Enhancing work-hardened steel strip performance with four-high rolling mill technology

PPinox uses a reversible four-high rolling mill for the production of work-hardened stainless steel strips. Equipped with 4 rolls, this mill delivers high rolling pressures and enables a total thickness reduction of up to 60%, ensuring excellent dimensional accuracy.

This technology has allowed PPinox to expand its product range and improve its ability to meet the demands of industries such as precision mechanics, spring manufacturing, and chain production, where tight dimensional tolerances and mechanical properties are critical.

Continuous control throughout the rolling process

The rolling process ensures uniform thickness and homogeneity along the length of the strip. This is essential to maintain consistent mechanical characteristics, particularly hardness and strength, which are critical for applications such as springs and mechanical components subject to high stress. Thanks to in-line electronic control, every meter of strip is continuously monitored to detect dimensional or surface defects, ensuring a final product that meets the specified requirements.

PPinox’s approach to work-hardened steel strips

PPinox manufactures work-hardened strips in thicknesses ranging from 0.20 mm to 3 mm, and widths up to approximately 300 mm. This dimensional flexibility supports a wide range of applications, from small precision parts to heavy-duty strips for chain and spring production. The work-hardening achieved through the four-high rolling mill enhances the material’s mechanical properties, delivering strips with high hardness and strength while maintaining good workability.

The four-high rolling mill is integrated into a production line featuring advanced surface cleaning equipment to remove contaminants and prepare the strips for any downstream treatments. This ensures the highest aesthetic and functional quality, a key requirement in high-precision applications.

PPinox specializes in processing and distribution of stainless steel semi-finished products for various industrial sectors. Its product range includes strips, flat bars, special profiles, and other semi-finished products, ensuring mechanical property compliance and dimensional precision.
