Project Description

Product Description:

Super Austenitic Stainless Steel Seamless Pipes are advanced corrosion-resistant tubular products designed for demanding industrial applications. These pipes are characterized by their high Pitting Resistance Equivalent Number (PREN) of ≥40%, calculated as [Cr] + 3.3[Mo] + 16[N].

Key Features:

  1. Superior Corrosion Resistance: Excellent resistance to pitting and crevice corrosion in harsh chloride-containing environments.
  2. Enhanced Mechanical Properties: High yield strength and excellent overall mechanical performance.
  3. Improved Workability: Good machinability and fabrication characteristics.

Grades:

  • N08904 (904L)
  • N08367 (6Mo)
  • S31254 (6Mo)
  • S30432
  • S31042

Key Standards:

  • ASTM A312: Seamless and welded austenitic stainless steel pipes
  • ASTM A269: Seamless and welded austenitic stainless steel tubing for general service
  • ASTM B673, B674, B675, B676, B677, B690: Various specifications for super austenitic alloys

Applications:

Ideal for use in severe corrosive conditions where traditional high-molybdenum (>4%) austenitic stainless steels may be inadequate. These pipes offer improved resistance to localized corrosion and enhanced thermal stability of the microstructure.

Super Austenitic Stainless Steel Seamless Pipes represent a significant advancement in material technology, offering superior performance in challenging environments across various industries.
