Grade hub · A312 Seamless · A312 Welded · A213 · A269 · A358 EFW · SS hub · A358 hub
Large-OD fusion-welded 904L pipe. Chemistry: high Ni-Cr-Mo-Cu superaustenitic (≈ 20Cr-25Ni-4.5Mo-Cu).
Use 904L when 316L/317L are inadequate but full nickel alloy is not justified. Compare with 254 SMO / 6Mo and duplex/super duplex on PREN and cost. Always state A358 class with OD × wall.

Standard Specification for Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe for High-Temperature Service and General Applications
ASTM A358 Stainless Steel EFW Pipes specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general Applications.
The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”
This specification covers the grades of alloy and stainless steel listed in Table 1. The selection of the proper grade and requirements for heat treatment shall be at the discretion of the purchaser, dependent on the service conditions to be encountered.
Five classes of pipe are covered as follows:
ASTM A358 Class 1 - Pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
ASTM A358 Class 2 - Pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
ASTM A358 Class 3 - Pipe shall be single welded by processes employing filler metal in all passes and shall be completely radiographed.
ASTM A358 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 6.2.2.1 and 6.2.2.2).
ASTM A358 Class 5 - Pipe shall be double welded by processes employing filler metal in all passes and shall be spot radiographed.
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.
The values stated in either inch-pound units or 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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
904L stainless steel (uns nos894)
Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.
Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the Applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

The A358 EFW Pipes is used in the following Applications:-
Electric-fusion-welded 904L stainless pipe (UNS N08904) to ASTM A358 / ASME SA358 with a specified class.
Large OD / wall combinations are often more practical as EFW from plate when the PO allows A358.
Classes define radiography and heat treatment — quote the class on every enquiry.
See A312 TP904L seamless/welded for smaller OD packages.
