This specification covers centrifugally cast ferritic/austenitic steel pipe intended for general corrosive service. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. The pipe shall be made by centrifugal casting process and furnished in the specified heat-treatment condition. The pipe shall also be machined. The grades shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, nitrogen, copper, and cobalt. Heat analysis and product analysis shall be done. Tensile requirements shall conform to the specified tensile strength, yield strength, and elongation; and hardness requirements shall conform to the specified Brinell and Rockwell C values. Tension test shall also be made.
1.1 This specification covers centrifugally cast ferritic/austenitic steel pipe intended for general corrosive service. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.
1.2 Optional supplementary requirements are provided when additional testing may be required.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of each other. Combining values from the two systems may result in nonconformance with the specification.
1.4 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.
