Import 420j1 420j2 Stainless Steel Coil Strip — Buy in Bulk from Supplier in China

The 420J1 and 420J2 stainless steel coil strips from Taian Henson Metal Co., Ltd. are martensitic grades designed for applications requiring hardness and wear resistance. These strips are produced in coil form with custom lengths and feature a smooth surface finish to minimise friction in industrial environments. The material is supplied in both annealed and hardened states, allowing buyers to select the condition best suited to their processing needs, such as machining or forming before final heat treatment.

Compositionally, 420J1 and 420J2 are chromium-based stainless steels with carbon content optimised for hardness, typically around 0.15-0.40%. The strips exhibit good corrosion resistance in mild environments, though they are less resistant than austenitic grades like 304. Standard industry tolerances for thickness on coil strips of this type are ±0.05 mm for precision applications, though exact tolerances should be confirmed with the supplier. These grades are also known for their polishability, making them suitable for decorative as well as functional components.

These coil strips are specified by buyers in the automotive sector for trim and structural components, in aerospace for non-critical brackets, and in manufacturing for blades, springs, and wear-resistant parts. Taian Henson Metal Co., Ltd. offers the material in varying thicknesses, with the coils packaged for export from China. Buyers should verify whether the strips are supplied in annealed or pre-hardened condition, as this affects machinability and the need for post-processing heat treatment. Incoterms and packaging details are provided on request.

Taian Henson Metal Co., Ltd. is based in China and operates as an imported-tier supplier with a harbor trust classification. The company specialises in stainless steel products, including coil strips in martensitic and other grades, catering to industrial buyers who require precision and specific material properties. The supplier profile does not state a response rate or average response time, indicating that direct contact may require follow-up for timely communication.

The listing confirms the supplier’s focus on stainless steel coil strips, with no additional details provided on company size, client base, or operational history. Buyers are advised to request verification of production capabilities, quality control processes, and any applicable certifications directly from Taian Henson Metal Co., Ltd. The absence of stated certifications in the profile means these must be confirmed separately, as they are not guaranteed by default.
