem tiv taus ntau yam kev thauj khoom thaum taug kev, suav nrog qhov hnyav ntawm lub nkoj nws tus kheej, qhov hnyav ntawm cov khoom thauj, qhov siab ntawm seawater, thiab kev ua haujlwm. ntawm sab nraud zog xws li cua thiab nthwv dej.

Zoo toughness: Nws muaj qhov toughness zoo, tshwj xeeb tshaj yog tswj xyuas qhov zoo ntawm qhov toughness ntawm qhov kub thiab txias. Piv txwv li, hauv qee cov qauv, nws yuav tsum tau ua kom lub zog ntawm cov phaj steel nce mus txog ib qho nqi nyob rau hauv ib qho chaw qis qis (xws li -40 degree ). Cov tawv tawv zoo tuaj yeem ua rau cov phaj hlau tsis tshua muaj kev tawg thaum raug cuam tshuam los yog thauj khoom sai, txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov nkoj.

Zoo ductility: Tus elongation tus nqi ntau dua los yog sib npaug li 21% (tsawg kawg), qhia tias cov hlau phaj muaj cov yas zoo thiab ductility thiab tuaj yeem tiv taus qee qhov deformation thaum ua thiab siv yam tsis muaj kev tawg yooj yim.

LR yog hais txog Lloyd's Register Group Limited, lub koom haum UK siab rau kev tshawb fawb thiab kev kawm hauv science thiab engineering.
