RINA Sehlopha sa AH40 Marine Steel Plate

Letlapa la tšepe la marine le bolela litšepe tsa sebopeho tse sebelisoang moahong oa sekepe. E nkoa e le boemo ba leoatle 'me e tlameha ho khona ho hanela liphello tse senyang tse tloaelehileng tikolohong ea metsi. Ho finyella sena, likarolo tse khethehileng tsa alloying li eketsoa lihlopheng tsena e le ho sireletsa khahlanong le corrosion.Le hoja boholo ba tšepe ea carbon e sa tšoanelehe bakeng sa tikoloho ea leoatle, ho na le litšepe tse ngata tsa carbon grade tse amohetsoeng ke mekhatlo e fapaneng bakeng sa likopo tsa ho haha ​​likepe.

Litšepe tsa sebopeho bakeng sa likepe tsa likepe li arotsoe ka lihlopha tsa matla ho ea ka matla a eona a fokolang a lihlahisoa: matla a kakaretso a tšepe ea mohaho le matla a phahameng a tšepe ea mohaho. Letlapa la tšepe la Maine le bua ka poleiti ea tšepe e chesang e kolobisitsoeng e hlahisoang ho latela litlhoko tsa sechaba sa classication bakeng sa kaho ea meaho ea sekepe sa sekepe.
