Type 440 Stainless Steel, i kapa ʻia ʻo "razor blade steel," he kila chromium kiʻekiʻe-carbon paʻakikī. Ke waiho ʻia ma lalo o ka hoʻomaʻamaʻa wela, loaʻa ia i nā pae paʻakikī kiʻekiʻe loa o kēlā me kēia papa o ke kila kila. ʻAno 440 Stainless Steel, e hele mai ana i nā māka like ʻole ʻehā, 440A, 440B, 440C, 440F, hāʻawi i ka pale ʻana i ka corrosion maikaʻi me ke kūʻē abrasion. Hiki ke maʻalahi nā māka a pau i ko lākou kūlana annealed, hāʻawi pū lākou i ke kū'ē i nā waikawa haʻahaʻa, alkalis, nā meaʻai, ka wai hou, a me ka ea. Hiki ke hoʻopaʻakikī ʻia ke ʻano 440 i ka harness Rockwell 58.
Mahalo i kēlā me kēia mākau waiwai koʻikoʻi, hiki ke loaʻa nā māka āpau o Type 440 Stainless Steel i nā huahana like ʻole me:
- Nā pine pivot
- Nā mea hana niho a me nā mea hana
- ʻO nā pahi pahi kiʻekiʻe
- Noho kiwi
- Nozzles
- ʻO nā pulu ʻaila
- ʻO nā bearings element rolling
Hoʻokumu ʻia kēlā me kēia papa o Type 440 Stainless Steel i kahi ʻano kemika kū hoʻokahi. Pono e hoʻomaopopo ʻia ʻo ka ʻokoʻa nui wale nō ma waena o nā māka ka pae o Carbon
