液体窒素ハンドリングシステムにおける極低温 ウェーブスプリング 用途における A286 ステンレス鋼の利点を分析します。

A286 is an iron-base superalloy that maintains high strength and, crucially, high toughness at cryogenic temperatures down to -196°C (77K). Unlike standard carbon steels or some martensitic stainless steels which undergo a ductile-to-brittle transition (DBT), A286 remains austenitic. Its coefficient of thermal expansion is also relatively stable. In cryog...
