3、1 editorially to show commonly accepted element name Niobium (formerly Columbium) inMarch 2017.1. Scope1.1 This specification covers hot-finished and cold-finishedmartensitic chromium steel bars for high-temperature service.The mechanical properties are developed by suitable heattreatment, as indica

4、ted for each alloy.1.2 Where strength at temperature is a factor, these steelsare generally limited to a maximum service temperature of1200F 650C. For oxidation (scaling) resistance and at lowstresses, these steels are useful to 1450F 790C.1.3 This specification is expressed in both inch-pound units

5、and SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units),the inch-pound units shall apply. The values stated in eitherinch-pound units or SI units are to be regarded separately asstandard. Within the text, the SI units are shown in b

6、rackets.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 noncon-formance with the specification.2.
