Standard Specification for Chromium, Chromium-Nickel, and Silicon Alloy Steel Bars and Shapes for Corrosion and Heat-Resisting Service
|Publication Date:||10 September 1996|
|ICS Code (Non-ferrous metals in general):||77.120.01|
1.1 This specification covers hot- and cold-finished alloy steel bars, having a chromium content equal to or less than 11.0 % including rounds, squares, hexagons, and hot-rolled or extruded shapes for use in corrosion and heat-resisting service.
1.2 Some steels covered by this specification, especially the high silicon-containing steels, because of their particular alloy content and specialized properties, may require special care in their fabrication and welding. Specific procedures are of fundamental importance, and it is presupposed that all parameters will be in accordance with approved test methods capable of producing the desired properties in the finished fabrication.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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 this specification.
1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished in inch-pound units.
