Composition Analysis
Metallurgical Characteristics & Performance
Each element in SS 409M plays a precise role in delivering exceptional durability and thermal performance.
Cr
Chromium
Provides corrosion and oxidation resistance; forms a protective passive layer in atmospheric and high-temperature environments.
Ti
Titanium
Stabilizes carbon to prevent intergranular corrosion; improves weldability and high-temperature durability.
C
Carbon
Increases strength and hardness; low levels ensure good weldability and minimize carbide precipitation.
Mn
Manganese
Enhances tensile strength, toughness, and hot-working properties; helps in deoxidation during steelmaking.
Si
Silicon
Improves oxidation resistance and high-temperature performance; also acts as a deoxidizer.
P
Phosphorus
Slightly improves strength and atmospheric corrosion resistance; excess can reduce ductility.
S
Sulfur
Improves machinability but is kept low to maintain ductility and toughness.
Fe
Iron
Base metal providing structural strength, magnetic properties, and support for the ferritic microstructure.
