Precision-Slit Stainless Steel Stripping | 201, 301 & 309S Grades
Product Overview
Our stainless steel stripping solutions are engineered for industries demanding precision, durability, and adaptability. Designed with grades 201, 301, and 309S, these strips undergo advanced cold-rolling and precision-slitting processes to meet exacting tolerances (±0.01mm) for aerospace, automotive, and construction applications. Whether used as stainless steel strip roll material for industrial machinery or stainless steel seam strips for structural assemblies, our products deliver unmatched performance in corrosive and high-stress environments.

Performance Characteristics
1. Tensile & Bend Strength
- Tensile Strength:
- Grade 201: 450–600 MPa | Ideal for cost-effective applications like architectural trims and kitchenware.
- Grade 301: 690–860 MPa | Enhanced strength post-cold working, perfect for automotive springs and aerospace fasteners.
- Grade 309S: 620–800 MPa | Exceptional heat resistance (up to 980°C) for furnace components and exhaust systems.
- Bend Strength:
- Stainless steel stripping retains ductility even at subzero temperatures (-50°C), critical for Arctic pipeline clamps and cryogenic equipment.
2. Weight Calculation
Use the formula:
Weight (kg) = Width (mm) × Thickness (mm) × Length (m) × Density (7.93 g/cm³)
Example: For a 300mm-wide, 2.0mm-thick, 50m-long strip:
300 × 2.0 × 50 × 7.93 = 237.9 kg
3. Rust Prevention
While stainless steel stripping inherently resists oxidation due to chromium content (10.5–20%), prolonged exposure to chlorides (e.g., coastal environments) or acidic substances can trigger pitting. Our strips undergo passivation treatments to thicken the chromium oxide layer, reducing corrosion risks by 50%.
4. Identification & Marking
- Laser-etched labels include: Grade (e.g., 309S), Batch Code, Thickness/Width, and Compliance Standard (ASTM/EN).
- Color-coded edges: Green for 201, Silver for 301, Gold for 309S.
Manufacturing Process
| Stage | Description |
|---|---|
| Cold Rolling | Precision thickness reduction (tolerance ±0.01mm) for uniform grain structure. |
| Annealing | Heat treatment at 1010–1150°C to restore ductility and corrosion resistance. |
| Pickling | Hydrochloric acid bath to remove impurities and oxide layers. |
| Precision Slitting | High-speed cutting to produce narrow stainless steel strip roll material for electronics and HVAC systems. |
| Surface Finishing | Custom textures (e.g., brushed for stainless steel seam strips) via grinding or polishing. |
Applications
- Automotive: Stainless steel seam strips for exhaust systems, structural reinforcements, and interior trim.
