Balance

INCOLOY® alloy 27-7MO is an advanced 7 wt% molybdenum content stainless steel offering improved corrosion resistance to the similar alloys with a lower molybdenum content. The combination of a material with good corrosion resistance, high strength and good fabrication characteristics and at a more economical price has established a new candidate for service in many environments where more

expensive alloys have been employed previously. Applications extend to feedwater and process fluid circuits in power plants and in pulp and paper mills, heat exchangers in marine and oil field extraction service and in chemical processing plant.
