ASTM A 946 : 1995 : R2000

CONTAINED IN VOL. 01.03, 2012 Defines requirements for alloy steels with chromium content equal to or less than 11.0 % in plate, sheet or strip form for corrosion and heat resisting applications.

1.1 This specification covers alloy steels having a chromium content equal to or less than 11.0% in plate, sheet, strip form for corrosion, and heat resisting applications.

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 methods capable of producing the desired properties in the finished fabrication.

1.3 The values stated in 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 the 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.
