Ordering Information 4.1 Orders for rails under this speciﬁcation shall include the following information: 4.1.1 ASTM designation and year of issue. 4.1.2 Quantity(tons or pieces as appropriate). 4.1.3 Full identiﬁcation of section with dimensional drawing, if required. 4.1.4 Arrangement of drilled bolt holes, if any, with dimensional drawing, if required. 4.1.5 Quantity of right-hand and left-hand (Note 1) drilled rails, drilled both-end rails, and undrilled (blank) rails desired. 4.1.6 Supplementary requirements that shall apply (see S 1 through S 3). 4.1.7Disposition of various classiﬁcations of rails (see 9.4.6 and 9.4.7).
NOTE 1—The right-hand or left-hand end of the rail is determined by facing the side of the rail on which the brand (raised characters) appears.
5. Materials and Manufacture 5.1 Melting Practice—The steel shall be made by any of the following processes: open-hearth, basic-oxygen, or electricfurnace. 5.1.1 The steel shall becast by a continuous process, in hot-topped ingots, or by other methods agreed upon by the purchaser and the manufacturer. 5.2 Discard—Sufficient discard shall be taken from the bloom or ingot to ensure freedom from injurious segregation and pipe. 5.3 Hydrogen Elimination: 5.3.1 Applicability: 22.214.171.124 Rails 60 through 70 lb/yd (29.8 through 34.8 kg/m) are not subject to treatment for hydrogen...
