Cold Rolled Precision Stainless Steel Strips
Manufacturing Process
Cold Rolled Precision Stainless Steel Strips
Our manufacturing process integrates advanced cold rolling technology, precision annealing systems, and high-end finishing lines to ensure superior quality, consistency, and performance of stainless steel strips.
20 HI Cold Rolling Mills
Thickness close to nominal is achieved through Aalto Gauge Control (AGC). Flat shape of CRCA Sheets is ensured through shiftable Intermediate Rolls (IMR). Reduced edge drop and improved grain structure are achieved due to higher reduction and optimized bite angle during rolling.
Degreasing Lines
Removes oils, dust, and contaminants from strip surfaces ensuring cleanliness for downstream processing.
Bright Annealing Lines
Bright annealing is a process of heating, soaking and controlled cooling of coils in a non-oxidizing atmosphere. It relieves internal stresses developed during cold rolling, restores ductility, and improves formability. Solution annealing dissolves chromium-rich carbides formed during thermo-mechanical processing. The use of 100% inert atmosphere ensures a clean, bright, and defect-free surface finish.
Continuous Annealing & Pickling Lines
Annealing relieves stresses from cold rolling and restores ductility. Pickling removes annealing oxides, oils, and surface contaminants. It eliminates the chromium-depleted layer and ensures superior corrosion resistance, stainless steel suitable for high-performance applications.
Skin Pass Mill
Eliminates stretcher strain improves surface finish (2B), and enhances strip flatness.
Tension Leveler Machine
Applies controlled tension beyond yield strength to improve flatness and remove internal stresses, ensuring dimensional stability of strips.
Precision Slitting Lines
Slitting converts master coils into narrow strips as fine as 3.5 mm, enabling customized widths for diverse applications.
Deburring Lines
Removes sharp burrs formed during cutting operations, improving safety, reducing stress concentration, and enhancing fatigue life of components.
Round Edge Line
Produces smooth, rounded edges for improved handling, reduced chatter, and enhanced product life cycle.
Oscillating Winding
Produces large, tightly wound coils with improved packaging efficiency, reduced handling time, and enhanced transport stability.
