steel for cryogenic useとは 意味・読み方・使い方

To provide a nonheat-treated steel which has suitable toughness within a use temperature range, and is easily fractured and separated not only in the conventional low temperature region including a cryogenic region for liquid nitrogen cooling or the like required by the object to be fractured, but also in an inexpensively reachable low temperature region, and to provide an engaged member fractured and separated at low temperatures.例文帳に追加

使用温度範囲内では適度な靱性を有し、従来の低温で破断するものが必要とした液体窒素冷却等による極低温領域はもちろんのこと、安価に到達可能な低温領域で破断分離が容易な非調質鋼及び低温で破断分離する勘合部材を提供すること。 - 特許庁
