AISI 4140 SCM440 DIN 42CrMo4 1.7225 Faiga Fa'amea Fa'ameamea

AISI 4140 o loʻo faʻamatalaina o se uʻamea uʻamea maualalo o loʻo i ai le 1% Cr-Mo e pei o le faʻamalosia o elemene uʻamea. Faʻatusatusa i le AISI 4130, o loʻo i ai le maualuga o le carbon content ma paleni lelei o le malosi, faigata, abrasion ma le aʻafiaga o le teteʻe ma togafitiga vevela, ae matitiva i le uelo gafatia uiga.AISI 4140 e masani lava ona tuuina atu i tineia ma ita tulaga ma maaa 28-32HRC.
