Annealed 304 Stainless Steel Strip in Various Widths and Thicknesses – Excellent Formability and Finish

Product Overview

Our annealed 304 stainless steel strip is precision-engineered for applications demanding superior ductility, surface quality, and dimensional consistency. Produced from high-purity AISI 304 (UNS S30400 / SUS304 / EN 1.4301) and fully annealed after cold rolling, this strip offers unmatched formability, making it ideal for deep drawing, bending, stamping, and intricate shaping processes across industries such as medical devices, consumer electronics, food processing, automotive components, and architectural trim.

Available in thicknesses from 0.1 mm to 3.0 mm and widths from 5 mm to 650 mm, our product line supports both standard and custom specifications—with a smooth 2B finish as standard and optional surface treatments available. Every coil is delivered in a soft-annealed condition, ensuring maximum workability without cracking or springback issues.

Why Choose Annealed 304 Stainless Steel Strip?

Annealing—a controlled heat treatment followed by rapid cooling—relieves internal stresses induced during cold rolling. This process:

Maximizes elongation (>40%) and reduces hardness (70–85 HRB)
Restores non-magnetic properties (critical for sensors and electronics)
Enhances corrosion resistance by homogenizing the microstructure
Improves surface uniformity and eliminates orange peel or stretcher strains

Combined with 304’s inherent 18% chromium / 8% nickel composition, the annealed strip delivers long-term reliability in corrosive, high-hygiene, or high-formability environments.

This balanced chemistry ensures a stable austenitic structure that resists sensitization and maintains performance after forming.

Mechanical Properties (Annealed Condition)

Property	Typical Value
Tensile Strength	515–620 MPa
Yield Strength (0.2% offset)	205–310 MPa
Elongation	≥ 40%
Hardness	70–85 HRB (150–180 HV)
Density	7.93 g/cm³
Melting Range	1400–1450°C

These properties make the material exceptionally suited for deep-drawn parts, complex bends, and high-speed progressive die operations without requiring intermediate annealing.

Surface Finish: The 2B Advantage

The 2B finish is the most widely specified surface for industrial stainless steel due to its:

Smooth, semi-bright, uniform appearance
Excellent flatness and minimal surface defects
Suitability as a base for polishing, coating, or printing
Compliance with hygiene standards (FDA, NSF, EU 1935/2004)

Unlike abrasive finishes (e.g., No.4), 2B avoids directional grain patterns that can trap contaminants—making it ideal for medical instruments, food contact surfaces, and cleanroom components.

Optional finishes:

BA (Bright Annealed): Mirror-like reflectivity for decorative uses
No.4 Brushed: Linear grain for architectural panels
Custom textures: Embossed or matte finishes upon request

Precision Slitting with Burr-Free Edges

Even in the softest temper, poor edge quality can compromise forming or assembly. Our slitting process includes:

Laser-guided alignment for width accuracy (±0.1 mm)
Carbide tooling with adaptive pressure control
Post-slit inspection via high-resolution cameras

Result: Clean, smooth edges with no micro-burrs—essential for automated feeding, laser cutting, and sensitive handling in electronics or medical manufacturing.

Industry Applications

Industry	Common Uses
Medical Devices	Surgical scalpel blades, implant housings, catheter components
Consumer Electronics	Smartphone frames, EMI shields, battery brackets
Food & Beverage	Filler nozzles, conveyor guides, mixing paddles
Automotive	Sensor mounts, fuel system washers, interior trim clips
HVAC & Appliances	Heat exchanger fins, dishwasher racks, control panels
Industrial	Springs, shims, spacers, filtration mesh

The annealed condition ensures these parts can be formed into complex geometries without cracking—even at ultra-thin gauges like 0.15 mm.

Quality Assurance & Traceability

Full heat number traceability from melt to coil
EN 10204 3.1 Material Test Reports with every shipment
In-house testing for chemistry (OES), tensile strength, hardness, and surface roughness
Optional cleanliness certification (per VDA 19 or ISO 16232) for automotive customers

Our production follows ISO 9001:2015 protocols, with real-time SPC (Statistical Process Control) monitoring.

Frequently Asked Questions (FAQ)

Q: What’s the difference between annealed and hard-temper 304 strip?
A: Annealed strip is soft and highly formable; hard-temper (e.g., 1/2H, H) is stronger but less ductile—used for springs or wear parts. For forming, annealed is preferred.

Q: Can I get strips with tighter flatness for laser cutting?
A: Yes—for gauges under 0.5 mm, we offer ≤0.5 I-Unit flatness using tension-leveling lines.

Q: Is annealed 304 magnetic?
A: In the fully annealed state, it is non-magnetic (<5 Gauss). Cold working may induce slight magnetism, but it remains suitable for most electronic applications.

Q: Do you supply material for FDA-compliant food equipment?
A: Yes—our 2B-finish 304 meets FDA 21 CFR 178.3297 and EU 1935/2004 for indirect food contact.
