ʻO 9Cr18 a me 440C nā ʻano ʻelua o ka martensitic stainless steel, ʻo ia hoʻi ua paʻakikī lāua ʻelua e ka mālama wela a ʻike ʻia no ko lākou ikaika kiʻekiʻe a me ke kūpaʻa corrosion.
9Cr18 a440Cpili i ka ʻāpana o nā kila stainless martensitic, kaulana no ko lākou ʻano paʻakikī a paʻa i ke kūpaʻa ʻana ma hope o ka hoʻopau ʻana, e kūpono iā lākou no nā noi kiʻekiʻe. Hiki i nā mea ʻelua ke hoʻokō i nā pae paʻakikī o HRC60 ° a ma luna aʻe ma hope o ka mālama ʻana i ka wela.9Cr18 ka mea i ʻike ʻia e kona kiʻekiʻe kalapona a me ka chromium maʻiʻo, e hoʻolilo iā ia i mea kūpono no ka hana ʻana i nā mea i hoʻopaʻa ʻia i ka lole kiʻekiʻe, nā ukana kaumaha, a me nā kaiapuni non-corrosive, e like me ka mana aunoa ʻāpana valve. Eia nō naʻe, maʻalahi ia i ka oxidation ma ka ʻike ʻana i ka wai a i ʻole ka mahu wai, pono e hoʻohana ʻia i nā wahi kahi e hoʻemi ʻia ai ka pili ʻana me ka makū.
