Frequently Asked Questions
The following questions reflect the most common technical concerns raised by appliance, furniture, and automotive part manufacturers. These buyers focus on thickness tolerance, surface finish quality, and forming performance, as CRC is often used for visible or precision-fitted components.
What is the main advantage of CRC compared to HRC?
CRC offers tighter thickness tolerance, smoother surface finish, and improved flatness, making it suitable for precision forming and painted applications.
Is CRC suitable for deep drawing?
Yes, specific grades with appropriate elongation are designed for deep drawing. Grade selection should match forming depth and tooling design.
Does cold rolling increase strength?
Cold reduction increases strength and hardness compared to hot rolled steel, but may reduce ductility slightly depending on reduction level.
What surface finishes are available?
CRC is commonly supplied with standard smooth finish suitable for painting or further coating. Surface roughness can be adjusted based on application requirements.
How is dimensional accuracy controlled?
Thickness and flatness are monitored during rolling and leveling processes. Mill test certificates provide confirmation of mechanical properties and chemical composition.
