Ni lọwọlọwọ, awọn fasteners lori ọja ni akọkọ pẹlu irin alagbara, irin erogba, bàbà, alloy aluminiomu mẹrin iru awọn ohun elo aise..

1. Erogba irin. Si erogba, irin ohun elo ninu awọn tiwqn ti erogba lati se iyato laarin kekere erogba, irin, alabọde erogba irin, ga erogba, irin ati awọn oniwe-alloy, irin.

(1) kekere erogba irin C%≤ 0.25% China ni gbogbogbo ti a pe ni irin A3. Awọn orilẹ-ede miiran ati awọn agbegbe ni a pe ni ipilẹ 1008, 1015, 1018, 1022, bbl (Akiyesi: Drill-tailskruni gbogbogbo lo awọn ohun elo aise 1022.)

(2) alabọde erogba irin 0,25% 0,60%. Lọwọlọwọ lori ọja ni ipilẹ ko si ohun elo ti ohun elo yii.

(3) irin alloy: ni irin erogba arinrin lati ṣafikun awọn paati alloy, fifi diẹ ninu awọn abuda pataki si irin ikole: bii 35, 40 chromium-molybdenum, SCM435, 10B38. Awọn skru 12.9 ni lilo SCM435 chromium-molybdenum alloy steel, awọn paati bọtini jẹ C, Si, Mn, P, S, Cr, Mo.

2. Irin alagbara. Ipele abuda: 45, 50, 60, 70, 80. o kun pin si martensite (18% Cr, 8% Ni) ti o dara otutu resistance, ti o dara ipata resistance. a1, a2, a4 martensite (13% Cr) alailagbara ipata, agbara giga, resistance resistance to dara. c1, c2, c4430 irin alagbara, irin. 18% Cr ibinu jẹ dara julọ, ipata resistance ni okun sii ju austenite. Awọn ohun elo aise ọja lọwọlọwọ jẹ pin ni akọkọ si SUS302, SUS304, SUS316 nipasẹ ite.

3. Ejò. Awọn ohun elo ti o wọpọ fun idẹ, eleyi ti Ejò alloy. Ọja naa ni gbogbogbo lo H62, H65, H68 Ejò fun awọn ọja boṣewa.

4. Aluminiomu alloy density jẹ kekere, ṣugbọn agbara fifẹ jẹ giga pupọ, ti o sunmọ tabi paapaa diẹ sii ju irin simẹnti ti o ni ooru, ṣiṣu ti o dara, le ṣee ṣe si orisirisi awọn profaili aluminiomu, pẹlu itanna eletiriki ti o dara, gbigbe ooru ati ipata. resistance, lilo ile-iṣẹ jẹ lọpọlọpọ, iye irin keji nikan.

1. Irin alloy tun tọka si irin alloy chromium-molybdenum, gẹgẹbi SCM435, ati bẹbẹ lọ.
