ASTM A476/A476M-00

Standard Specification for Ductile Iron Castings for Paper Mill Dryer Rolls

SCOPE
1.1 This specification covers ductile iron castings for use in pressure containing paper mill dryer rolls at temperatures up to 450oF [230oC].
1.2 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of a casting and those of a test specimen cast from the same iron (see Appendix S1).
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
