1. Scope*

1.1 This specification? covers chromium, chromium-nickel,

and chromium-manganese-nickel stainless steel plate, sheet,
and strip for pressure vessels and for general applications

including architectural, building, construction, and aesthetic
applications.

1.2 The values stated in either SI units or inch-pound units

are to be regarded separately as standard. 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 non-conformance
with the standard.

1.3 This specification is 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 unit:

1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the

responsibility of the user of this standard to establish appro-

priate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in acco
dance 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.

4 Unless otherwise indicated, a grade designation originally assigned by the American Iron and Steel Institute (AISI).
® Yield strength shall be determined by the offset method at 0.2 % in accordance with Test Methods and Definitions A370. Unless otherwise specified (see Specification
A480/A480M, 4.1.11, Ordering Information), an alternative method of determining yield strength may be based on total extension under load of 0.5 %.
“Either Brinell or denoted Rockwell Hardness scale is permissible. For thin materials, see Specification A480/A480M (17.2.1) and Test Methods A370 (18.1.2) on
superficial testing.
© Bend tests are not required for chromium steels (ferritic or martensitic) thicker than 1 in. [25 mm] or for any austenitic or duplex (austenitic-ferritic) stainless steels
regardless of thickness.
© Elongation for thickness, less than 0.015 in. (0.38 mm] shall be 20 % minimum, in 1 in. [25.4 mm]
* Common name, not a trademark, widely used, not associated with any one producer.

&Yield strength requirements shall not apply to material under 0.020 in [0.50 mm] in thickness.

* For $32615, the grain size as determined in accordance with the Test Methods E112, Comparison Method, Plate II, shall be No. 3 or finer.

#840900 (Type 409) has been replaced by $40910, 40920, and S40930. Unless otherwise specified in the ordering information, an order specifying 40900 or Type
409 shall be satisfied by any one of $40910, $40920, or $40930 at the option of the seller. Material meeting the requirements of $40910, $40920, or $40930, may at the
option of the manutacturer be certified as $40900.
‘Material 0.050 in [1.27 mm] and under in thickness shall have a minimum elongation of 20 %.
© Hardness is required to be provided for information only, but is not required to meet a particular requirement.
” The minimum elongation for plates thicker than 0.630 in, [16 mm] shall be 8 %.
© Maximum. Type 420 is usually used in the heat-treated condition (quenched and tempered to a specific range of hardness or tensile strength).
* Hardness conversion tables for superduplex stainless steels do not exist in ASTM E140, The conversion value from HBW to HRC has been added to maintain consistency
with other ASTM standards for these superduplex stainless steels.
