ASTM A 358 / ASME SA 358

STANDARD SPECIFICATIOIN FOR ELECTRIC FUSION WELDED AUSTENITIC

CHROMIUM NICKEL ALLOY STEEL PIPE FOR HIGH TEMPERATURE SERVICE1

1. Scope

1.1 this specification2 covers electric-fusion-welded austenitic chromium-nickel alloy steel pipe suitable for corrosive
or high-temperature service, or both. (Although no restrictions are placed on the sizes of pipe which may be furnished
under this specification, commercial practice is commonly limited to sizes not less than NPS 8).

Note 1 - The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional
terms as " nominal diameter,""size,"and "nominal size."

1.2 This specification covers nineteen grades of alloy steel as indicated in Table 1.
The selection of the proper alloy and requirements for heat treatment shall be at the discretion of the purchaser, dependent
on the service conditions to be encountered.

1.3 Five classes of pipe are covered as follows:

1.3.1 Class 1 - Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.

1.3.2 Class 2 - Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.

1.3.3 Class 3 - Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.

1.3.4 Class 4 - Same as Class 3 except that the weld pass exposed to the inside pipe surface may be made without the addition of filler metal(see 5.2.2.1 and 5.2.2.2).

1.3.5 Class 5 - Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.

1.4 Supplementary requirements covering provisions ranging from additional testing to formalized procedures for manufacturing practice are provided. Supplementary Requirements S1 through S6 are included as options to be specified when desired.

1.5 The values stated in either inch-pound units of SI units are to be regarded separately as standard. Within the text,
the SI units are shown in brackets. 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 nonconformace with the specification.

The inch-pound units shall apply unless the "M"designation of this specification is specified in the order.
