Prismatic Battery Module SUS301 Stainless Steel Strap 22mm Width 1.0mm Thickness Custom Configuration Welding Compatible

Product Overview

The SUS301 Stainless Steel Strap is a custom-configured 22mm width × 1.0mm thickness solution engineered specifically for prismatic battery module assembly. Manufactured from SUS301 austenitic stainless steel, this strap delivers 16% wider clamping contact area than standard 19mm configurations for enhanced cell stack stability. The metastable austenitic structure enables work hardening for increased post-forming strength, while maintaining excellent weld compatibility with both resistance spot and laser welding processes. Available in 19mm, 22mm, and 30mm custom width options to match specific prismatic cell format and module design requirements.

Product Features

• Wider Clamping for Prismatic Cells: 22mm width provides 16% more contact area than standard 19mm, delivering enhanced cell stack stability for prismatic lithium battery modules without adding strap quantity.
• SUS301 Work Hardening Capability: Metastable austenitic structure enables controlled cold working to increase strength post-forming, achieving higher clamping forces without increasing material thickness or weight.
• Custom Specification Flexibility: Available in 19mm, 22mm, and 30mm widths — select the optimal dimension for your specific prismatic cell format with tailored lead time.
• Weld-Verified Performance: Independently tested welded joint strength with approximately 78-80% joint efficiency for reliable automated production integration.
• Insulation Film Compatible: Surface insulation resistance ≥1000MΩ at 1000V DC with PET insulation film lamination — ready for insulated strap applications.
• Dual Surface Finish Options: 2B cold rolled matte (standard) or bright polished (optional) to match module aesthetic and functional requirements.
