Corrosion-focused tooling
Patt Corrosion steel for extrusion tooling
Patt Corrosion prioritizes corrosion resistance for melt passages, dies and precision tooling exposed to aggressive processing residues and cleaning environments. Its lower working-hardness range supports a toughness-focused balance for components where corrosion is the principal material-selection driver.
Where this grade fits
Melt passages, dies and precision tooling exposed to aggressive residues or cleaning environments, where corrosion is the main material-selection driver.

Specify the component and its working conditions
Send the drawing, polymer or contact medium, working temperature, loading, wear or corrosion issue, finish and cleaning method. Patt can review the steel, machining and surface-treatment route together.
