Product Code:SAE J2435
Title:Welded Flash Controlled, SAE 1021 Carbon Steel Tubing, Normalized for Bending, Double Flaring, and Beading
Issuing Committee:Metallic Tubing Committee
Scope:The 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, beading, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path that would be caused by the ID weld bead.The grade of material produced to this specification is higher in carbon content and manganese content than the grade of material specified in SAE J356. The material produced to this specification is intended to service higher pressure applications than like sizes of SAE J356. Due to the higher carbon and manganese content, however, the forming characteristics of the finished tube is diminished somewhat when compared to SAE J356. Special attention to the overall forming requirements of the finished assembly should be taken into consideration when utilizing material produced to this specification.ion when utilizing material produced to this specification.【英文标准名称】:Switchgear-High-VoltageAirSwitches-RatedControlVoltagesandTheirRanges(AdditiontoTable1);SupplementC37.33A-1990
