AISI SAE 4130 4140 4145H Uamea Taamilomilo Pa O'o'o
Vaega
4130 4135 4140 4145H pa uamea o se uʻamea uʻamea maualalo.E iai i latou i le Chrome-Molly alloy lea e iai le chromium ma le molybdenum e avea ma mea faʻamalosi.
4130 lapotopoto pa uamea o loʻo i ai le malosi galue lelei, faʻaitiitia le faʻagasologa o gaioiga, ma le sili atu o le vaivai.E a'afia i le vaega o le feololo i le maualuga fa'amalosi malosi uamea.A maeʻa togafitiga vevela, 4140 o loʻo i ai le malosi lelei ma le atoatoa o mea faʻainisinia, lelei le gaioiga gaioiga, ma le maualuga o le gaosiga.O le vevela o le tautua e 427 tikeri Celsius.
4140 e maualuga le malosi, faʻamalosi malosi, faigata, ma faʻalavelave i le taimi o le tineia.E maualuga le malosi fetolofi ma le malosi tumau i le maualuga o le vevela.Fa'aaogaina mo le gaosiga o mea fa'apipi'i e mana'omia ai le malosi maualuga ma le tele o vaega tineia ma fa'afefeteina nai lo le 4135 sila, e pei o mea tetele mo le locomotive traction, fa'apipi'i fa'apipi'i, axles tua, tootoo feso'ota'i ma kilipa puna e mamafa le uta.
