ES-1057标准中英对照简介.doc

PURPOSE 目的 The purpose of this material standard is to provide a comprehensive hot forged steel specification that will allow a cost-effective end product to be produced. Any supplier suggestions to improve product cost will always be evaluated. This standard is intended to supplement any and all requirements currently specified on the applicable engineering detail drawing. All references to steel and properties apply to the finished forged product unless otherwise noted. 这种材料标准的目的是提供一种全面的热锻造钢的规范，将允许生产具有成本效益的最终产品。 供应商提出的，以提高产品的性价比的任何建议会一直进行评估。该标准旨在补充任何及所有要 求，目前适用的工程详图规定。除非另有说明，钢和属性的所有引用适用于锻造品。 RESPONSIBILITY 责任 The Director of Engineering is responsible to assure that this specification accurately reflects the up-to-date material standard. The Director of Purchasing is responsible to assure that the appropriate specification is forwarded to the vendor concerned. Plant managers are responsible to assure that the specification is followed at the local level. 工程总监负责确保本规范准确地反映必威体育精装版的材料标准。采购的主任确保适当的规范转发给有关的供应商。工厂经理有责任确保规范符合地方标准。 SPECIFICATIONS 规范 Application 应用 The steel will be used for on and off highway trailer axle spindles and torsion arms. Typically, the spindles will be fixtured and then arc welded by rotating the spindle coaxially with the axle tube. The torsion arms will have spindle and inner bar pressed into them, and then the assembly is welded together. During their service life, both the spindles and the torsion arms will experience bending, impact and/or torsional stresses. 该钢适用于高速路/普通路段拖车轮轴和扭力臂。典型的，轴将被夹具固定，然后通过电弧与车轴管同轴旋转主轴焊接。通常来说，主轴会被压入，然后将组件焊接在一起。在其使用寿命内，主轴经受弯曲，冲击和/或扭转应力。 Properties 性能 High toughness, low notch sensitivity, good torsional stiffness, good weldability, relatively high strength, and high fatigue resistance are all desirable properties. The steel stock shall be hot rolled, special quality, manufactured in compliance with the applicable sections of ASTM A-434 standard of the latest issue, subject to supplementary requirements
