Q355B pā kila

ʻO ka pā kila Q355B he pā kila ikaika kiʻekiʻe. ʻO ka pā kila Q355B he hana mechanical maikaʻi loa, hana haʻahaʻa haʻahaʻa, a me ka plasticity maikaʻi a me ka weldability. Hoʻohana ʻia ke kila Q355B no ka hana ʻana i ka ipu hao, pahu aila, kaʻa, crane, mīkini mining, mana mana, alahaka, etc.

ʻO ka hui kemika o ka pā kila Q355B:
C≤0.24, Si≤0.55, Mn≤1.6, P≤0.035, S≤0.035, Ni≤0.3; Cr≤0.3, N≤0.0012

Nā waiwai mīkini o ka pā kila Q355B:
Hua ikaika≥355, ikaika tensile: 470-630, Akv≥34.

Hoʻohana nui ʻia ka pā kila Q355B i ka ʻenekinia, nā mīkini mining, nā alahaka, nā kaʻa, nā moku, ke kūkulu ʻana, nā moku kaomi, nā mea hana kūikawā, etc.
