ASTM A358 304/304L pipe EFW is designed for service conditions involving elevated temperatures and pressure. Grade 304 offers balanced mechanical properties along with good weldability and formability, making it suitable for general fabrication and process applications. Grade 304L, with reduced carbon content, is preferred where welding is involved, as it minimizes the need for post-weld heat treatment. Both grades maintain toughness at low temperatures, which supports their use in LNG systems, process plants, refineries, and cryogenic service.

Product range, specification, and certificate
The product range includes EFW pipes in round, square, and rectangular forms, along with other variations such as honed tubes. Manufacturing standards include ASTM A358, A269, and A270 in grades such as TP304, 316L, and 317L. Materials are supplied with inspection documents such as manufacturer test certificates, IBR approval where required, and third-party inspection reports. Testing may include radiographic examination, hardness testing, and other checks based on specification. Pipe sizes typically range from 6NB to 1200NB with multiple schedule options depending on wall thickness requirements.

Packaging
ASTM A358 304/304L Pipe EFW is packed in line with standard export practices to prevent handling damage and exposure during transit. Depending on size and customer requirements, pipes are supplied in bundles, loose (naked), or in wooden crates. Packaging is arranged to maintain surface condition and dimensional integrity during transportation and storage.
