A steel material is useful for producing the upper part of engine pistons with
high wear, corrosion and heat resistance. This steel has
the following composition (in % by weight): 1.20 to 1.50 Mn; 0.50 to 0.80 Si;
0.35 to 0.40 C; 0.10 to 0.50 Mn; 0.08 to 0.13 V; 0.010 to
0.065 S; 0.015 to 0.050 Al; <= 0.035 P, the remainder being iron and
production impurities.
Ce matériau d'acier est utile pour produire les parties supérieures de pistons de moteurs présentant une haute résistance à l'usure, à la corrosion et à la chaleur. Cet acier a la composition suivante, en pourcentages en poids: 1,20 à 1,50 de Mn; 0,50 à 0,80 de Si; 0,35 à 0,40 de C; 0,10 à 0,50 de Mo; 0,08 à 0,13 de V; 0,010 à 0,065 de S; 0,015 à 0,050 d'Al; </= 0,035 de P; le pourcentage restant étant constitué de fer et d'impuretés découlant de la production.
