S690QL pā kila ikaika kiʻekiʻe

Ma muli o ke ʻano o ka ikaika kiʻekiʻe, me ka hoʻohana ʻana iā S690QL e hoʻolaha i nā hale i hoʻolālā ʻia me ka hoʻonui ʻia o ka uku uku a me ka pono o ka ikehu.
Hōʻike ʻia nā kikoʻī ʻenehana o S690QL ma lalo nei.
S690QL - Hoʻokohu Papa
ʻO ka papa inoa o S690QL penei:
S = Ke kila kila
690 = ikaika hua liʻiliʻi (MPa)
Q = Ka hoʻopau ʻana a me ka hoʻopaʻa ʻana
L = Haʻahaʻa notch toughness hoao ana wela

S690QL - Hoʻohui Kemika
Hāʻawi ʻia ka haku mele S690QL ma ka papa ma lalo.
