ASTM A608/A608M-20

Standard Specification for Centrifugally Cast Iron-Chromium-Nickel High-Alloy Tubing for Pressure Application at High Temperatures

ABSTRACT
This specification covers the standard for iron-chromium-nickel, high-alloy tubes made by the centrifugal casting process intended for use under pressure at high temperatures. The tubing shall be supplied in the as cast condition or as cast with machining on the outside or inside surfaces. The material shall conform to the required chemical composition in carbon, manganese, silicon, chromium, nickel, phosphorus, sulfur, and molybdenum. Tension test shall be performed in the tubing at elevated temperature and shall conform to the required values in tensile strength and elongation. Tubing shall meet several tests such as; pressure test, flattening test, and mechanical test.
SCOPE
1.1 This specification covers iron-chromium-nickel, high-alloy tubes made by the centrifugal casting process intended for use under pressure at high temperatures.  
1.2 The grades of high alloys detailed in Table 1 are intended for applications requiring strength and resistance to corrosion and scaling at high temperatures.    
1.3 Optional Supplementary Requirements S1 to S11 are provided; these call for additional tests to be made if desired.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4.1 Within the text, the SI units are shown in brackets.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
