Ke hōʻike ʻia e nā ʻenekinia 410 kila kila no ka ikaika kiʻekiʻe, nā ʻāpana wela-e like me nā kino valve hydraulic, nā hale pahū, a i ʻole nā winch shaft-ʻaʻole lākou e koho wale i kahi mea. Hāʻawi lākou i kahi hoa hana e hoʻomaopopo i ke ʻano o ka hana martensitic o 410 ma lalo o ke koʻikoʻi, pehea ke koi ʻana o kona pale ʻana i ka corrosion i ka mana pololei o ka ʻili, a no ke aha e ʻoi aku ai ka paʻakikī o ka paʻakikī paʻakikī ma mua o nā helu tensile wale nō.
Ma laila ka ʻike e hoʻokaʻawale ai i nā mea hoʻolako mai nā hale hana. Ma ka QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ua hana mākou ma luna o 12,000 410 mau ʻāpana kila kila no ʻAmelika ʻAmelika ʻĀpana ʻaila pauma mai ka makahiki 2021-ʻo kēlā me kēia mea e koi ana iā Rockwell C42-48 paʻakikī ma hope o ke kinai ʻana a me ka hoʻonā ʻana, ± 0.015 mm geometric tolerances ma nā maka sila, a me ka traceability piha i ka ASTM A276 raw material. Ua ʻike mākou i nā mea kūʻai aku e hōʻole i nā ʻāpana ma muli o ka micro-cracking kokoke i nā kīʻaha koi ma hope o ka mālama ʻana i ka wela-a aʻo ʻia e hoʻololi i nā ala hana a me nā pōʻai pre-heat e like me ia. Ua ʻike pū mākou i ka poʻe kūʻai aku i ka nānā ʻole ʻana i ka maʻi nickel haʻahaʻa o 410 i mea maʻalahi i ka hoʻouka intergranular i nā wahi waiwai chloride ke ʻole ka passivated pololei. ʻAʻole kēia he mau footnote puke. ʻO lākou nā haʻawina kula i kālua ʻia i kēlā me kēia 410 hale hana kila kila kaʻina holo mākou.
ʻAʻole koho ka pololei - ua kūkulu ʻia i loko o ke ʻano o ka alloy
Hāʻawi ka 410 stainless steel i ka ikaika ma o ka hoʻololi martensitic-ʻaʻole nā kiʻi ʻoniʻoni chromium oxide. ʻO ia ke ʻano o kāna hana e pili ana i ʻekolu mau ʻano hoʻololi paʻa: ka haku mele (ʻoi aku ke kalapona a me ke koena chromium), ka mōʻaukala wela, a me ka hoʻopau mīkini. ʻAʻole hōʻoia ka palapala wili maʻamau i ka paʻakikī paʻa. Hoʻokumu mākou i 410 billets i hōʻoia ʻia iā AMS 5504 a hōʻoia i kēlā me kēia wela me ka spectroscopy OES ma mua o ka hana ʻana. Inā piʻi ke kalapona ma luna o 0.15%, hoʻoponopono mākou i nā uku hoʻopau. Inā hāʻule ka chromium ma lalo o 11.5%, hōʻailona mākou i ka pūʻulu-ʻoiai inā e kūpono ana ia i ka hapa liʻiliʻi o ASTM-no ka mea, ʻaʻahu ka honua maoli i nā plummets ola.
Hoʻohui pololei mākou i ka mālama wela i kā mākou kaʻina hana CNC. Hele nā ʻāpana mai nā kikowaena hoʻohuli i nā kapuahi maloʻo ma lalo o 90 mau minuke-ʻaʻohe ʻike ambient. Hoʻohana ka Quenching i ke kinoea nitrogen ma ka wikiwiki i hoʻomalu ʻia, ʻaʻole ka aila a i ʻole ka wai, e hoʻopau ana i nā pilikia distortion ma nā hale cylinder pā lahilahi. Hana ʻia ka hana ʻino i loko o 4 mau hola ma hope o ke kinai ʻana, ʻaʻole i nā lā ma hope. No ke aha mai? No ka mea, ua hoʻohuli ʻole ʻia ka austenite paʻa ma waho o kēlā puka aniani, e hoʻolei ana i ka paʻakikī hope a me ke kūpaʻa ʻana. ʻAʻole hiki ke kūʻai ʻia kēia pae o ka hoʻopaʻi metallurgical ke hoʻopaʻa ʻia kāu ʻāpana i 3,000 psi a i ʻole ka hoʻololi ʻana ma lalo o nā ukana winch 15-ton.
Hoʻoponopono ka hoʻohui kū pololei i ka mea i haki ʻia e outsourcing
ʻO kekahi mau mea hoʻolako i waho i ka hoʻolei ʻana, ka mīkini, a me ka mālama wela e hoʻokaʻawale i nā mea kūʻai aku. Hoʻokumu ia i nā wahi makapō: ʻaʻole ʻike ka hale hana i kāu kelepona GD&T; ʻAʻole hiki i ka mea hoʻomaʻamaʻa wela ke ʻike i kāu mau koi hoʻopau ili; loaʻa ka mea hoʻopau i nā ʻāpana me ka unahi like ʻole a i ʻole nā papa decarb. Loaʻa iā mākou nā pae āpau ʻekolu—ma hoʻokahi hale hōʻoia ISO 9001 ma Qingdao.
- Ke hoolei ana: Nā hale hoʻoheheʻe one 410 me ka mana hoʻopaʻa paʻa kuhikuhi-e hoʻemi ana i ka porosity emi i loko o nā ʻāpana haʻahaʻa koʻikoʻi e 62% e kūʻē i nā poni maʻamau.
- Mīkini: Nā kikowaena CNC 5-axis me ka hoʻāʻo ʻana i loko o ke kaʻina hana pololei no ka ulu wela i ka wā ʻoki lōʻihi ma nā lua piston rod 120-mm-diameter.
- Hoʻopau: Loaʻa nā ʻili uila i ka Ra ≤ 0.4 µm ma nā ʻili e hoʻopaʻa ʻia—hōʻoia ʻia me nā profilometers, ʻaʻole nā manaʻo ʻike maka.
ʻAʻole pili kēia i ka maʻalahi. E pili ana i ka pale ʻana i nā ʻano hemahema ʻaʻohe mea kūʻai aku: kahi kīnā hoʻoheheʻe i uhi ʻia e ka mīkini mīkini, ka helu ʻana i ka warp wela wela ma ke ʻano he hewa fixture, a i ʻole kahi kiʻi passivation i wehe ʻia i ka wā deburring. Ke kauoha ʻoe mai kahi ʻoiaʻiʻo 410 hale hana kila kila, loaʻa iā ʻoe hoʻokahi hui e kuleana no ke kaulahao holoʻokoʻa-mai ka metala i hoʻoheheʻe ʻia a hiki i ka hōʻoia hana.
ʻO ka hōʻoia o ka honua maoli e paʻi i nā kikoʻī pepa i kēlā me kēia manawa
Hoʻāʻo mākou i nā ʻāpana 410 e like me nā mea hoʻohana hope - ʻaʻole i nā kūlana ASTM wale nō, akā i ke koʻikoʻi noi. Loaʻa ka hoʻāʻo hydrostatic proof ma 1.5x i helu ʻia i kēlā me kēia hale valve kaomi, me ka nānā ʻana i ka dye-penetrant o nā wahi hoʻoponopono weld-repair. Ke holo nei kēlā me kēia huila huila winch center i kahi pōʻai hoʻopaʻa hoʻopaʻa ʻia he 72-hola e kūʻē i nā ʻaoʻao 42CrMo4 paʻakikī—ana ana i ka pohō nui, hoʻololi ʻino o ka ʻili, a me ka hohonu gradient micro-hardness. Hoʻopaʻa mākou i nā hopena ma ka helu ʻāpana. Loaʻa iā ʻoe ka ʻikepili - ʻaʻole wale kahi hōʻailona "pass/fail".
Nīnau pinepine ka poʻe kūʻai: "Hiki iā ʻoe ke paʻa i ka ± 0.005 mm ma kahi lāʻau 300-mm-lōʻihi 410?" ʻAe—akā inā mākou e mīkini iā ia i ʻelua hoʻonohonoho: hoʻohuli ʻoʻoleʻa i kahi lathe paʻa, a laila hoʻopau i ka wili ma hope o ka hoʻomaha ʻana i ke kaumaha ma 650°C. E haʻi aku mākou iā ʻoe ma mua. ʻAʻole mākou e ʻōlelo i kahi hoʻomanawanui ʻaʻole hiki iā mākou ke paʻa ma waena o 500 mau ʻāpana. A inā makemake kāu kaha kiʻi i kahi radius 0.2-mm kahi e koi ai ka naʻau notch o 410 i 0.5 mm-e hōʻike mākou iā ʻoe i ka pakuhi mechanics fracture a manaʻo i ka hoʻololi ma mua o ka ʻoki ʻana i ka metala.
Hoʻomaka ka hilinaʻi ma 410 stainless steel ma mua o ka lele ʻana o ka chip mua. Hoʻomaka ia me ka ʻike pehea e pane ai ka alloy-ʻaʻole pehea e pane ai. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mālama mākou i kēlā me kēia 410 hale hana kila kila kauoha ma ke ʻano he hui metala. Hāʻawi mākou i nā ʻāpana pololei. Akā ʻo ka mea nui, hāʻawi mākou i ka wānana-dimensional, mechanical, and delivery. No ka mea ʻaʻole hāʻule nā ʻōnaehana koʻikoʻi mai nā mea ʻino. Hāʻule lākou mai nā loli i mālama ʻole ʻia. A ola kēlā mau ʻano i nā kikoʻī a mākou e mālama ai.
