1. fa'avasegaga
E tusa ai ma le aofaʻi o le carbon content, e mafai ona vaevaeina le carbon steel i vaega nei e tolu:
1) Low carbon sila C% ≤ 0.25
2) Medium carbon sila 0.25
3) High carbon sila C%> 0.6
Pusa maualalo
Mid-Carbon
High-Carbon
2. su'esu'ega weldability
Ole aofa'i ole kaponi ose fa'amatalaga taua mo le atina'eina ole fa'agasologa ole uelo.Aʻo faʻateleina le kaponi, faʻateleina le malosi ma le maʻaʻa, aʻo faʻaitiitia le palasitika ma le malosi, aʻo faʻateleina le atuatuvale.E tusa ai ma le tautala, o le maualalo o le carbon carbon, o le sili atu lea o le weldability, o le mea lea, o le carbon content o le tulaga masani lea mo le faʻamasinoina o le faigata o le uʻamea carbon steel, ma e tatau ona faʻaaogaina faiga faʻapipiʻi eseese mo mea eseese carbon.
3. Fa'agasologa uelo
O le filifilia o mea faʻapipiʻi carbon steel e mulimuli i le mataupu faavae o le "tusa le malosi"
1. Low carbon steel (e masani ona ta'ua o mild steel)
Fa'ailoga u'amea masani e pei ole Q235 (e masani ona ta'ua o le A3 sila), Q255, ma isi, e masani lava e le faia ni fa'apitoa fa'apitoa pe a uelo, e le o le fa'avevela po'o le fa'avela.
2. Medium carbon steel
u'amea masani fa'aaogaina e pei o le 30 #, 45 #, ma isi, 45 # o le meafaitino mo le gaosiga o lau va'ai ma faila, e sili ona lelei le fa'aogaina o mea fa'apipi'i maualalo-hydrogen fa'atasi ai ma tete'e lelei ta'eta'e, fa'amumu 100-200 °C;Afai e le faigofie e preheat, e mafai ona filifilia Cr-Ni austenitic uamea uʻamea uʻamea.
3. Sila maualuga carbon
Fa'aaoga masani togi uamea e pei ole 60Si2Mn, T8, T10 ma isi.60Si2Mn o se uʻamea tautotogo masani, e masani lava e le faia togafitiga uelo, e masani ona faʻaaogaina e pei o le toe uelo, e tatau ona 250-350 °C preheating, e tatau ona samala uelo e aveesea ai le atuatuvale, ma 650 °C post-vevela togafitiga, e mafai foi. filifili Cr-Ni austenitic uamea uʻamea uʻamea
Fa, u'amea lima u'amea lima u'amea taua tele:

2. O le susu, suauʻu, 'ele, ma isi mea i luga o le mea faʻavae e tatau ona aveese
3. Fa'aaoga le auala agai i tua e uelo ai e aloese ai mai le stomata i le amataga
E tatau ona fa'aogaina le uelo pu'upu'u, e pei o fasipepa fa'afefete, ma e le tatau ona sili atu i le 3 taimi le lautele o le uaea.
