1. Taw qhia rau DH32 steel phaj:
DH32 steel phaj yog lub zog muaj zog steel phaj siv hauv kev lag luam shipbuilding thiab ua raws li cov txheej txheem kev faib tawm hauv zej zog uas tau teev tseg los ntawm International Maritime Organization. DH32 steel phaj muaj qhov toughness zoo thiab lub zog thiab tsim nyog rau kev tsim cov qauv ntawm cov nkoj, xws li hulls, nkoj decks thiab lwm yam qauv nkoj.
2. Cov khoom tseem ceeb thiab cov khoom ntawm DH32 steel phaj:
Cov tshuaj muaj pes tsawg leeg ntawm DH32 steel phaj feem ntau suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), txhuas (Al), titanium (Ti) thiab lwm yam. Raws li qhov yuav tsum tau muaj ntawm cov koom haum sib txawv, nws cov khoom siv kho tshuab thiab cov khoom siv hlau yuav txawv. Feem ntau hais lus, lub zog tensile ntawm DH32 steel phaj yog nruab nrab ntawm 440 thiab 590MPa, thiab lub zog tawm los yog siab dua 315MPa.
3. Kev ua tau zoo ntawm DH32 steel phaj:
DH32 steel phaj muaj kev ua tau zoo thiab tuaj yeem ua tiav los ntawm ntau yam txheej txheem, xws li txiav, khoov, dov, vuam, thiab lwm yam. Thaum siv DH32 steel phaj rau vuam, yuav tsum tau them nyiaj rau kev tswj qhov kub thiab txias thaum lub sij hawm vuam txheej txheem. los xyuas kom meej weld zoo thiab cov khoom ua tau zoo.
