420 Stainless Steel Strip & Slit Coil

If you are looking for high-hardness, wear-resistant stainless steel strip and slit coil for precision components, blades, and industrial tooling, GNEE supplies 420 Stainless Steel Strip & Slit Coil in compliance with ASTM A240/A480, ASTM A666, EN 10088-2, JIS G4305, and GB/T 4237 standards.

Our 420 stainless steel strip and slit coil (UNS S42000) is manufactured through electric furnace melting, AOD refining, hot rolling, precision cold rolling, annealing or quenching and tempering, followed by pickling or polishing, ensuring uniform microstructure and stable mechanical performance. These products are widely used in cutting tools, surgical instruments, industrial springs, valve components, and precision mechanical parts.

After heat treatment, 420 cold rolled coil can achieve a tensile strength of 700–900 MPa, with hardness ranging from 200–500 HB, depending on the treatment condition. Thickness typically ranges from 0.2–3.0 mm, with customizable widths according to customer requirements, supplied in coil, slit strip, or cut-to-length formats. Surface finishes include 2B, BA, No.4, and polished, meeting both functional and decorative needs.

420 Stainless Steel vs. 304 and 316

Compared with austenitic stainless steels such as 304 and 316, 420 stainless steel strip offers higher hardness and superior wear resistance at a lower material cost, while maintaining adequate corrosion resistance in dry or mildly corrosive environments. The recommended continuous service temperature is generally up to 600°C, making it suitable for applications requiring strength, durability, and cost efficiency.
