I le taimi nei, o faʻamau i luga o le maketi e masani lava ona aofia ai le uamea, uamea carbon, apamemea, alumini alumini ituaiga e fa o mea mata..
1. Uamea kabone. I mea uamea carbon i le tuufaatasiga o le kaponi e iloagofie ai le va o le kaponi uamea maualalo, medium carbon uamea, maualuga carbon uamea ma lona uʻamea uamea.
(1) uamea maualalo C%≤ 0.25% Saina e masani ona taʻua A3 sila. O isi atunuu ma itulagi e masani ona taʻua 1008, 1015, 1018, 1022, ma isi.. Faʻaaogaina i le 4.8 grade siku ma 4 vasega nati, sikulima laiti ma isi oloa e aunoa ma tulaga malosi. (Manatua: Drill-tailfa'ailogae masani ona faʻaaogaina 1022 mea mataʻutia.)
(2) uamea kaponi feololo 0.25% 0.60%. I le taimi nei i luga o le maketi e leai se faʻaogaina o lenei mea.
(3) u'amea u'amea: i le uamea carbon masani e fa'aopoopo vaega u'amea, fa'aopoopo nisi uiga fa'apitoa i le uamea faufale: pei o le 35, 40 chromium-molybdenum, SCM435, 10B38. 12.9 fa'ailoga fa'aoga e fa'aaoga ai le sila SCM435 chromium-molybdenum, o vaega autu o C, Si, Mn, P, S, Cr, Mo.
2. Uamea uamea. Vasega uiga: 45, 50, 60, 70, 80. e masani ona vaevaeina i martensite (18% Cr, 8% Ni) lelei le vevela, faʻafefe lelei. a1, a2, a4 martensite (13% Cr) vaivai le pala, malosi maualuga, lelei le ofuina. c1, c2, c4430 uamea uamea. 18% Cr le fiafia e sili atu, e sili atu le malosi o le teteʻe nai lo austenite. Ole maketi o lo'o iai nei e masani ona vaevaeina ile SUS302, SUS304, SUS316 ile vasega.
3. Kopa. Mea masani mo apamemea, lanu viole apamemea. O le maketi e masani ona faʻaaogaina H62, H65, H68 kopa mo oloa masani.
4. alumini alumini density e maualalo, ae o le compressive malosi e matua maualuga, latalata i pe sili atu foi nai lo le vevela-tetee uʻamea lafo, palasitika lelei, e mafai ona faia i le tele o talaaga otooto alumini, ma conductivity lelei eletise, fesiitaiga vevela ma corrosion. teteʻe, faʻaaogaina fale gaosimea e matua tele lava, o le aofaʻi o le uamea lona lua.
- Alloy uamea e faasino foi i chromium-molybdenum uamea uamea, pei o le SCM435, ma isi.
Mea masani masani mo fa'amau
