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

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