ASTM A759-10

Standard Specification for Carbon Steel Crane Rails

ABSTRACT
This specification covers for carbon steel crane rails of special designs only, and nominal weights for crane runway use. Manufacturing practice shall follow strict procedures for melting, discard, control cooling, end hardening, high strength rails, chamfering, and ends prepared for electric arc welding. The material shall undergo heat or cast analysis and product analysis shall be within the specified limits on chemical composition of carbon, manganese, phosphorus, sulfur, and silicon. Materials that fail to conform to the requirements of this specification shall be rejected and be reported to the manufacturer or supplier promptly in writing.
SCOPE
1.1 This specification covers carbon steel crane rails of special designs only, and nominal weights of 104 lb/yd (51.6 kg/m) through 175 lb/yd (86.8 kg/m) for crane runway use.  
1.2 When standard tee rail sections are desired, they shall be ordered in accordance with Specification A1.  
1.3 Supplementary Requirements S1 through S3 of an optional nature are provided. They shall apply only when specified by the purchaser in the order.  
1.4 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.
