1. Scope
1.1 This specification covers iron-chroium-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 additionaltests to be made if desired.
1.4 The values stated in inch-pound units are to be regarded as the standard.
