Product Description

TORICH SAE J525 Din2391 Carbon ST37.4 E355 Alloy 4140 25CrMo4 Cold Drawn High Precision Hydraulic Seamless Steel Tube 
 Description

This specification covers nominal thickness, seamless, cold-drawn carbon steel tubing intended for use in hydraulic systems and in other similar applications where forming operations require tight radius bending and flaring. The tubes shall be made by the seamless process and shall be cold drawn to size. Heat treatment shall be made to the tube samples after the final cold working operation. Finished tubes shall be free of scale but may have a superficial oxide film on the surfaces. Removal of surface imperfections, such as handling marks, straightening marks, light mandrel and die marks, shallow pits, and scale patterns, will not be required provided they are within the allowable tolerances. Finished tubes shall be protected both on the outside and the inside diameter to prevent corrosion in transit. Each lot of tubes shall be subjected to the following tests: tension test, flaring test, flattening test, hardness test, and hydrostatic proof test.
