Q460 o se u'amea maualuga-maualalo maualalo. Q o loʻo faʻatusalia le malosi o uʻamea, 460 faʻatusa 460 MPa, mega o le 6th mana o le 10,

ma Pa o le vaega mamafa o Pascal. Q460 o lona uiga o le palasitika deformation o le sila na o le a tupu pe a le malosi o le sila

e oʻo atu i le 460 MPa, o lona uiga, pe a tuʻuina atu le malosi i fafo, e mafai e le sila ona faʻatumauina le foliga o le malosi ma e le mafai ona toe foʻi mai.

i lona foliga muamua. O lenei malosi e sili atu nai lo le sila masani.

I luga o le faʻavae o le faʻamautinoaina o le maualalo o le kaponi tutusa, Q460 faʻatuputeleina talafeagai le anotusi o elemene microalloying. Lelei uelo

faʻatinoga e manaʻomia ai le maualalo o le carbon e tutusa ma le sila, ma o le faʻateleina o elemene microalloying e faʻateleina ai le malosi o le sila.

a'o fa'ateleina fo'i le kaponi tutusa o le sila. O le mea e lelei ai, o le faʻaopoopo tutusa o le carbon e laʻititi tele, o lea e le afaina ai le

weldability o le uamea.
