High-Quality 304 Stainless Steel Strip – Corrosion-Resistant & Durable for Industrial Applications
Product Overview
Our high-quality 304 stainless steel strip is engineered to deliver exceptional performance in demanding industrial environments. Made from premium-grade AISI 304 (UNS S30400)—also known as SUS304 (JIS) or 1.4301 (EN)—this cold-rolled strip combines outstanding corrosion resistance, mechanical strength, and formability in a versatile, thin-gauge format. Available in thicknesses from 0.1 mm to 3.0 mm with a smooth 2B surface finish, it is ideal for precision manufacturing across sectors including automotive, electronics, medical devices, food processing, and renewable energy.
Every coil undergoes stringent quality control to ensure dimensional accuracy, edge integrity, and long-term durability—making it a trusted choice for engineers and OEMs worldwide.
Why Choose 304 Stainless Steel?
Grade 304 is the most widely used austenitic stainless steel due to its balanced composition of 18% chromium and 8% nickel, which provides:
- Superior resistance to oxidation, organic acids, and atmospheric corrosion
- Excellent weldability and formability without post-weld annealing
- Non-magnetic properties in the annealed condition (ideal for sensitive electronics)
- Compliance with FDA, NSF, and EU hygiene standards for food and medical use
Whether exposed to humid coastal air, chemical cleaners, or high-temperature processes, 304 stainless steel maintains structural integrity and aesthetic finish over time.
Key Product Features
| Feature | Specification |
|---|---|
| Material Grade | AISI 304 / SUS304 / EN 1.4301 |
| Form | Cold-rolled strip or coil |
| Thickness Range | 0.1 mm – 3.0 mm (custom tolerances available) |
| Width Options | 5 mm – 650 mm (precision slit-to-width) |
| Surface Finish | 2B (standard); optional BA, No.4, or brushed |
| Edge Quality | Precision-slit, burr-free, Ra ≤ 0.8 µm |
| Tolerance (Thickness) | ±0.005 mm (for 0.1–0.5 mm), ±0.02 mm (for 0.5–3.0 mm) |
| Standards | ASTM A666, JIS G4305, EN 10088-2 |
| Certifications | ISO 9001, RoHS, REACH, Material Test Report (MTR/EN 10204 3.1) |
| Packaging | VCI anti-rust paper + PE film + wooden pallet (export-ready) |
Chemical Composition (ASTM A240)
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Silicon (Si) | ≤ 0.75 |
| Chromium (Cr) | 18.0 – 20.0 |
| Nickel (Ni) | 8.0 – 10.5 |
| Iron (Fe) | Balance |
This composition ensures a stable austenitic microstructure, enabling excellent ductility (elongation ≥ 40%) and resistance to intergranular corrosion.
Mechanical Properties (Annealed Condition)
| Property | Typical Value |
|---|---|
| Tensile Strength | 515–690 MPa |
| Yield Strength (0.2% offset) | ≥ 205 MPa |
| Elongation | ≥ 40% |
| Hardness (Rockwell B) | 70–85 HRB |
| Density | 7.93 g/cm³ |
| Melting Range | 1400–1450°C |
These properties support deep drawing, bending, stamping, and laser cutting—without cracking or excessive work hardening—when proper tooling and lubrication are used.
The 2B Surface Finish Advantage
The 2B finish is the industry-standard mill finish for cold-rolled stainless steel, achieved through:
- Cold rolling
- Annealing in a controlled atmosphere
- Pickling to remove scale
- Light skin-pass rolling for smoothness
Benefits of 2B finish:
- Uniform, semi-bright matte appearance
- Excellent flatness and surface cleanliness
- Ideal base for secondary finishes (e.g., polishing, coating)
- Resists fingerprint smudging better than bright-annealed (BA) finishes
- Meets hygiene requirements for food-contact surfaces
Unlike rougher finishes (e.g., No.1 or 2D), 2B minimizes micro-pits that could trap contaminants—critical in cleanroom or sterile environments.
Burr-Free Precision Cutting: Critical for Modern Manufacturing
In automated assembly lines, robotics, or micro-component production, even microscopic burrs can cause:
- Equipment jams or sensor malfunctions
- Electrical arcing in battery tabs or connectors
- Contamination in pharmaceutical or semiconductor processes
- Reduced fatigue life in dynamic components
Our state-of-the-art precision slitting line uses diamond-coated blades and real-time laser monitoring to deliver clean, smooth edges with zero micro-burrs. Every batch is inspected using optical profilometry to guarantee edge quality.
Industry Applications
| Industry | Typical Uses |
|---|---|
| Electronics | Battery current collectors, EMI/RFI shielding, flexible PCB supports, spring contacts |
| Medical | Surgical instrument components, implant housings, diagnostic device frames |
| Automotive | Fuel system parts, sensor brackets, exhaust gaskets, EV battery interconnects |

Frequently Asked Questions (FAQ)
Q: Is 304 stainless steel suitable for marine environments?
A: While 304 offers good general corrosion resistance, 316 stainless steel is recommended for prolonged saltwater exposure due to its molybdenum content.

A: Absolutely. All shipments include chemical composition reports and mechanical test data.
Q: What’s the difference between 304 and 304L?
A: 304L has lower carbon content (≤0.03%) to prevent carbide precipitation during welding—ideal for heavy welded structures. For most strip applications, standard 304 is sufficient.
