Product Description
  • Optimized chemical composition (29Cr-42Ni-Mo-N) for corrosive environment such as black liquor recovery boiler and waste to energy boiler.
  • Excellent general corrosion resistance for both chloride and sulfate alkaline due to high Cr and Ni content.
  • Excellent localized corrosion resistance for such as inter-granular corrosion and stress corrosion cracking due to optimized Ni, Mo, N and extra low C content.
  • Applicable as mono-wall tube and outer component of composite tube.
  • Enough formability, weldability for boiler tube application due to good phase stability.
