P265GH Ke kila - Heat Resistant & Non-Alloy

He aha ka P265GH?
ʻO ka papa P265GH ka Heat Resistant Pressure Vessel Steels i wehewehe ʻia ma ka ʻōnaehana EN 10028. He kila non-alloy. Hoʻolālā ʻia ka mea no nā noi wela kiʻekiʻe. No laila, hoʻohana nui ʻia ia i nā noi wela kiʻekiʻe i ka ʻāpana aila a me ke kinoea, nā ʻoihana hana kemika a me nā ʻāpana petrochemical.

He mea hana nui ia o nā paila a me nā moku kaomi. Hoʻomaʻamaʻa ʻia ia e ka mālama ʻana i kahi mahana o 890 a 950 ° C me ka ʻole e paʻa; hele ka hoʻomehana ma ka mānoanoa o ka pā.

He aha ka EN 10028?
Ua ʻike ʻia ʻo P265GH i ka maʻamau EN 10028. He mea maʻamau ʻEulopa no "nā huahana Flat i hana ʻia i nā kila no nā kumu kaomi". Hoʻopili ʻia ka maʻamau "Non-alloy and alloy steels me nā waiwai wela kiʻekiʻe". Ua paʻi ʻia ka maʻamau i ka makahiki 2009.

No ke aha ʻo P265GH i kapa ʻia ʻo A516 grade 60 Steel?
ʻO P265GH ka mea i koho ʻia i ka maʻamau ʻEulopa, i kapa ʻia ʻo A516 grade 60 ma nā kūlana ASME / ASTM. Manaʻo nā mea hana he nui e hoʻokō i nā kikoʻī ʻelua o EN 10028 a me ASME / ASTM material A516 grade 60 steel.
