Abstract: The present invention relates to an Fe-based alloy having a composition including 0.5 mass %?C?0.9 mass %, 0.5 mass %?Si?3.0 mass %, 0.1 mass %?Mn?1.0 mass %, 3.0 mass %?Cr?8.0 mass %, and 0.1 mass %?Mo?4.0 mass %, with the balance being Fe and unavoidable impurities, and satisfying the following expression (1) when [M] represents a content of an element M expressed in mass % basis, ?3.0<[Si]?(5[C]+2[Mn])<?0.5 (1).

Abstract: The present invention provides a plate-shaped member holding system, which stably holds a plate-shaped member without damage during transportation. The plate-shaped member holding system includes a holder for holding a glass sheet as a plate-shaped member and a fixing member engageable with the holder. The holder includes a pair of retainers for clamping the plate-shaped member from both sides of a front side and a rear side thereof, a pair of supports for supporting the retainers, and a coupler for coupling the paired supports. When the holder is engaged with an engagement recess formed in the fixing member with the plate-shaped member being disposed between the paired supports, the holder utilizes the weight of the plate-shaped member to generate pressing forces in directions to bring the paired retainers much closer to each other so as to firmly clamp and stably holds the plate-shaped member by the paired retainers.
