Alloy 347/347H


Introduction :

Fortune Ferroment Inc makes alloy 347/347H stainless steel of austenitic chromium and columbium. Organized, these metals deflect leftover substances instead of fascinating them. This prevents erosion and makes your bars, pipes, and pipe fittings last extensive. If your business needs stainless steel pipes to handle chemicals, alloy 347H may be the perfect material.

Other benefits of the Alloy 347/347H physical include that it can withstand temperature differences of 800 ̊ to 1600 ̊ ̊ F. So if you plan on heating and cooling metal to redesign it, choose alloy 347H.

Uses of the Alloy 347H Pipe

The ability to withstand high temperatures and corrosion makes this one of our best-selling pipes. These special properties make it ideal for many industries, including the following:

  • Petroleum refining
  • Chemical processing
  • Steam service
  • Food processing
  • Pharmaceutical production
  • Waste heat recovery
  • Exhaust Systems
