SAE J524 cold drawn and annealed seamless low-carbon steel pressure tubing intended for use as

hydraulic lines and in other applications requiring tubing a quality suitable for flaring and bending.

SAE J524 Cold Drawn Seamless Pipes,hydraulic fluid lines pipes,hydraulic pressure tubing.

The the cold finished Steel Tubes mainly for hydraulic steel tubing and cold drawn pressure tubing

SCOPE

This specification covers cold drawn and annealed seamless low carbon steel pressure tubing for use as hydraulic lines.

HYDROSTATIC TEST

Tubing supplied under this specification shall have been tested at not less than 1,000 lbs. hydrostatic pressure or higher

in case working conditions require.

CLEANLINESS

It is desired that the inside of tubing shall be bright, clean, and free from grease, drawing compounds, oxide, scale,

carbon deposits, and any contamination that cannot be readily removed by cleaning with alkaline cleaners or benzine.

CORROSION PROTECTION OF INTERIOR OF TUBES

The inside of the tubing having open ends shall be protected by a coating of clean oil to protect the interior of the tubing against

 corrosion during shipment and normal storage periods.The corrosion preventive oil used shall be such that, after extended storage 

periods, it can readily be removed with an alkaline cleaning solution or with benzine (Standard Solvent).

QUALITY

Tubing shall be free from defects and in accordance with the best commercial practice.

CHEMICAL COMPOSITION (percentage by weight)

The tubing shall conform to the following chemical analysis:

Carbon……………0.18 max. Phosphorus……….0.040 max.
Manganese……..0.30 -0.60 Sulphur…………….0.050 max.


 



Seamless low carbon steel tubing annealed for bending — Pressure type.

PHYSICAL PROPERTIES

The tubing shall conform to the following physical requirements

Tensile strength Lb/Sq. inch, minimum………………..45,000

Elongation in 2 inches, minimum………………………..35 percent*

For tubes with an OD of 3/8 inch and less and wall thickness of 0.035 inch and less, a minimum elongation of 30 percent is permitted.

SEAMLESS HYDRAULIC TUBING

A three inch section cut from the tubing shall not crack or show any flaws when flattened between parallel plates to three times the

wall thickness of the tube.

A section of tube approximately four inches in length with the ends burred shall withstand being expanded at one end over a polished

tapered mandrel having an included angle of 60 degrees until the actual average inside diameter is increased 30 percent.

The expansion test shall be made in a die in order to restrict the expansion of 30 percent. The axis of the mandrel should be paralled

to the axis of the tube during the expansion tests.

VARIATIONS

The diameter of the tubing shall not vary from that specified more than the following amounts:

OD Sizes
inches
Outside Diameter, In.
Plus
Minus
Below 3-1/2 to 1-1/2 Incl.
0.010
0.010
Below 1-1/2 to 1/2 ID Incl.
0.005
0.005
Below 1/2 ID
0.003
0.003








When the outside diameter and wall thickness of 1/2 inch to 3-1/2 inch OD tubes are specified, the outside diameter shall conform to

the tolerances given in the above table, and the wall thicknesses shall not vary from that specified more than plus or minus 10 percent.

When less than 1/2 inch ID, the outside diameter shall conform to the tolerances given in the above table. The wall thickness shall not

vary from that specified more than plus or minus 15 percent.

PICKLE BRITTLENESS

Tubing which is pickled to remove scale shall be treated to eliminate pickle brittleness.
