Title (EN) STEEL FOR MOLDS AND MOLDING TOOL
(FR) ACIER POUR MOULES ET OUTIL DE MOULAGE
(JA) 金型用鋼及び成形具
Abstract:
(EN) This steel for molds contains 0.38 mass% < C < 0.55 mass%, 0.003 mass% ≤ Si < 0.300 mass%, 0.70 mass% < Mn < 1.80 mass%, 0.80 mass% ≤ Cr < 2.00 mass%, 0.003 mass% ≤ Cu < 1.200 mass%, 0.003 mass% ≤ Ni < 1.380 mass%, 0.500 mass% < Mo < 3.500 mass%, 0.55 mass% < V < 1.20 mass% and 0.0002 mass% ≤ N < 0.1200 mass%, with the balance made up of Fe and unavoidable impurities; and this steel for molds satisfies 0.550 mass% < (Cu + Ni + Mo) < 3.600 mass%. A molding tool according to the present invention comprises a mold and/or a mold component that is formed of this steel for molds.
(FR) L'invention concerne un acier pour des moules qui contient 0,38 % en masse < C < 0,55 % en masse, 0,003 % en masse ≤ Si < 0,300 % en masse, 0,70 % en masse < Mn < 1,80 % en masse, 0,80 % en masse ≤ Cr < 2,00 % en masse, 0,003 % en masse ≤ Cu < 1,200 % en masse, 0,003 % en masse ≤ Ni < 1,380 % en masse, 0,500 % en masse < Mo < 3,500 % en masse, 0,55 % en masse < V < 1,20 % en masse et 0,0002 % en masse ≤ N < 0,1200 % en masse, le reste étant constitué de Fe et d'impuretés inévitables, et cet acier pour moules satisfait à la relation 0,550 % en masse < (Cu + Ni + Mo) < 3,600 % en masse. La présente invention concerne également un outil de moulage qui comprend un moule et/ou un élément de moule qui est formé à partir de cet acier pour des moules.
(JA) 本発明の金型用鋼は、0.38<C<0.55mass%、0.003≦Si<0.300mass%、0.70<Mn<1.80mass%、0.80≦Cr<2.00mass%、0.003≦Cu<1.200mass%、0.003≦Ni<1.380mass%、0.500<Mo<3.500mass%、0.55<V<1.20mass%、及び、0.0002≦N<0.1200mass%を含み、残部がFe及び不可避的不純物からなり、0.550<Cu+Ni+Mo<3.600mass%を満たし、本発明の成形具は、このような金型用鋼からなる金型及び/又は金型部品を含む。
