1、 Overall Overview
Stainless steel strip is produced using precision cold rolling, continuous rolling, high-precision roller system, and closed-loop thickness control system, combined with annealing leveling and precision slitting processes. The overall thickness tolerance is small, the width is correct, the flatness is high, the edges are regular, and the uniformity of the same roll is stable. It can meet the high-precision processing requirements of precision stamping, electronic accessories, precision hardware, seals, elastic parts, etc.
2、 Thickness accuracy (core indicator)
Cold rolled precision steel strip with strict thickness control
Classification and control of conventional industrial grade, decorative grade, and precision grade:
Ordinary commercial grade: Thickness tolerance ± 0.03 to ± 0.05mm
Precision stamping grade: thickness tolerance ± 0.01 to ± 0.02mm
Ultra precision ultra-thin strip: tolerance can be controlled within ± 0.005mm
Uniformity and stability of the entire roll
Full process online thickness monitoring, with small thickness deviations at the head, tail, middle, and edge to avoid stamping cracking, dimensional deviation, and poor assembly caused by uneven thickness.
3、 Width accuracy
Original factory broadband size standardization, stable tolerance;
In the later stage, high-precision slitting units are used for precision slitting
Conventional slitting: Width tolerance ± 0.1~± 0.2mm
Precision narrow band, electronic specific narrow strip: width tolerance can reach ± 0.05mm
The incision is smooth without burrs, pressure edges, or wavy edges, suitable for automated high-speed stamping.
4、 Flatness and flatness accuracy
By using leveling machines and straightening processes, effectively control edge waves, mid waves, and sickle bends;
Excellent flatness of the plate shape, smooth feeding of the strip, and no deviation or distortion during stamping and feeding;
Suitable for continuous molds, high-speed assembly lines, and automatic cutting and forming.
5、 Edge accuracy
We can provide edge cutting, grinding, and rounded edge processing:
No burrs, cracks, or serrations on the edges;
To avoid bending, cracking, cutting hands, and scratching the mold in the later stage, and to improve the product yield rate.
6、 Length/roll weight accuracy
The cutting error of fixed length and flat cut is small, and the coil diameter and weight are uniform, making it easy for customers to calculate inventory and schedule production.
7、 Accuracy performance of different materials
304/316L austenitic steel strip
Uniform material, strong rolling stability, good overall thickness and dimensional accuracy, suitable for precision parts.
430 ferritic steel strip
Good board shape, high flatness, stable size, and high cost-effectiveness.
201 stainless steel strip
Conventional size stability meets the precision requirements of ordinary stamping and decorative materials.
8、 Summary
Stainless steel strip relies on precision cold rolling equipment and mature rolling processes, with strict control over thickness, width, flatness, and edge quality. It has precise dimensional tolerances, strong consistency throughout the coil, and a flat and stable plate shape.
We can provide various levels of materials including ordinary precision, precision grade, and ultra precision grade according to customer needs, adapting to different precision production requirements such as ordinary hardware, decorative materials, precision stamping, electronic components, sealing accessories, and elastic parts, ensuring stable processing, uniform finished product dimensions, and higher yield rates for customers.
