A302 GR.D ʻO ka paila a me ka ipu hao paʻi

ʻO ka paila kila A302 Grade D he ʻano hao hao me Manganese, Molybdenum a me nickel. A302 Grade D kahi mea ʻoi aku ke kiʻekiʻe o ka Nickel i ka ʻōwili ʻana ma mua o ka Boiler steel plate A302 Grade C. Pressure moku kila paʻa nona ka waiwai like ma ka waiwai mechanical e like me ʻO A302 Grade B a me A302 Grade C, hāʻawi i ka ikaika ma luna o 345 Mpa, a me ka ikaika tensile i loko o 550-690 Mpa.Gnee steel makemake e hāʻawi i ka MTC ma lalo o ke ʻano EN 10204 3.1 a i ʻole EN 10204 3.2 me nā ʻaoʻao ʻekolu.

Koi ʻenehana a me nā lawelawe hou aku:
♦  Hoʻāʻo hoʻopaʻapaʻa kiʻekiʻe
♦  E hoʻāʻo e pili ana i ka wela haʻahaʻa
♦  Hoʻohana maʻamau no nā papa mānoanoa ma luna o 40mm
♦  Hoʻomaʻamaʻa ʻia me ka wela ma hope o ka welo ʻana (PWHT)
♦  Ke holo nei ma lalo o NACE MR-0175 (HIC+SSCC)
♦  Ua hoʻopuka ʻia ka palapala hōʻike hoʻāʻo ʻo Oginal Mill ma lalo o EN 10204 FORMAT 3.1/3.2
♦  Paʻi ʻana a me ka pena, ʻoki ʻana a me ka wiliwili e like me nā koi o ka mea hoʻohana hope.
