SUS304 Stainless Steel Strip Cold Rolled 2B 0.1–3.0mm Thickness – Precision Cut Without Burr
Overview
SUS304 stainless steel strip, cold rolled with a 2B surface finish and available in thicknesses ranging from 0.1 mm to 3.0 mm, is one of the most widely used austenitic stainless steel products in industrial and commercial applications. Renowned for its excellent corrosion resistance, formability, weldability, and aesthetic appeal, SUS304 (equivalent to AISI 304 or EN 1.4301) serves as the benchmark material across sectors such as electronics, automotive, medical devices, food processing, architecture, and precision engineering.
Our precision-cut SUS304 stainless steel strips are manufactured under strict quality control standards to ensure zero burr edges, consistent dimensional tolerances, and superior surface integrity—critical for high-precision assembly and automated production lines.
Key Features & Benefits
- Material Grade: SUS304 (JIS), AISI 304, EN 1.4301
- Surface Finish: 2B (standard mill finish – smooth, semi-bright, suitable for further polishing)
- Thickness Range: 0.1 mm to 3.0 mm (customizable within range)
- Width Options: 5 mm to 600+ mm (slit-to-width per customer specification)
- Edge Quality: Precision slitting with no burrs, ideal for sensitive applications
- Tolerance Control: ±0.005 mm on thickness (for thin gauges <0.5 mm), ±0.02 mm for thicker strips
- Certifications: ISO 9001, RoHS compliant, Material Test Reports (MTR/EN 10204 3.1) available
- Packaging: Anti-rust paper, plastic film, wooden pallets – moisture-proof and coil-protected
This product is especially valued in industries where cleanliness, reliability, and repeatability are non-negotiable—such as semiconductor manufacturing, surgical instruments, battery components, and sensor housings.
Chemical Composition (Per JIS G4305)
| Element | Content (%) – Max/Min |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Chromium (Cr) | 18.0 – 20.0 |
| Nickel (Ni) | 8.0 – 10.5 |
| Iron (Fe) | Balance |
This balanced composition ensures optimal austenitic structure, delivering high ductility, non-magnetic properties (in annealed condition), and resistance to oxidation and organic acids.
Mechanical Properties (Typical, Annealed Condition)
| Property | Value |
|---|---|
| Tensile Strength | 515–690 MPa |
| Yield Strength (0.2% offset) | ≥ 205 MPa |
| Elongation | ≥ 40% |
| Hardness (HV) | 150–200 |
| Density | 7.93 g/cm³ |
| Melting Point | 1400–1450°C |
These properties make SUS304 strips highly suitable for deep drawing, bending, stamping, and laser cutting without cracking or work hardening issues—especially when processed with proper tooling.
Surface Finish: What Is 2B?
The 2B finish is achieved through cold rolling, heat treatment, pickling, and a final light skin-pass rolling. It offers:
- A uniform, matte-silver appearance
- Better flatness and smoother surface than No.1 or 2D finishes
- Excellent base for additional polishing (e.g., to BA, 8K, or brushed finishes)
- Ideal for applications requiring both functionality and visual appeal
Unlike abrasive finishes (e.g., No.4), 2B minimizes surface defects that could harbor contaminants—making it food-grade and medical-device compliant when paired with proper cleaning protocols.
Precision Cutting Without Burrs: Why It Matters
In high-speed automation or micro-component fabrication, even microscopic burrs can cause:
- Assembly jams
- Electrical shorts (in battery tabs or connectors)
- Contamination in cleanrooms
- Reduced fatigue life in dynamic parts
Our advanced tungsten-carbide slitting lines and post-processing deburring systems ensure edge smoothness down to Ra ≤ 0.8 µm, verified by optical profilometry. Every coil undergoes 100% edge inspection before shipment.
Common Applications
