OVERHEATING-INSENSITIVE FINE GRAINED ALLOY STEEL FOR USE IN DOUBLE HIGH-FREQUENCY HEAT TREATMENT AND METHOD OF MANUFACTURING THE SAME |
| 摘要 |
A fine-grained alloy steel includes iron (Fe) as a main component, and 0.40 to 0.55% by weight of carbon (C), 0.20 to 0.40% by weight of silicon (Si), 0.8 to 1.0% by weight of manganese (Mn), 0.8 to 1.2% by weight of chromium (Cr), 0.045% by weight of aluminum (Al), and inevitable impurities, based on a total weight of the alloy steel. |
