(Specification)Standard Specification for Steel Tie Plates, Low-Carbon and High-Carbon-Hot-Worked
Standard Specification for Steel Tie Plates, Low-Carbon and High-Carbon-Hot-Worked
ABSTRACT
This specification deals with steel tie plates, low-carbon and high-carbon-hot-worked that are used in railroad tracks. The steel shall be manufactured by either basic-oxygen or electric-furnace processes and may be cast by a continuous process or in ingots. Both Grade 1 and Grade 2 tie plates may be sheared, punched, or slotted either hot or cold but only the latter may be placed into an enclosure to assure proper cooling. One bend test shall be made from each identified heat. The specimens for testing shall be taken from finished tie plates, longitudinally with the direction of rolling. They shall be rectangular in section and shall have two faces as rolled. If high carbon tie plates represented by bend tests fail to meet the requirements specified, they may be annealed not more than twice and be resubmitted for testing.
SCOPE
1.1 This specification covers steel tie plates for use in railroad track.
1.2 Two grades of tie plates are described: Grade 1, low-carbon, and Grade 2, high-carbon-hot-worked.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

3.1.5.1 Discussion—
Tie plates of different length can be used with a given rail section with the length chosen based on the traffic density of the track
on which it is to be used.
3.1.6 line holes—located at the edge of the rail seat, these holes allow the spikes to contact the edge of the rail base.
3.1.7 rail seat—the portion of the tie plate that supports the rail.
3.1.8 rail seat cant—tie plates are generally rolled with the rail seat not parallel to the base of the plate so that the rail head is
tilted toward the centerline of track to help offset lateral thrust and provide better wheel bearing on the rail head; the AREA
recommended cant is a ratio of 1:40.

3.1.9 rolled width—the dimension of the finished section as it leaves the rolls and is equal to the length of the tie plate.
3.1.10 sheared length—the dimension to which the finished section is cut and is equal to the width of the tie plate.
3.1.11 shoulder—a ridge parallel to the rail designed to assist in holding the rail in position.
3.1.11.1 Discussion—
The height of the shoulder is about equal to the thickness of the edge of the rail base. If a plate has a single shoulder, the shoulder
is located on the field side of the rail seat to resist the outward thrust of the rail. A double shoulder plate has an additional shoulder
on the gage side of the rail seat. Single shoulder plates may accommodate a desired rail section by adjusting the punching of the
spike holes on the gage side to match the width of the rail base. Double shoulder plates are limited to a single rail base width.
3.1.12 tie plate—a part of the track structure placed under the rail to distribute the wheel load to the tie, cant the rail to the
desired angle, assist in maintaining the track to gage and protect the tie.
3.1.12.1 Discussion—
The tie plate has a rail seat, either flat or canted, either a single or double shoulder parallel to the rail it supports, and is punched
with holes for spikes or other fasteners. The bottom of the tie plate is usually flat, but ribbed or other designs may be used.
3.1.13 width—overall dimension of the plate parallel to the rail it supports.
3.1.13.1 Discussion—
Tie plates are generally from 7 to 8 in. wide.
4. Ordering Information
4.1 Orders for tie plates under this specification shall include the following information:
4.1.1 Quantity: number of pieces.

5. Materials and Manufacture
5.1 Melting Practice—The steel shall be made by any of the following processes: basic-oxygen or electric-furnace.
5.2 The steel may be cast by a continuous process, or in ingots.

specification may be used in the manufacture of either Grade 1 or Grade 2 tie plates.
5.5 Grade 1 tie plates may be sheared, punched, or slotted either hot or cold, at the option of the manufacturer.
5.6 Grade 2 tie plates shall be sheared, punched, or slotted hot, at a temperature best suited to the process, and thereafter placed
into an enclosure to assure proper cooling.
6. Chemical Composition
6.1 The steel shall conform to the requirements for chemical composition specified in Table 1.
6.2 Heat or Cast Analysis:
6.2.1 An analysis of each heat or cast shall be made by the manufacturer to determine the percentages of the elements specified
in Table 1. The analysis shall be made from a test sample taken preferably during the pouring of the heat. The chemical
composition thus determined shall conform to the requirements in Table 1.
