Super corrosion resistance EGNIS

Combustion chamber incinerator and biomass boiler is filled by chlorine gas occurred in harsh environment at high temperature of 500 to 1,000 ℃. So, the grate and air nozzle installed at the furnace bottom is deteriorated significantly due to corrosion caused by oxygen and chlorine. Our developed 「EGNIS」 material shows excellent corrosion resistance in the incinerator environment and drastically improves grate and nozzle life.

Super wear resistance G

The air nozzle installed at the furnace bottom of biomass boiler wear hard by stirring silica sand collision during nozzle hardness decrease at high temperature.
We developed 「G」 material which has high hardness at high temperature range and improves nozzle life drastically by excellent wear resistance.

Characteristic.

• Wear resistance at high temperature.
• Weldable and high toughness.
