本SAE标准涵盖了标准化电阻焊闪光控制单壁SAE 1021碳钢压力管，用于压力管道和其他要求管道质量适合弯曲、双扩口、冷成型、焊接和钎焊的应用。根据本规范生产的材料不适用于单火炬应用，因为内径（ID）焊道或斜切区域可能导致泄漏路径。 在单火炬应用中使用该材料时的风险承担应由生产商和买方之间的协议确定。根据本规范生产的材料等级的碳和锰含量高于SAE J356中规定的材料等级，且用于比SAE J356同等尺寸更高的压力应用。由于碳和锰含量较高，与SAE J356产品相比，成品管的成形特性降低。 在指定按照本规范生产的材料时，应特别注意成品组件的整体成型要求。参考SAE J2551-1，了解与该材料相关的其他设计和制造指南。ISO 10763和SAE J1065中列出了该材料的标称工作压力。如有要求，鉴定测试应符合ISO 19879的要求。为了在全球市场内实现标准化，并确保公司在国际市场上保持竞争力，我们打算将其转换为公制管尺寸，这将: 通向一个全球体系。引导用户使用首选系统。降低复杂性。消除库存重复。

This SAE Standard covers normalized electric resistance welded flash controlled single-wall, SAE 1021 carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, cold forming, welding, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path caused by the inside diameter (ID) weld bead or scarfed region. Assumption of risks when using this material for single flare applications shall be defined by agreement between the producer and purchaser.The grade of material produced to this specification is higher in carbon and manganese content than the grade of material specified in SAE J356 and is intended to service higher pressure applications than equivalent sizes of SAE J356. Due to the higher carbon and manganese content, the forming characteristics of the finished tube are diminished versus the SAE J356 product. Special attention to the overall forming requirements of the finished assembly shall be taken into consideration when specifying material produced to this specification. Refer to SAE J2551-1 for additional design and fabrication guidance associated with this material. Nominal working pressures for this material are listed in ISO 10763 and SAE J1065. When required, qualitication testing shall be in accordance with ISO 19879.In an effort to standardize within a global marketplace and ensure that companies can remain competitive in an international market, it is the intent to convert to metric tube sizes which will:Lead to one global system.Guide users to a preferred system.Reduce complexity.Eliminate inventory duplications.
