Standard Specification for High-Temperature Bolting Materials, with Expansion Coefficients Comparable to Austenitic Stainless Steels
|Publication Date:||1 October 2004|
|ICS Code (Fasteners in general):||21.060.01|
NOTE 1 - Other bolting materials are covered by Specification A 193/A 193M and Specification A 437/A 437M.
Supplementary Requirement S 1 of an optional nature is provided. This shall apply only when specified by the purchaser in the order.
This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.
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 must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
