Hoʻolauna o 17-4ph Stainless Steel

ʻO 17-4 ka pā kila kila (630) he chromium-copper precipitation hardening stainless steel material i hoʻohana ʻia no nā noi e koi ana i ka ikaika kiʻekiʻe a me ka pae haʻahaʻa o ka pale ʻana i ka corrosion. ʻO ka ikaika kiʻekiʻe
mālama ʻia ma kahi o 600 degere Fahrenheit (316 degere
Celsius).

Na Waiwai Nui

ʻO ke kila kila Alloy 17-4 PH ka ua paʻakikī martensitic stainless steel me Cu a me Nb/Cb hoʻohui. Hoʻohui ka papa i ka ikaika kiʻekiʻe, ka paʻakikī (a hiki i 572°F / 300°C), a me ka corrosion.
kūʻē.

Pale ʻino

ʻOi aku ka maikaʻi o ka Alloy 17-4 PH ma mua o kekahi o nā kila kulika paʻakikī maʻamau a hoʻohālikelike ʻia me Alloy 304 ma ka hapa nui o ka media.

Inā loaʻa nā pilikia o ka pohā o ke koʻikoʻi, pono e koho ʻia nā wela kahiko ma luna o 1022°F (550°C), ʻoi aku ka maikaʻi o 1094°F (590°C). ʻO 1022°F (550°C) ka mahana hoʻoluʻu maikaʻi loa i loko o ka media chloride.

ʻO 1094°F (590°C) ka wela hoʻoheheʻe maikaʻi loa ma ka media H2S.

Hoʻopili ʻia ka huila i ka crevice a i ʻole ka hoʻouka kaua ʻana inā ʻike ʻia i ka wai kai kūpaʻa no kekahi manawa lōʻihi.

He pale ʻino ia i kekahi mau mea kemika, ka aila, ka pepa, ka waiu a me nā ʻoihana hana meaʻai (e like me ka 304L grade).
