Taw qhia rau ABS, DNV, CCS, NK AH40, DH40, EH40, FH40 Mild Steel Phaj / Ntawv rau Shipbuilding

Classification Societies thiab Qib

ABS (American Bureau of Shipping), DNV (Det Norske Veritas), CCS (China Classification Society), thiab NK (Nippon Kaiji Kyokai) yog qhov zoo - lees paub kev faib cov koom haum hauv kev lag luam shipbuilding. AH40, DH40, EH40, thiab FH40 yog cov qib sib txawv ntawm cov hlau me me / cov ntawv siv rau kev tsim nkoj. Cov tsiaj ntawv "A", "D", "E", thiab "F" feem ntau sawv cev rau ntau theem ntawm kev ua tau zoo thiab kev ua tau zoo, thiab tus lej "40" qhia qhov tsawg kawg nkaus lub zog (hauv ksi lossis kwv yees li 275MPa thaum hloov dua siab tshiab) ntawm hlau.

Tej kev siv

Cov phaj hlau / cov ntawv no yog siv rau hauv ntau qhov chaw ntawm cov qauv nkoj. Lawv yog siv los tsim lub hull, decks, bulkheads, thiab lwm yam khoom. Piv txwv li, nyob rau hauv kev tsim kho ntawm ib tug loj-scale tanker, lub hull plating tej zaum yuav siv cov high-lub zog me me steel daim hlau los tiv thaiv lub sab hauv thiab sab nraud pressures exerted los ntawm cargo thiab dej hiav txwv. Nyob rau hauv ib lub thawv nkoj, lub lawj thiab tuav cov qauv kuj yog ua los ntawm cov hlau zoo li no los txhawb qhov hnyav ntawm cov thawv ntim khoom thiab cov khoom hnyav thaum caij nkoj.

Mechanical Properties of Steel Phaj / Ntawv

Lub zog muaj zog

Qhov tsawg kawg nkaus lub zog ntawm AH40, DH40, EH40, thiab FH40 qib yog nyob ib ncig ntawm 275MPa. Lawv lub zog tensile sib txawv nyob ntawm qib thiab cov kev xav tau tshwj xeeb. Piv txwv li, lub zog tensile ntawm cov qib no feem ntau yog nyob ib ncig ntawm 400 - 520MPa. Qhov siab-lub zog ntawm cov hlau no ua rau lawv dais cov khoom hnyav thiab kev ntxhov siab los ntawm cov nkoj, xws li cov khoom zoo li qub ntawm lub nkoj nws tus kheej qhov hnyav thiab cov khoom thauj, nrog rau cov dynamic loads los ntawm nthwv dej, cua, thiab nkoj txav.

Lub elongation ntawm so kuj yog ib qho tseem ceeb ntawm cov cuab yeej cuab tam. Cov qhab nia no feem ntau muaj qhov elongation ntawm ib ncig ntawm 22 - 25% (nyob ntawm seb cov khoom lag luam tshwj xeeb thiab cov kev sim ntsuas). Qhov ductility no tso cai rau cov hlau kom deform plastically rau qee qhov ua ntej tawg, uas yog qhov tseem ceeb rau kev nqus lub zog thaum muaj kev cuam tshuam xws li kev sib tsoo thiab tiv thaiv kev ua tsis tiav ntawm lub nkoj cov qauv.
