hard steel (0.4-0.5C, 0.15~0.25Si,0.5~0.7Mn, <0.05P 和 S); medium-carbon steel (【技】含碳量为0.25% -0.60%的碳素钢，多在调质状态下用于制作机械零件，例如螺栓、螺杆等。: ① Medium-carbon steels are often used where greater strength and toughness are required. 中碳钢常常用于强度和韧性都要求较高的场合。 ②For the medium-carbon steels, mould flux E led a slightly higher heat flux (approximately 6 % higher than fluxes D and F). 对于中碳钢而言，结晶器保护渣 E 导致了稍高的热通量(比保护渣 D 和 F 高约 6%) 。 ③Using the mold flux consumption as a criterion of judging oscillation mark depth, it is expected that the mold fluxes A and B, for the trials with the stainless steel, and powder E, for the trials with the medium carbon steel, would give better results in terms of oscillation mark depth. 使用结晶器保护渣耗量作为判断振痕深度的标准，人们预期不锈钢试验时使用保护渣 A 和 B、 中碳钢试验时使用保护渣 E, 在表达振痕深度方面会给出较好的结果。); medium carbon steel (【技】含碳量为0.25% -0.60%的碳素钢，多在调质状态下用于制作机械零件，例如螺栓、螺杆等。: ① Medium-carbon steels are often used where greater strength and toughness are required. 中碳钢常常用于强度和韧性都要求较高的场合。 ②For the medium-carbon steels, mould flux E led a slightly higher heat flux (approximately 6 % higher than fluxes D and F). 对于中碳钢而言，结晶器保护渣 E 导致了稍高的热通量(比保护渣 D 和 F 高约 6%) 。 ③Using the mold flux consumption as a criterion of judging oscillation mark depth, it is expected that the mold fluxes A and B, for the trials with the stainless steel, and powder E, for the trials with the medium carbon steel, would give better results in terms of oscillation mark depth. 使用结晶器保护渣耗量作为判断振痕深度的标准，人们预期不锈钢试验时使用保护渣 A 和 B、 中碳钢试验时使用保护渣 E, 在表达振痕深度方面会给出较好的结果。); med. s.
