Basic Properties for Meeting Diversified Needs

The basic properties of product are under involvement of Nippon Steel Corporation advice and supervision from time to time.

Corrosion Resistance

Each surface treatment enhances the corrosion resistance of all rust

Fingerprint Resistance

EQS1 and EQF1 have excellent fingerprint resistance

Lubricity

EQS1 and EQF1 show only a small dynamic friction coefficient and offer favorable press formability

Paint Adhesiveness

EP is particulary excellent in paint adhesiveness

Conductivity (Grounding Property)

EQS1 has excellent grounding properties

Alkaline Resistance

Each surface treatment shows no change in the range of pH10

Solvent Resistance

EQS1 & EQF1 treatment exhibits excellent solvent resistance

Heat Resistance (Resistance to Heat-induced Color Fading)

EQS1 has less color fading caused by high temperature

Spot Weldability

Each surface treatment is free of welding problems
