查看样本合金摘要数据表（PDF）自1952年以来，合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。以图表、图表和表格为特色，这些表格给出了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。SAE 4147是一种中碳低合金钢，具有较高的淬透性和良好的耐磨性、疲劳性和抗冲击性。建议在中重度工况下使用。尽管SAE 4147名义上为油硬化等级，但如果采取适当的预防措施，将淬火过程中开裂的危险降至最低，则SAE 4147可以水硬化。在850℃范围内回火时，回火脆性的发展趋势相对较低- 1100 F.典型应用包括齿轮、轴系、机床零件、离合器零件和连杆。

View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.SAE 4147 is a medium-carbon low-alloy steel with relatively high hardenability and good resistance to abrasion, fatigue and impact. It is recommended for moderately severe service. Although nominally an oil-hardening grade, SAE 4147 may be water hardened if suitable precautions are taken to minimize the danger of cracking during quenching. It has a relatively low tendency for the development of temper embrittlement during tempering in the range 850-1100 F. Typical applications comprise gears, shafting, machine-tool parts, clutch parts and connecting rods.
