ASTM A515/A515M maitai

Ko nga pereti i raro i tenei whakaritenga e waatea ana i roto i nga reanga e toru he rereke nga taumata kaha e whai ake nei:

Kōeke U.S. [SI]	Te Kaha Tana, ksi [MPa]
60 [415]	60–80 [415–550]
65 [450]	65–85 [450–585]
70 [485]	70–90 [485–620]

Ko te tino matotoru o nga papa he iti noa na te kaha o te hanganga ki te whakatutuki i nga whakaritenga taonga miihini kua tohua; engari, ko te tikanga o naianei ka whakawhäiti i te tino matotoru o nga pereti kua oti i raro i tenei whakaritenga e whai ake nei:

Kōeke U.S. [SI]	Te Matotoru Morahi, in. [mm]
60 [415]	8 [200]
65 [450]	8 [200]
70 [485]	8 [200]
