Title (EN) A STEEL, A WELDING CONSUMABLE AND A CAST STEEL PRODUCT
(FR) ACIER, CONSOMMABLE DE SOUDAGE ET PRODUIT EN ACIER COULÉ
Abstract:
(EN) A steel including, in mass %: 0.09 to 0.14% carbon; 0.20 to 0.50% silicon; 1.4% or less manganese; 0.045% or less sulphur; 0.04% or less phosphorus; 0.23 to 0.5% nickel; 0.5% or less chromium; 0.3% or less copper; 0.2% or less molybdenum; 0.020% or less niobium; 0.03% or less vanadium; the balance being iron and incidental impurities, wherein, at least one of conditions (i)-(iii) is satisfied: (i) silicon between 0.20 and 0.45%, manganese plus nickel greater than or equal to 1.5%, carbon multiplied by niobium less than or equal to 0.0015%, and sulphur less than or equal to 0.007%; (ii) three of the quantities of silicon, manganese plus nickel, carbon multiplied by niobium, and sulphur fall within the conditions of (i) and the fourth quantity of silicon, manganese plus nickel, carbon multiplied by niobium, and sulphur not falling within condition (i) falls within a respective condition (a)-(d): (a) niobium multiplied by carbon is less than or equal to 0.0022%; (b) manganese plus nickel is greater than or equal to 1.35%; (c) silicon is less than or equal to 0.50%; and (d) sulphur is less than or equal to 0.007%; or (iii) silicon is between 0.25 to 0.33% and two of the quantities of manganese plus nickel, carbon multiplied by niobium, and sulphur fall within the conditions of (i) and the third quantity of manganese plus nickel, carbon multiplied by niobium and sulphur not falling within condition (i) falls within a respective condition (e)-(g): (e) niobium multiplied by carbon is less than or equal to 0.0022%; (f) manganese plus nickel is greater than or equal to 1.35%; and (g) sulphur is less than or equal to 0.009%.
(FR) L'invention concerne un acier qui comprend, en % en masse : de 0,09 à 0,14 % de carbone ; de 0,20 à 0,50 % de silicium ; 1,4 % ou moins de manganèse ; 0,045 % ou moins de soufre ; 0,04 % ou moins de phosphore ; de 0,23 à 0,5 % de nickel ; 0,5 % ou moins de chrome; 0,3 % ou moins de cuivre ; 0,2 % ou moins de molybdène ; 0,020 % ou moins de niobium ; 0,03 % ou moins de vanadium ; le complément étant du fer et des impuretés fortuites, au moins une des conditions (i) à (iii) étant satisfaite : (i) silicium compris entre 0,20 et 0,45 %, manganèse plus nickel supérieur ou égal à 1,5 %, carbone multiplié par niobium inférieur ou égal à 0,0015 %, et soufre inférieur ou égal à 0,007 % ; (ii) trois quantités parmi silicium, manganèse plus nickel, carbone multiplié par niobium et soufre répondent aux conditions de (i) et la quatrième quantité parmi silicium, manganèse plus nickel, carbone multiplié par niobium et soufre ne satisfaisant pas à la condition (i) satisfait à une condition respective (a) à (d) : (a) niobium multiplié par carbone est inférieur ou égal à 0,0022 % ; (b) manganèse plus nickel est supérieur ou égal à 1,35 % ; (c) silicium est inférieur ou égal à 0,50 % ; et (d) soufre est inférieur ou égal à 0,007 % ; ou (iii) silicium est compris entre 0,25 et 0,33 % et deux quantités parmi manganèse plus nickel, carbone multiplié par niobium, et soufre satisfont aux conditions de (i) et la troisième quantité parmi manganèse plus nickel, carbone multiplié par niobium et soufre ne satisfaisant pas à la condition (i) satisfait à une condition respective (e) à (g) : (e) niobium multiplié par carbone est inférieur ou égal à 0,0022 % ; (f) manganèse plus nickel est supérieur ou égal à 1,35 % ; et (g) soufre est inférieur ou égal à 0,009 %.
