17-4PH Pepa Ikepili Mea
Nā ʻāpana
Hōʻike ʻia ka mea stainless 17-4 PH e ka ikaika hua kiʻekiʻe, ke kūpaʻa corrosion maikaʻi a me ke kūpaʻa lole kiʻekiʻe. ʻO 17-4 PH kekahi o nā kila koʻikoʻi hiki ke paʻakikī. Ua like ia me nā mea 1.4548 a me 1.4542.
Hiki ke hoʻohana ʻia ma ke ʻano haʻahaʻa me ke Kūlana H1150 a me H1025. Hāʻawi ʻia ka ikaika hopena notched maikaʻi loa i nā mahana haʻahaʻa.
Ma muli o nā waiwai mechanical maikaʻi a me ka pale ʻana i ka corrosion, ua kūpono ka mea no ka hoʻohana ʻana i nā kaiapuni kai, akā hiki ke maʻalahi i ka corrosion crevice i ka wai kai kū.
ʻO 17-4PH ka mea kaulana ʻo AISI 630.
Hoʻohana ʻia ka mea 17-4PH i ka ʻoihana kemika, ka ʻoihana lāʻau, ka ʻāpana o waho, i ka hana moku, i ka ʻenekini mīkini, i ka ʻoihana ʻaila, i ka ʻoihana pepa, i ka ʻoihana haʻuki. ʻOihana leʻaleʻa a ma ke ʻano he hoʻoheheʻe hou ʻia (ESU) i ka lewa a me Aerospace.
Inā lawa ʻole nā waiwai mechanical a me ka corrosion resistance o nā kila martensitic, hiki ke hoʻohana ʻia ka 17-4PH.

Pōmaikaʻi
ʻO kahi waiwai kūikawā o ka mea 17-4 PH ka mea kūpono no nā haʻahaʻa haʻahaʻa a me ka hoʻopili ʻana a hiki i ka approx. 315°C.
Ke kalai ʻana:Hana ʻia ka hana ʻana o ka mea ma kahi mahana wela o 1180 ° C a 950 ° C. No ka hōʻoia ʻana i ka hoʻomaʻemaʻe ʻana i ka palaoa, hana ʻia ka hoʻomaha ʻana i ka lumi me ka ea.
wiliwili:Ma mua o ka hiki ke welded ka mea 17-4 PH, pono e noʻonoʻo i ke ʻano o ka mea kumu. Ma ke ʻano paʻa, aia ke keleawe i loko o ka mea. ʻAʻole kēia e hāpai i ka pohā wela.
No ka hiki ke hana i ka kuʻihao optimum kuʻihao kūlana koi. Hiki i nā ʻoki ʻoki a i ʻole ke kuʻi ʻana ke alakaʻi i ke kūkulu ʻana i kahi notch. Pono e pale ʻia kēlā. I mea e pale ai i ka hana ʻana o nā māwae koʻikoʻi, pono e hoʻopili hou ʻia ka mea i ka hoʻonā annealing me ka ʻelemakule ma hope i loko o kahi manawa pōkole ma hope o ke kuʻi ʻana.
Inā ʻaʻohe mālama ʻia ma hope o ka wela, hiki ke ʻokoʻa loa nā waiwai mechanical-technological i ka weld seam a me ka wahi wela i ka mea kumu.
ʻO ke kūpaʻa ʻino:i ka lawa ole o na waiwai mechanical a me ka corrosion o na kila martensitic, kupono ka 17-4 PH no ka hoohana ana i na kai moana. Loaʻa iā ia kahi hui o nā mea mechanical maikaʻi loa a me ka pale ʻana i ka corrosion.
I ke kū ʻana o ke kai, hiki i ka 17-4 PH ke maʻalahi i ka ʻinoʻino. Pono kēia i ka pale hou.
Mīkini:17-4 PH hiki ke mīkini ʻia i loko o ke kūlana paʻakikī a hoʻonā-annealed. Ma muli o ka paʻakikī, ʻokoʻa ka machinability, e pili ana kēia i ke ʻano.
Hoʻomaʻamaʻa wela
Ma waena o 1020°C a me 1050°C ka mea 17-4 PH ka solution-annealed. Hoʻopili ʻia kēia me ka hoʻomaha wikiwiki - ka wai, ka aila a i ʻole ka ea. Pili kēia i ka ʻāpana keʻa o ka mea.
No ka hōʻoia ʻana i ka hoʻololi piha ʻana mai kahi austenite i kahi martensite, pono e loaʻa i ka mea ke hiki ke hoʻomaha i ka mahana o ka lumi.

Paʻa, hoʻopaʻa ʻia, hoʻonā i hoʻopili ʻia a i waho
Pōmaikaʻi o ka ʻoki ʻana
ʻO ka hanaʻana me ka saw he hana mechanical o ka mea, e hopena i ka hoʻohaʻahaʻa haʻahaʻa i manaʻoʻoleʻia a hoʻonui i ka paʻakikī no ka hale e kū nei, e like me kaʻokiʻana i ka wela.
No laila, ʻo ka mea hana i hana ʻia he ʻano homogeneous a hiki i ka lihi, ʻaʻole e loli i ka hoʻomau ʻana o ka mea.
Hiki i kēia kūlana ke hoʻopau koke i ka mea hana me ka wili a i ʻole ka wili ʻana. No laila ʻaʻole pono e hoʻohui i ka mea a hana i kahi hana like ma mua.
