P460NH Paʻi Paʻi Paʻa Paʻa

ʻO P460NH, i kapa ʻia no ka loaʻa ʻana o ka ikaika haʻahaʻa haʻahaʻa o 460 MPa, he kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe o ka ipu hao no ka hoʻohana ʻana i ka paila a me ka hana ipu kaomi. He kila palaoa normalized me ka maikaʻi weldability hiʻona.

Aia nā ʻano papa ʻē aʻe…
NL1 - kūpono no ka hoʻohana ʻana i nā mahana haʻahaʻa
NL2 - kūpono no ka hoʻohana ʻana i nā mahana haʻahaʻa

Hoʻohana pū ʻia ʻo P460NH i nā noi kinoea ʻawaʻawa kahi e hoʻāʻo ʻia ai ke kila e hoʻāʻo ʻia ʻo HIC e ʻike ai i ka hiki ʻole o nā mea i ka haki ʻana i ka hydrogen.
