Steel Grade

The steel grades covered under ASTM A376 include:

  • TP304: Standard grade with balanced carbon and chromium content.
  • TP304H: Higher carbon content for enhanced strength.
  • TP304N: Nitrogen-alloyed grade for improved creep resistance.
  • TP304LN: Low-carbon, nitrogen-alloyed grade for superior corrosion resistance.
  • TP316: Molybdenum-alloyed grade for enhanced pitting corrosion resistance.

Application

These materials are widely used in:

  • Heat exchangers
  • Boilers
  • Steam lines
  • Petrochemical piping systems
  • Power plants
  • Oil refineries

Possible Alternate Grades

  • TP309S: High-temperature resistant grade with higher chromium and nickel content.
  • TP310S: Superior oxidation resistance compared to TP304.
  • TP321: Titanium-stabilized grade for improved intergranular corrosion resistance.
  • TP347: Stabilized grade for high-temperature applications.
