P265GH Steel - Okpomọkụ na-eguzogide & Na-abụghị Alloy

Kedu ihe bụ P265GH?
Ọkwa P265GH bụ ụgbọ mmiri na-eguzogide okpomọkụ akọwapụtara na sistemụ EN 10028. Ọ bụ ígwè na-abụghị alloy. Emebere ihe a maka ngwa okpomọkụ dị elu. Ya mere, a na-ejikarị ya na ngwa okpomọkụ dị elu na mpaghara mmanụ na gas, ụlọ ọrụ nhazi kemịkalụ na mpaghara petrochemical.

Ọ bụ isi ihe na-emepụta ihe ọkụkụ na arịa ndị nrụgide. A na-edozi ya site na idobe ya na okpomọkụ nke 890 ruo 950 Celsius na-enweghị njide; A na-agafe kpo oku site na ọkpụrụkpụ nke efere ahụ.

Kedu ihe bụ EN 10028?
Achọpụtara P265GH na ọkọlọtọ EN 10028. Ọ bụ ụkpụrụ ihe eji eme ihe na Europe maka "Ngwaahịa Flat mere nke nchara maka ebumnuche nrụgide". Ọzọkwa ọkọlọtọ na-ekpuchi "Ndị na-abụghị alloy na alloy steels na kpọmkwem elu okpomọkụ Njirimara". E bipụtara ọkọlọtọ n'afọ 2009.

Gịnị kpatara P265GH ji kpọọ A516 ọkwa 60 ígwè?
P265GH bụ alloy nhọpụta na ọkọlọtọ European, nke akpọrọ A516 grade 60 na ụkpụrụ ASME / ASTM. Ọtụtụ ndị na-emepụta na-ekwu na ha na-akwado ma nkọwapụta nke EN 10028 na ASME / ASTM ihe A516 ọkwa 60 ígwè.
