Read MoreQuick ViewA519 Seamless Mechanical Tube
ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified

Read MoreQuick ViewSAE J525 Welded & Redrawn Steel Tubes
J525 Hydraulic Tube is welded low-carbon steel tubing annealed for bending and flaring with many uses. Used for pressure lines in applications requiring high-quality tubing for bending, flaring, forming, and brazing. Typical uses include Heavy Equipment, Agriculture, Off-Road Vehicles, Automotive, Steering and Transmission components, Process and Utility, and other Hydraulic applications.
In addition, the manufacturing process of our J525 high-pressure tubing includes several cold-drawn reductions, intermediate anneals, and then a dead-soft anneal after final sizing. The resulting tubing is consistent of high quality that is easy to bend and flare.
Much like J524, J525 is used in hydraulic applications, both with the same chemical and mechanical properties. The difference is that J525 is welded starting as flat stock. Where flaring is a requirement, J524 Seamless is typically the preferred product. However, both are of high quality and have comparable specifications.

Welded Low-Carbon Steel Tubing Suitable for Bending,Flaring,Beading,Forming and Brazing
The SAE J526 Standard covers electric-resistance welded single-wall low-carbon steel pressure tubing intended for general automotive, refrigeration, hydraulic, and other similar applications requiring tubing of a quality suitable for bending, 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 that would be caused by the ID weld bead. The material produced to this specification is intended to service pressure applications where severe forming and bending is not required. As this material may exhibit mechanical properties that reduce some desired forming characteristics versus SAE J356, the severity of the forming requirements of the finished assembly should be considered when utilizing material produced to this specification.If you need more information,please contact sales@grandsteeltube.com -
Read MoreQuick ViewSAE J527 Copper Brazed Bundy Steel Tube
1.A copper plated steel strip is pulled into the primary tube rollers, and become 720 degrees wrapped after going through a set of the rollers.
2.Then the wrapped tube goes into the welding chamber where the tubes are brazed. The temperature within the chamber is controlled above the copper melting temperature, so the copper layers are melted and spread into the steel surfaces. The tube is heated here in the chamber with protection gas filled so there is no oxidizing of the copper or steel, and also no water will be left to avoid any rust.
3.After the welding stage, the tube goes into the cooling section where it gets cooler, and also it is monitored online simultaneously by the Eddy current scanning device. Any abnormal section shape or un-seamed welding would be observed from the monitor screen.
4.The tubes are finally wound to be easily packed and stocked.
This process of Bundy tube production, compared with other methods, are widely accepted for its high production rate yet instant monitoring of the welding quality.

Read MoreQuick ViewSAE J524 Seamless Steel Tube
SAE J524 covers cold drawn and annealed seamless low-carbon steel pressure tubing intended used for hydraulic lines and other applications. The J524 Seamless Hydraulic Tubing is especially favorable for flaring and bending, some industrial uses include aircraft, automotive, locomotive, vehicle, heavy equipment, and agricultural applications. Wiho metals supply and stock a large inventory of SAE J524 seamless tubing for the hydraulic applications and where fittings, couplings, and fluid lines are used. In addition, all of the tubes have an exceptionally bright and clean OD and ID.
