P265GH Umuvuduko w'icyuma Icyuma

P265GH Icyuma - Gushyushya Kurwanya & Non-Alloy

P265GH ni iki?
Icyiciro P265GH nicyuma gishyuha cyumuvuduko wa Vessel Steel yasobanuwe muri sisitemu ya EN 10028. Nicyuma kitavanze. Ibikoresho byateguwe kubushyuhe bwo hejuru. Kubwibyo ikoreshwa cyane mubushyuhe bwo hejuru murwego rwa peteroli na gaze, inganda zitunganya imiti ninganda za peteroli.

Nibintu nyamukuru bihimbira amashyiga hamwe nibikoresho byotswa igitutu. Nibisanzwe mukubika ubushyuhe bwa 890 kugeza 950 ° C udafashe; gushyushya binyujijwe mu bunini bw'isahani.

EN 10028 ni iki?
P265GH yamenyekanye mubisanzwe EN 10028. Nibipimo byiburayi byibikoresho bya "Flat ibicuruzwa bikozwe mubyuma bigamije igitutu". Byongeye kandi ibisanzwe bikubiyemo "Non-alloy and alloy ibyuma hamwe nubushyuhe bwihariye bwo hejuru". Ibipimo byasohotse mu mwaka wa 2009.

Kuki P265GH bita A516 icyiciro cya 60 Icyuma?
P265GH nigisobanuro kivanze mubipimo byuburayi, byitwa kandi A516 icyiciro cya 60 muri ASME / ASTM. Ababikora benshi bavuga ko bubahiriza ibisobanuro byombi bya EN 10028 na ASME / ibikoresho bya ASTM A516 icyiciro cya 60 ibyuma.

Amagambo
GH - nibyiza gukoreshwa mubushyuhe bwo hejuru bwakazi
NH - kuri serivisi yubushyuhe buringaniye
NL1 - nibyiza gukoreshwa mubushyuhe buke
NL2 - nibyiza gukoreshwa cyane cyane ubushyuhe buke
