Anotace textu normy ASTM A67-00(2021) :
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.
