Composition Analysis

Metallurgical Characteristics & Performance

Each element in SS 409 plays a precise role in delivering exceptional durability and thermal performance.

Cr
Chromium
Provides corrosion and oxidation resistance by forming a protective passive oxide layer.
Ti
Titanium
Stabilizes carbon to prevent intergranular corrosion and improves weldability and high-temperature performance.
C
Carbon
Increases strength and hardness but must be controlled to maintain weldability and corrosion resistance.
Mn
Manganese
Enhances strength, toughness, and hot working properties while acting as a deoxidizer.
Si
Silicon
Improves oxidation resistance and high-temperature performance and aids in deoxidation during steelmaking.
P
Phosphorus
Slightly increases strength but can reduce ductility and toughness if present in excess.
S
Sulfur
Improves machinability but may reduce ductility and weldability when excessive.
Fe
Iron
Forms the base structure of the alloy, providing overall strength and magnetic properties.
