Grade Overview

SS 441 Sheet / AISI 441 Sheet / EN 1.4509 / 441HT

A titanium and niobium stabilized ferritic stainless steel offering excellent high-temperature strength, oxidation resistance and improved corrosion resistance compared to conventional ferritic grades like SS 409. Titanium and niobium bind carbon and nitrogen, preventing carbide precipitation and enhancing weldability, high-temperature stability and long-term corrosion resistance.

Metallurgical Characteristics & Performance

Each element in SS 441 plays a precise role in delivering exceptional high-temperature performance and corrosion resistance.

Fe
Iron
Base metal forming the primary matrix, providing structural strength and magnetic properties.
Cr
Chromium
Enhances corrosion and oxidation resistance by forming a stable passive oxide layer on the surface.
C
Carbon
Present in low amounts to maintain ductility and weldability while contributing slightly to strength.
Mn
Manganese
Improves hot working properties and contributes to overall toughness.
Si
Silicon
Increases oxidation resistance and enhances strength at elevated temperatures.
Ti
Titanium
Stabilizing element that binds carbon and nitrogen, preventing intergranular corrosion and improving weldability.
Nb
Niobium
Works with titanium to stabilize the structure, enhancing resistance to sensitization and improving high-temperature strength.
S
Sulfur
Improves machinability but is controlled to prevent brittleness.
