    Abstract: A vehicle wheel is made of cast steel and has a thickness of steel small with respect to its diameter. The steel has a carbon content within the range of 0.16 to 0.70 percent, a manganese content within the range of 0 to 1.60 percent, and a silicon content within the range of 0 to 1.00 percent. The tensile strength of the steel is within the range of 40 kg/mm2 to 80 kg/mm2, and the steel is hardened through about 10 to 20 percent of its thickness. The thickness of the steel is increased in the rim flange as compared to the rim base, and the axially outer wall of the rim flange is inclined with respect to the rim axis. Any shrink marks that may appear in the cast steel are concentrated in the thickened portion of the rim flange.

    Abstract translation: 车轮由铸钢制成，其厚度相对于其直径小。 钢的碳含量在0.16〜0.70％的范围内，锰含量在0〜1.60％的范围内，硅含量在0〜1.00％的范围内。 钢的拉伸强度在40kg / mm2至80kg / mm2的范围内，钢的硬度约为其厚度的10至20％。 与轮辋底座相比，轮辋凸缘中的钢的厚度增加，并且轮辋凸缘的轴向外壁相对于轮辋轴线倾斜。 任何可能出现在铸钢中的收缩痕集中在轮辋凸缘的加厚部分。
