Q345D槽鋼不像一般金屬間化合物具有較負(fù)電位，不會形成電化學(xué)腐良中的強(qiáng)陰極，使合金保持了較高的耐蝕性。并且純鋁中添加錳以會使一部分8轉(zhuǎn)變成16，當(dāng)這種針狀的八轉(zhuǎn)成片狀的以后，構(gòu)成了一個(gè)更弱的陰極相，也不易破表面的氧化膜。因此添加少量銅有利于將點(diǎn)蝕變?yōu)槿娓g。

盡管為兩相八合金，但其耐蝕性很高，在大氣中和工業(yè)純鋁相近，在海水中與純鋁相同，在稀鹽酸溶液的耐蝕性則比純鋁還好，但次于八合金退火狀態(tài)。而其強(qiáng)度于純鋁，達(dá)到170，  

Q345D槽鋼塑性仍很好，焊接性能也很好。在鋁合金船舶上常用于艙室內(nèi)壁等內(nèi)裝結(jié)構(gòu)。
