Product Overview

Stainless Steel Precision Strip is an ultra-thin, narrow stainless steel material manufactured through cold rolling finishing, stress leveling and high-precision longitudinal slitting of stainless steel mother coils. Produced according to ASTM A666, GB/T 4239 and EN 10088 standards, it is designed for precision applications requiring tight dimensional control, stable flatness and consistent material performance.

The available thickness range is 0.03–2.0mm, with customized ultra-thin specifications down to 0.01mm. Slitting widths can be customized from 3–1200mm, while thickness tolerance can be controlled within ±0.01mm according to the product requirements.

A wide range of stainless steel grades is available, including AISI 301, 304, 316L, 321, 430 and 201 series, together with corresponding SUS, EN and GB grades. This allows buyers to select materials according to elasticity, corrosion resistance, temperature resistance and precision forming requirements.

Surface options include 2B, BA mirror, HL hairline and etched base material, with deburring and edge rounding available for precision processing. The strip is used for electronic spring contacts, lithium battery steel strips, precision instrument gaskets and shims, corrugated pipe materials, miniature hardware and automotive precision fittings.
