What specific (e.g., carbon steel, 316 stainless steel) are you considering?

Embrittlement causes ductile metals to become brittle, leading to sudden, catastrophic cracks under stress. Standard piping codes, like ASME B31.3 (Process Piping), do not fully account for the aggressive nature of high-pressure hydrogen. ASME B31.12 bridges this gap by enforcing: Lower allowable stress limits for metals.

Send a copy of the standard (or relevant excerpts) to your powder suppliers. Require that their Certificate of Analysis (CoA) map to ASME B3112 clauses. If they refuse, find a new supplier—non-compliance will invalidate downstream part certifications.

ASME B31.12 is a code published by the American Society of Mechanical Engineers (ASME) that specifically governs . It provides stringent requirements for the design, construction, operation, and maintenance of infrastructure used to transport gaseous and liquid hydrogen. The code is divided into three primary parts:

Part PL governs transport pipelines that transfer hydrogen over long distances outside plant boundaries.

Part IP focuses on hydrogen piping systems typically found within industrial plant boundaries. This includes: Refineries and chemical plants.
