2.8 Materials and Mechanical Properties 2.8.1 Steel. Unless otherwise specified, chemical and mechanical properties of steel bolts, except step bolts and elevator bolts, shall conform to all require- ments of ASTM A307, Grade A and shall be stress relieved as required by the standard. Due to peculiarities of the head configurations, steel step bolts and elevator bolts are considered conforming if the ultimate tensile strength in pounds is equal to or greater than 90% of the values indicated in ASTM A307, Grade A. 2.8.2 Other Materials. Additional steel grades are covered in SAE J429. Nonferrous materials are covered in ASTM F468. Corrosion-resistant steels are covered in ASTM F593. Due to peculiarities of the head configura- tions, step bolts and elevator bolts are considered con- forming if the ultimate tensile strength in pounds is equal to or greater than 90% of the full strength material values.
2.9 Identification Symbols 2.9.1 Grade Symbols. Each ofthe products included in this Standard shall be marked in accordance with the requirements of the applicable specification for its chemistry and mechanical properties. 2.9.2 Source Symbols. Each of the products included in this Standard shall be marked to identify the source accepting responsibility for the conformance of the bolt to this and other applicable specifications.
2.10 Finish Unless otherwise specified, round head bolts shall be supplied with natural (as processed) finish, unplated or uncoated.
2.11 Workmanship Bolts shall be free from surface imperfections such as burrs, seams, laps, loose scale, and other surface irregu- larities that could affect serviceability.ASME B18.5 pdf download.
