InCroX® high-chromium alloy - new burner's generation material
InCroX® material of the future for PellasX burners is based on a group of high-chromium alloys with heat-resistant and incandescent resistant properties.
InCroX® is a high-chromium alloy with a chromium content from 24% to 32%, which in the form of a compound with carbon and silicon has excellent corrosion resistance, including high temperature corrosion.
The burner combustion chamber made of InCroX® withstands high temperature loads much longer than heat-resistant steel, mainly due to its casting in the mold.
1.4841 heat-resistant steel has an average chromium content of 25% and nickel 20%. It is mainly corrosion resistant due to chrome.
InCroX® high-chromium alloy is characterized by a chromium content of 25%, while nickel is only 4-5%, silicon 1.5%, and manganese and moblibdenum 1% (molybdenum increases resistance to pitting corrosion, nickel improves its plasticity).
The processing of heat-resistant steel, i.e. welding and bending, changes its structure and creates corrosion centers. The casting of the body made of InCroX® high-chromium heat-resistant and incandescent-resistant alloy is not subjected to any additional plastic works or welding, which affects its resistance to thermal overloads and to its lifespan.
