CSFH460 yog lub nkoj ultra-high-strength steel phaj ntawv pov thawj los ntawm Tuam Tshoj Classification Society. Nws yog cov qauv hlau rau nkoj thiab dej hiav txwv engineering. F yog qib zoo, H yog cov khoom siv hauv tsev siab, thiab 460 yog lub zog qis zog. Hlau daim hlau nrog Z-kev taw qhia yuav tsum muaj cov lus tom qab Z25 lossis Z35 ntxiv, thiab siv los ua ultra-high-strength steel qauv rau nkoj thiab dej hiav txwv engineering.
CSFH460 kev kho cua sov txheej xwm: Cov hlau phaj yog nyob rau hauv quenching thiab tempering, normalizing, thermomechanical dov + tempering raws li txoj cai, thiab cov xwm txheej kuj tau teev raws li cov kev cai.
Kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg ntawm CCSFH460 steel phaj
Qauv: CCSFH460

CSFH460 steel phaj siv tus qauv: GB711-2011
Cov qauv no yog siv rau kev tsim cov hlau phaj nrog lub thickness tsis pub tshaj 150 hli rau cov nkoj, cov nkoj nuv ntses thiab marine engineering cov qauv hauv dej hiav txwv, ntug hiav txwv dej thiab hauv av navigation.
Z-kev taw qhia steel: tseem hu ua "lamellar tearing resistant steel", uas yog feem ntau hu ua Z-kev taw qhia kev ua tau zoo. Nyob rau hauv cov qauv hlau txuas nrog vuam, thaum lub thickness ntawm cov hlau phaj tsis tsawg tshaj li 40 hli thiab nws bears tensile quab yuam raws thickness kev taw qhia ntawm lub phaj, thiaj li tsis txhob lamellar tearing thaum lub sij hawm vuam, nws yog tsim nyog los siv cov hlau uas resists. lamellar tearing (feem ntau hu ua "Z"). "Rau Steel"). Cov phaj tuab muaj teeb meem lamellar tearing, yog li Z-kev taw qhia kev ntsuas yuav tsum tau ua.
CSFH460 nkoj phaj yog lub nkoj muaj zog siab. Nws tuaj yeem tsim cov khoom lag luam marine steel raws li cov neeg siv khoom xav tau hauv ntau lub tebchaws, xws li Tebchaws Meskas, Norway, Nyiv, Lub Tebchaws Yelemees, Fabkis, thiab lwm yam. Nws cov ntawv pov thawj hauv zej zog yog raws li hauv qab no:
