Post-rolling tension leveling eliminates coil set (<0.5 mm/m camber).
Custom Chemistry
Low-carbon grades (C ≤0.15%) with Nb/V microalloying for enhanced formability.
Frequently Asked Questions
What are the primary applications of these cold-hardened steel coils?
These coils are highly optimized for manufacturing high-wear components such as industrial cutting blades, lock components, and high-cycle fatigue springs.
How does the wear resistance compare to annealed steels?
With a carbide volume fraction of ≥8%, these cold-hardened steel coils extend tool and component service life by up to 4 times compared to standard annealed options.
What dimensional precision can be expected from this steel?
Thanks to advanced post-rolling tension leveling, coil set is effectively eliminated, maintaining an exceptionally straight camber of less than 0.5 mm/m.
Is the chemical composition of the steel customizable?
Yes. We offer custom chemistry options including low-carbon grades (C ≤0.15%) integrated with Nb/V microalloying to achieve superior formability properties.
Does the zinc-iron alloy coating affect weldability?
No, the specialized zinc-iron alloy coating is designed to maintain high weldability while providing robust corrosion resistance for demanding environments.
