Allegheny Ludlum Stainless Steel Type AL 441HP™ Alloy

 

Subcategory: T 400 Series Stainless Steel; Stainless Steel; Metal

Material Notes:
Iron content above calculated as balance.

Allegheny Ludlum stainless Type AL 441HP™ alloy is a heat resisting ferritic grade providing good oxidation and corrosion resistance for applications like automotive exhaust system components. Dual stabilized with columbium and titanium to provide good weld ductility and resistance to intergranular corrosion in the weld heat affected zone.

AL 441HP™ alloy has been developed for the severe tube bending and forming operations typical in automotive exhaust manifold fabrication. Tight control on carbon and nitrogen levels plus improved mill processing result in enhanced formability is terms of higher tube bending speeds and lower breakage or scrap rate.
