I kēia manawa, ʻo nā mea hoʻopaʻa ma ka mākeke ka nui o ke kila kila, ke kila kalapona, ke keleawe, ka alumini alumini ʻehā ʻano mea maka..

1. Ke kila kalapona. I ke kalapona kila mea i loko o ka haku mele 'ana o ke kalapona e hoʻokaʻawale ma waena o haʻahaʻa kalapona kila, waena kalapona kila, kiʻekiʻe kalapona kila a me kona hao hao.

(1) hao kalapona haʻahaʻa C%≤ 0.25% Kina i kapa ʻia ʻo A3 kila. ʻO nā ʻāina a me nā ʻāina ʻē aʻe i kapa ʻia ʻo 1008, 1015, 1018, 1022, a me nā mea ʻē aʻe. (Manuahi: Drill-tailwiliwilihoʻohana maʻamau 1022 mau mea maka.)

(2) hao kalapona waena 0.25% 0.60%. I kēia manawa ma ka mākeke, ʻaʻohe hoʻohana o kēia mea.

(3) ke kila kila: i loko o ke kila kalapona maʻamau e hoʻohui i nā mea hoʻohui, e hoʻohui i kekahi mau hiʻohiʻona kūikawā i ke kila hana: e like me 35, 40 chromium-molybdenum, SCM435, 10B38. 12.9 papa wiliwili e hoʻohana ana i ka SCM435 chromium-molybdenum alloy steel, ʻo nā mea nui ʻo C, Si, Mn, P, S, Cr, Mo.

2. Ke kila kila. Papa hiʻona: 45, 50, 60, 70, 80. mahele nui i martensite (18% Cr, 8% Ni) maikaʻi wela kū'ē, maikai corrosion kū'ē. a1, a2, a4 martensite (13% Cr) ʻoi aku ka nāwaliwali o ka corrosion, ka ikaika kiʻekiʻe, ke kūpaʻa maikaʻi. c1, c2, c4430 kila kila. ʻOi aku ka maikaʻi o ka 18% Cr, ʻoi aku ka ikaika o ka pale ʻana ma mua o ka austenite. Hoʻokaʻawale ʻia ka mākeke o kēia manawa i SUS302, SUS304, SUS316 e ka papa.

3. Ke keleawe. Nā mea maʻamau no ke keleawe, poni keleawe. Hoʻohana maʻamau ka mākeke H62, H65, H68 keleawe no nā huahana maʻamau.

4. He haʻahaʻa ka nui o ka alumini alumini, akā ʻoi aku ka kiʻekiʻe o ka ikaika compressive, kokoke a ʻoi aku paha ma mua o ka hao hoʻoheheʻe wela, ka plasticity maikaʻi, hiki ke hana ʻia i nā ʻano like ʻole o ka alumini, me ka conductivity uila maikaʻi, ka hoʻoili wela a me ka corrosion. kū'ē, hoʻohana 'oihana nui loa, ka nui o ke kila lua wale.

1. ʻO ke kila kila kekahi e pili ana i ke kila kila chromium-molybdenum, e like me SCM435, etc.

Nā mea maka maʻamau no nā mea hoʻopaʻa

(A) ke kila kalapona, ke kila kila, ke kila kila kūikawā

1, bolts, screws, screws 3.6 grade, 4.6 grade, 4.8 grade, 5.6 grade, 5.8 grade, 6.8 grade general choice of carbon steel, no heat treatment process; 8.8 papa, 9.8 papa koho maʻamau o ka haʻahaʻa kalapona kaiapuni i hoʻohuihui kila a waena kalapona kila, kinai ʻia a huhū; 10.9 papa koho maʻamau o ka haʻahaʻa a me ke kalapona kila kila a i ʻole ke kila kila, kinai ʻia a hoʻomāmā; 12.9 papa koho maʻamau o ke kila kila, kinai ʻia a me ka huhū. ʻO ka hoʻohenehene.

2, nā nati 4, 5, 6 koho maʻamau o ke kila kalapona, akā hiki ke ʻoki maʻalahi i ka hana kila, ʻaʻohe kaʻina hana wela; 8, 9, koho maʻamau o ke kila kalapona maʻamau, kinai ʻia a me ka huhū; 10, 12 e hoʻonui i nā waiwai kino, inā pono, hiki ke hoʻonui i ka haku mele, kinai ʻia a me ka huhū.

3, ʻO ka hoʻopaʻa ʻana i nā wili 14H koho maʻamau i ke kila kalapona, ʻaʻohe kaʻina hana wela; ʻO 22H, 33H ke koho maʻamau i ke kila kalapona, kinai ʻia a huhū; 45H koho maʻamau i ke kila kila, kinai ʻia a me ka huhū.

4, ʻO ka papa pālahalaha HV140 ke koho maʻamau i ke kila kalapona haʻahaʻa; HV300 koho maʻamau kalapona kila, pono wela kaʻina hana.

5,ʻO nā kui kuʻi ponoʻī/drill-tail nails i koho ʻia mai ke kila kalapona waena e like me SWRCH22A, pono e carburized ka papa honua.

6, ʻano niho ʻano, holoi laka serrated, ʻano hana, ʻano nalu ʻano holoi holoi e koho maʻamau 65Mn

7, koho ʻia nā mea holoi elastic i ke kila kila 70/65Mn/60Si2Mn, kinai ʻia a huhū.

8, hiki i ka pine ke koho maʻamau i ke kila kalapona 35 #, kinai ʻia a me ka huhū HRC28-38, 45 #, kinai a me ka HRC38-46; ke kila kila 30CrMnSiA, kinai ʻia a me ka huhū HRC35-41; kila kūikawā 1Cr13/2Cr13, Cr17.i2, 1Cr18.I9Ti

(B) mea kila kila

Mea hao hao:uʻa kila kila mea i Q215 a me Q235 a me 25 a me 45 pu me ka mea kila, i ke kaula ma waena o ka bolt i kekahi manawa e pono ai ka hui nui, a laila hiki iā ʻoe ke hoʻohana i ka 15Cr a me 20Cr a pēlā aku a me 30CrMri kēia mea hao, no laila i nā mea mechanical o ka e hoʻomaikaʻi ʻia ka bolt. Loaʻa iā ia he 9 haku mele, ni, cu, c, s, si, p, mn, cr. nā mea kila kila: 201, 304, 316, 304L, 316L, 2205, 2507, 310S, 321, 904L, 667 a pēlā aku.

Nā ʻano hoʻolauna: 302HQ kahi o ke kumu nui e paʻi ai i nā kui; ʻO SUS304, A2 kekahi inoa ʻē aʻe no ia, ʻo ka mea hana nui no nā bolts kuhiliʻole, nā wili kila kuhiliʻole, nā mea holoi kila kila a me nā nati kila kila, ʻoi aku ka nui o ka waiwai o ka ikaika ma ka ʻaoʻao o luna; ʻO SUS316 a me SUS316L, i ʻike ʻia ʻo A4, ʻoi aku ka maikaʻi ma mua o A2, nā bolts stainless steel, stainless steel screws, stainless steel washers, the Stainless steel nuts production, hiki ke like kēia waiwai helu ikaika a me A2, akā hiki ke lilo i kahi ʻoi aku ka ikaika ma mua o A2.

Hana nui ʻo Nanning Aozhan Hardware Fastener Co., Ltd. i nā bolts stainless steel, stainless steel nuts, washers, self-tapping nails, drill-tail nails, etc. Inā makemake ʻoe e ʻike hou aʻe e pili ana i nā mea paʻa kila kila, e hoʻouna i leka uila iinfo@aozhanfasteners.com, hauʻoli mākou e hāʻawi iā ʻoe i nā pane!
