Stainless steel catalytic converter flange vs. carbon steel plate flange
1️⃣Material and corrosion resistance
Stainless steel catalytic converter flange: mostly made of stainless steel (such as 304/316), resistant to high temperature (800°C+) and exhaust gas corrosion, ensuring sealing.
Carbon steel plate flange: carbon steel material, low cost but easy to oxidize, requires coating for corrosion protection, suitable for normal temperature/medium temperature environment.
2️⃣Application scenario
Stainless steel catalytic converter: dedicated to automobile exhaust system, harsh environment (high temperature, chemical corrosion).
Carbon steel plate flange: general industrial pipeline (water, oil, gas), petrochemical, construction and other ordinary working conditions.
3️⃣Performance focus
Stainless steel catalytic converter flange: emphasizes sealing (leakage prevention, meeting emission standards).
Carbon steel plate flange: focuses on pressure strength and economy.
4️⃣Cost
Stainless steel flanges are expensive, carbon steel is more economical.
According to the working conditions-choose stainless steel catalytic converter flanges for high temperature corrosion, and carbon steel plate flanges for conventional needs.
