Copper Alloying In ASTM A312 TP904L Stainless Steel Pipes

Copper and nickel protect the pipe where 316L falls short.

Plain 316L Pipe
  • Often insufficient in acid plants
  • Lower alloy content
VS
TP 904L Pipe
  • Copper adds sulphuric acid resistance
  • High nickel resists chloride cracking
  • Molybdenum limits crevice attack
