Product introduction
The metal honeycomb substrate made by metal steel coil, the metal steel grade is usually EURO grade 1.4725, China grade 0Cr25Al5/0Cr21Al6 for Core, EURO grade 1.4521/1.4016/1.4301 and USA/Japana grade SUS444/SUS441/SUS430/SUS304 for Shell.
The Cell density usually from 25CPSI to 1000CPSI, the minimum thickness of the wall is 0.04mm. The open spaces in the cross-sectional area are larger than 90% of the frontal area, so resistance to the flow of gases through the holes is low, which minimizes energy consumed forcing gases through the structure.
The metal honeycomb substate has excellent thermal conductivity and low heat capacity, The catalyst light-off time short.
The metal honeycomb substate match with all kinds of catalyst raw material, such as Rare Earth, Alumina, Platinum Group Metal (PGM, most commonly platinum, palladium, and/or rhodium) coated on the wall surface of the holes.
Product feature
