Processing features<br />
• Isotropic, fine-grained structure without rolling<br />
mill textures<br />
• <strong>High</strong> strength with excellent formability<br />
• Very good blanking and deep-drawing properties<br />
with low earing<br />
• <strong>High</strong> work hardening<br />
• <strong>Strength</strong> is enhanced by ageing briefly<br />
(bake hardening)<br />
• Low carbon content for good welding and<br />
forming behaviour<br />
• Mechanical properties comparable to stainless steel<br />
1.4301 – 1.4310 (ASTM 301 – 305)<br />
Globally unique:<br />
Advantages<br />
• Excellent formability in narrow radii<br />
• Good vibration resistance with high endurance<br />
when subjected to dynamic loads<br />
• <strong>High</strong> elasticity and clamping power<br />
• <strong>High</strong>er electrical conductivity compared<br />
to stainless steel<br />
• Temperature stability up to 300°C<br />
• Light weighting through use of thinner gauge<br />
compared to conventional deep drawing steels<br />
• Process stability and product benefits<br />
through pre-plating<br />
• Suitable in many applications as an alternative to<br />
stainless steels, non-ferrous metals and carbon steels<br />
• Elimination of process steps such as downstream<br />
plating or annealing<br />
• Improvement of output<br />

<strong>High</strong> <strong>Strength</strong> <strong>Strip</strong> combines<br />
the familiar Corus Special <strong>Strip</strong><br />
high-grade surfaces and surface<br />
coatings with the properties of<br />
cold rolled strip. <strong>High</strong> <strong>Strength</strong><br />
<strong>Strip</strong> is perfect for a vast range<br />
of applications and in many<br />
cases it delivers more value for<br />
money than stainless steels,<br />
non-ferrous metals and carbon<br />
steels.<br />
