ʻO nā mea kanu lāʻau austetitic (304L, 316L) ʻaʻohe ductive-to-brittle consled mahana (Dbtt) Nā luna -270 ° C, Ke hoʻomau nei i ka ductility ma nā wela cryogen.

Ua liloʻo Carbon Steel i Beritania ma ≤ -40 ° C, e hana ana i ka shattering.

Pehea e pale aku ai nā mea kūʻai aku crisogenic?

Hoʻonui i nā bonnet i hoʻonui i ka mamao ma waena o ka wai cryogen a me ka mea hana, Ke mālama nei i ka mea hana ma keʻano ambied.

ʻO kekahi mau hoʻolālā pūhaka e hoʻopili ai i nā paʻi kiʻiʻoniʻoni a iʻole ka hoʻoweliweliʻana i ka bonnet e pale ai i ka hale kūkulu hale.

He aha ke ola lawelawe o kahi varygenic vary?

Nā Visogen Wistogen Cryogen (316L kino, Nā Hana Ffkm) E loaʻa i kahi ola lawelawe o 10-20 mau makahiki ma LNG lawelawe.

I nā noi noi (Lh₂, AerERPPACE), ʻO ke ola lawelawe he 5-10 mau makahiki ma muli o ke kaumaha kiʻekiʻe.
