Dab tsi yog Shipbuilding Steel Phaj
Shipbuilding steel phaj hais txog kub-dov hlau rau kev tsim cov qauv nkoj tsim ua raws li cov cai ntawm kev tsim kho vaj tse. Feem ntau siv raws li kev txiav txim tshwj xeeb steel, teem caij, muag khoom, lub nkoj nrog rau nkoj daim hlau, hlau thiab lwm yam.
Shipbuilding Steel Classification
Shipbuilding steel phaj tuaj yeem muab faib ua lub zog dav dav hlau thiab lub zog muaj zog steel raws li nws qhov tsawg kawg nkaus taw tes lub zog.
JINDALAI cov khoom siv thiab xa tawm 2 hom nkoj steel, nruab nrab lub zog shipbuilding phaj thiab siab zog shipbuilding phaj. Tag nrho cov hlau phaj khoom tuaj yeem tsim tau raws li Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, thiab lwm yam.
Kev siv Shipbuilding Steel
Shipbuilding ib txwm siv cov txheej txheem steel phaj los tsim cov nkoj hulls. Niaj hnub nimno steel phaj muaj zog tensile ntau dua li lawv cov neeg ua ntej, ua rau lawv zoo dua rau kev tsim kho ntawm cov thawv loj loj. Ntawm no yog qhov zoo ntawm Shipbuilding Phaj Siab corrosion resistant steel phaj yog zoo meej steel hom rau roj tso tsheb hlau luam, thiab thaum siv nyob rau hauv shipbuilding, lub nkoj nyhav tsawg dua rau tib lub peev xwm nkoj, roj nqi thiab CO2emission yuav raug txo.
