NM400 / NM 450 wọ resistance irin awo
NM450 jẹ awo yiya agbara giga.
Orukọ: N jẹ fun resistance (nai), M jẹ lẹta pinyin akọkọ ti awọn ohun kikọ Kannada meji fun lilọ (mo),
ati 450 duro ni apapọ Brinell líle ti yi irin awo
Itọju igbona: iwọn otutu giga, quenching + tempering (quenching ati tempering)
Ohun elo: NM450 yiya-sooro irin awo ni o gbajumo ni lilo ninu iwakusa ẹrọ, edu iwakusa ẹrọ,
Ẹrọ aabo ayika, ẹrọ ikole, ati bẹbẹ lọ, ati pe a tun lo nigbagbogbo bi agbara-giga
irin igbekale pẹlu agbara ikore ≥850MPa.
iṣẹ: O ti wa ni o kun lati pese aabo ni awọn igba tabi awọn ẹya ara ti o nilo yiya resistance, ki awọn aye ti
ohun elo naa gun, akoko itọju ti o fa nipasẹ itọju ti dinku, ati idoko-owo olu
ni ibamu dinku.
Iṣe: Ikore jẹ diẹ sii ju 950, ati agbara fifẹ jẹ 1180.
NM450 ni ibamu si awọn ipele ajeji ati awọn onipò JFE:NK-EH450/HARDOX450/DILLDUR:450V
