焊接、闪光控制、低碳钢钢管 经正火处理适用于弯曲、双胀形、胀边、成型和钎焊（稳定版：2025年6月

[中文适用范围]： 本SAE标准涵盖标准化的电阻焊、闪光控制、单层低碳钢压力管，适用于作为压力管路及其他需要弯曲、双胀、成形、钎焊等工艺的管材应用。按本规范生产的材料不适用于单胀接应用，因为内径（ID）焊点或削边区域可能造成泄漏路径。若使用该材料进行单胀接应用，生产商和采购方需事先协商并明确风险责任。本规范还包括SAE J356 Type-A管材。SAE J356与SAE J356 Type-A的机械性能和性能要求相同。SAE J356或SAE J356 Type-A的标识区分了盘卷材料和直管材料的制造差异。该管材的标称参考工作压力见ISO 10763（公制管材）和SAE J1065（英制管材）。SAE J356管材以直管形式生产，并经过二次热处理。SAE J356 Type-A管材在线热处理以消除应力，并以盘卷形式生产。为实现全球市场标准化，确保企业在全球市场中保持竞争力，本标准旨在推动采用公制管材尺寸，这将带来以下好处：建立一个全球统一的系统；引导用户使用推荐系统；降低复杂性；消除库存重复。 [外文原描述]： This SAE Standard covers normalized electric-resistance welded flash-controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading, forming, 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. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of SAE J356 and SAE J356 Type-A are the same. The SAE J356 or SAE J356 Type-A designation define unique manufacturing differences between coiled and straight material. Nominal reference working pressures for this tubing are listed in ISO 10763 for metric tubing, and SAE J1065 for inch tubing. SAE J356 is produced in straight lengths that undergo a secondary heat treat operation. SAE J356 Type-A tubing is heat treated in-line to relieve stresses, and is produced in coil form.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 preferred system - Reduce complexity - Eliminate inventory duplications
