Tlhaloso:

Q460 ke tšepe e matla e tlase ea alloy. Q e emela matla a tšepe, 460 e emela 460 MPa, mega ke matla a 6 a 10,

'me Pa ke karolo ea khatello ea Pascal. Q460 e bolela hore deformation polasetiki ea tšepe e tla etsahala feela ha matla a tšepe

e fihla ho 460 MPa, ke hore, ha matla a ka ntle a lokolloa, tšepe e ka boloka sebōpeho sa matla feela 'me e ke ke ea khutla.

ho sebopeho sa yona sa pele. Matla ana a maholo ho feta a tšepe e tloaelehileng.

Motheong oa ho netefatsa ho lekana ha khabone e tlase, Q460 e eketsa ka nepo litaba tsa likarolo tsa microalloying. Welding e ntle

ts'ebetso e hloka k'habone e lekanang le tšepe e tlase, 'me keketseho ea likaroloana tsa microalloying e eketsa matla a tšepe.

ha e ntse e eketsa k'habone e lekanang le tšepe. Ka lehlohonolo, k'habone e ekelitsoeng e lekanang le eona e nyane haholo, ka hona e ke ke ea ama

ho cheseha ha tšepe.
