Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications

استاندارد مشخصه صفحات فولادی ضد زنگ کرومیک و یا نیکل- کرومیک مورد استفاده در مخازن تحت فشار و یا کاربردهای عمومی

۱٫ Scope*
۱٫۱ 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.
۱٫۲ 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.
۱٫۳ 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 units.
۱٫۴ 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 appropriate
safety and health practices and determine the applicability
of regulatory limitations prior
