Ke kila kila 409

He kila Ferritic 409 e hāʻawi ana i nā waiwai mechanical maikaʻi a me ka pale ʻana i ka corrosion kiʻekiʻe. Manaʻo pinepine ʻia ʻo ia he kila stainless chromium, me nā noi i nā ʻōnaehana exhaust o nā kaʻa a me nā noi e koi ai i ka weldability.

Loaʻa nā kila 409 i nā ʻano paʻa loa, e like me nā māka S40930, S40920 a me S40910. Hāʻawi ʻia ka paʻa o kēia mau māka e ka hiki ʻana o ka niobium, titanium, a i ʻole nā ​​​​mea ʻelua, i ke ʻano o nā kila.
