Abstract | The purpose of the present invention is to provide a stainless steel powder that can be used to produce a stainless steel member having high strength, excellent low-temperature toughness, and excellent corrosion resistance in a high-temperature, harsh corrosive environment including carbon dioxide (CO2) and chlorine ions (Cl-) or in an environment including hydrogen sulfide (H2S). The stainless steel powder has a specific composition, a D50 particle diameter, which is the median diameter located at the 50th percentile of the mass cumulative distribution, of 10-200 μm, and an apparent density of 3.5-5.0 mg/m3.
L'objectif de la présente invention est de fournir une poudre d'acier inoxydable qui peut être utilisée pour produire un élément en acier inoxydable ayant une robustesse élevée, une excellente ténacité à basse température, et une excellente résistance à la corrosion dans un environnement corrosif agressif à haute température comprenant du dioxyde de carbone (CO2) et des ions chlore (Cl-) ou dans un environnement comprenant du sulfure d'hydrogène (H2S). La poudre d'acier inoxydable possède une composition spécifique, un diamètre particulaire D50, qui est le diamètre médian situé au 50ème percentile de la distribution massique cumulée, de 10 à 200 µm, et une densité apparente de 3,5 à 5,0 mg/m3.
本発明は、炭酸ガス(CO2)および塩素イオン(Cl-)を含む高温の厳しい腐食環境下や、硫化水素(H2S)を含む環境下等において、高強度と、優れた低温靭性と、優れた耐食性とを有するステンレス鋼部材を製造することができるステンレス鋼粉末を提供することを目的とする。特定の組成を有し、質量累積分布の50%に位置するメジアン径である粒径D50が10~200μmであり、見掛密度が3.5~5.0Mg/m3であるステンレス鋼粉末。 |
