Metallurgical Characteristics & Performance

Each element in SS 439 plays a precise role in delivering exceptional durability and thermal performance.

Fe
Iron
Base metal providing structural strength to the alloy.
Cr
Chromium
Improves corrosion and oxidation resistance by forming a protective oxide layer.
Ti
Titanium
Stabilizes the steel by binding carbon and nitrogen, preventing carbide formation.
C
Carbon
Enhances strength but is kept low to maintain corrosion resistance.
Mn
Manganese
Improves toughness and hot working properties of the alloy.
Si
Silicon
Enhances oxidation resistance and strength of the steel.
N
Nitrogen
Improves strength; controlled by titanium stabilization in this grade.
P / S
Phosphorus / Sulfur
Controlled at low levels to maintain ductility, weldability and toughness.
