Corrosion Resistance
Refer to NACE (National Association of Corrosion Engineers) for specific recommendations.
Available Finishes
- #1 - Hot rolled annealed and descaled for applications where smooth decorative finish is not required
- #2D - Dull finish for deep drawn parts and applications requiring lubricant retention
- #2B - Smooth finish with brighter appearance than 2D
- #BA - Bright annealed cold rolled
- #CBA - Course bright annealed cold rolled matte finish
- #2 - Cold Rolled
- #2BA - Smooth glossy finish for lightly formed applications
- Polished - Various grit finishes for specific requirements
Not all finishes are available for all alloys - Contact sales for availability.
Wire Finishes
- Clean bright annealed or bright annealed and cold rolled
- Grease - Ultra-bright finish for decorative applications
- Soap - Soap acts as lubricant, not removed from tempered wire
Contact for custom wire finishes.
Forming & Heat Treatment
Cold Forming: Type 444 provides excellent formability and can be readily deep drawn and spin formed. Stretch forming is limited.
Heat Treatment: Type 444 is non-heat treatable.
