a131 qib b shipbuilding daim hlau Cov Khoom Paub meej
Marine steel phaj yog structural steel siv nyob rau hauv shipbuilding. Nws suav hais tias yog marine steel thiab yuav tsum muaj peev xwm tiv taus cov teebmeem corrosive uas muaj nyob rau hauv ib puag ncig dej. Txawm hais tias feem ntau cov pa roj carbon steels tsis haum rau ib puag ncig marine, muaj ob peb marine- qib carbon steels uas tau pom zoo los ntawm cov koom haum sib txawv rau kev siv hauv nkoj tsim.
Hull structural steels yog categorized rau hauv cov chav kawm muaj zog sib txawv raws li lawv qhov tsawg kawg nkaus lub zog: ib txwm muaj zog cov qauv steels thiab siab zog steels. Maine steel daim hlau yog kub dov steel daim hlau ua raws li qhov yuav tsum tau ntawm kev faib cov koom haum rau kev tsim kho ntawm cov qauv hull. General Strength Structural Steel los ntawm Tuam Tshoj Classification Society yog categorized rau plaub qib zoo: ABD thiab E.
ASTM A131 yog cov txheej txheem qib steel phaj siv yuav luag tshwj xeeb hauv kev tsim khoom nkoj. Qib no txhais tau tias yog lub zog ib txwm muaj nrog lub zog tsawg kawg nkaus ntawm 34 KSI (235 Mpa). Cov ntawv thov muaj xws li nkoj nkoj, cov khoom siv hauv hiav txwv thiab kev tsim nkoj. Cov qib no kuj tau lees paub los ntawm American Bureau of Shipping (ABS).
