17-4PH mau mea waiwai

17-4PH he chromium-nickel-copper precipitation hardening martensitic stainless steel.ʻO kēia papa o ke kila kila he mau waiwai e like me ka ikaika kiʻekiʻe, ka paʻakikī a me ka pale ʻana i ka corrosion.Ma hope o ka hoʻomaʻamaʻa wela, ʻoi aku ka maikaʻi o nā waiwai mechanical o ka huahana, a hiki i ka ikaika compressive ke piʻi i kahi kiʻekiʻe e like me 1100-1300MPa (160-190ksi).ʻAʻole hiki ke hoʻohana ʻia kēia māka ma nā mahana ʻoi aʻe ma mua o 300°C (572°F) a i ʻole haʻahaʻa loa.Loaʻa iā ia ka pale corrosion maikaʻi i ka lewa a me ka dilute acid a i ʻole nā paʻakai.Hoʻohālikelike ʻia kona kūpaʻa corrosion me 304.
