| description | Un acero para muelles de alta resistencia que contiene: C: 0,15-0,33 % (significa % en masa, en adelante lo mismo); Si: 1-3,5 %; Mn: 0,20-2,0 %; y que contiene: al menos un elemento seleccionado de un grupo que consiste en Ti: 0,005-0,10 %, Nb: 0,005-0,05 % y V: 0,05-0,25 %; Cr: 0,05-1,20 %; P: 0,030 % o menos; S: 0,02 % o menos; y que contiene además opcionalmente Ni: 0,05-2 % y Cu: 0,05-0,50 %; y que contiene además opcionalmente B: 0,005 % o menos y/o Mo: 0,60 % o menos siendo el resto hierro o impurezas inevitables, donde un carbono equivalente Ceq1 expresado según la fórmula (1) a continuación es 0,55 o menos. Ceq1=[C]+0,108 x [Si]-0,067 x [Mn]+0,024 x [Cr]-0,05 x [Ni]+0,074 x [V]...(1) (En la fórmula (1), cada símbolo entre corchetes representa el contenido (% en masa) del elemento correspondiente.)
Provided is a spring steel that contains 0.15-0.40% carbon, 1-3.5% silicon, 0.20-2.0% manganese, 0.05-1.20% chromium, at most 0.030% phosphorus, at most 0.02% sulfur, and at least one of the following: 0.005-0.10% titanium, 0.005-0.05% niobium, and at most 0.25% vanadium. The remainder of said spring steel comprises iron and unavoidable impurities. The carbon equivalent (Ceq 1 ) of the provided spring steel, as calculated by formula (1), is at most 0.55. Ceq 1 = C + 0.108 × Si - 0.067 × Mn + 0.024 × Cr - 0.05 × Ni + 0.074 × V (In the formula (1), each symbol in brackets represents the content (mass%) of the corresponding element.) |
