What is A312 TP304LN?

304LN pipe to A312/SA312 for general corrosive service. Strength guide: higher strength than 304L at similar corrosion class — confirm SA-312 / PO.

Typical applications

  • Pressure piping needing extra strength vs 304L
  • Process equipment where low carbon weldability and higher allowables matter

Selection guidance

Select 304LN when the datasheet names LN specifically. Closest twins: 304L and 316L for corrosion class.
