What Is SUH409L?
SUH409L is a low-carbon, titanium-stabilized ferritic stainless steel widely used in automotive exhaust systems and heat-resistant structural parts. Compared with general carbon steel, SUH409L offers better corrosion resistance, oxidation resistance, and forming performance.
As a precision processing cold rolled steel coil manufacturer, we supply SUH409L cold rolled stainless steel coils in customized thickness, width, hardness, edge condition, and coil weight according to buyers' production requirements.
Oxidation Resistance
Maintains structural integrity and surface quality in temperatures up to 850 ?C, ideal for exhaust manifolds.
Superior Weldability
Titanium stabilization prevents hardening and sensitization in the heat-affected zone.
Thermal Fatigue
Resistant to the stresses of frequent heating and cooling cycles inherent in automotive operations.
費用対効果
A stable, low-nickel solution providing a price advantage over austenitic grades like 304.
