Product Code:SAE J2833
Title:Welded and Cold-Drawn, High Strength (690 MPa Tensile Strength) Low Alloy Steel Hydraulic Tubing, Stress Relieved Annealed for Bending and Flaring
Issuing Committee:Metallic Tubing Committee
Scope:This specification covers sub-critically annealed electric resistance welded and cold-drawn singlewall high strength low alloy steel tubing intended for use in hydraulic pressure lines and in other applications requiring tubing of a quality suitable for bending, flaring, cold forming, welding and brazing.The grade of material produced to this specification is of micro-alloy content and is considerably stronger and intended to service higher pressure applications using thinner walls than like sizes of the grades of material specified in SAE J525, SAE J2467 and SAE J2614. Due to the alloy content of the material, the forming characteristics of the finished tube are equal to or better, when compared to SAE J525, SAE J2467 and SAE J2614. Nominal reference working pressures for this tubing are listed in SAE J1065.Caution: When brazing or welding is used as a tube end joining method, the structural integrity of the tube material can potentially be compromised due to the degradation of the areas affected by the thermal effect applied to the tubing; therefore, the SAE J1065 nominal reference working pressures may not be applicable.Brazed and/or welded tube assembly configurations made to specific geometry and components bill of material in association with this material, may require qualification testing in accordance with SAE J2658 Metallic Tube Conductor Assemblies for Fluid Power and General Use?Test Methods for Hydraulic Fluid Power Metallic Tube Assemblies. Cold forming the tube end configurations avoids this systemic testing by not compromising the tube material structural integrity.【英文标准名称】:Guidefortheprocurementofpowerstationequipment-Electricalequipment-Generators
