Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service

قیمت در سایت اصلی:46 دلار

1. Scope*
1.1 This specification2 covers nominal wall and minimum
wall seamless ferritic alloy-steel pipe intended for hightemperature
service. Pipe ordered to this specification shall be
suitable for bending, flanging (vanstoning), and similar forming
operations, and for fusion welding. Selection will depend
upon design, service conditions, mechanical properties, and
high-temperature characteristics.
1.2 Several grades of ferritic steels (see Note 1) are covered.
Their compositions are given in Table 1.
NOTE 1—Ferritic steels in this specification are defined as low- and
intermediate-alloy steels containing up to and including 10 % chromium.
1.3 Supplementary requirements (S1 to S8) of an optional
nature are provided. Supplementary requirements S1 through
S6 call for additional tests to be made, and when desired, shall
be so stated in the order together with the number of such tests
required.
1.4 The values stated in either SI units or inch-pound units
are to be regarded separately as standard. Within the text, the
SI units are shown in brackets. 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. The inch-pound units shall apply unless the “M”
designation of this specification is specified in the order.
