Product Description

304 Stainless Steel Coil - Comprehensive Specification & Application Guide
304 stainless steel coil is the most widely used grade in austenitic stainless steel series, also known as 18/8 stainless steel in the industry (containing 18% chromium and 8% nickel). It corresponds to the following international standards: UNS S30400 (USA), JIS SUS304 (Japan), DIN 1.4301 (Europe), and GB 06Cr19Ni10 (China).

1. Core Chemical Composition (ASTM A240 Standard)

Element	Content Range	Function
Carbon (C)	≤0.08%	Balances strength and corrosion resistance
Chromium (Cr)	18.00-20.00%	Forms a passive film to provide basic corrosion resistance
Nickel (Ni)	8.00-10.50%	Stabilizes the austenitic structure and enhances toughness and corrosion resistance
Manganese (Mn)	≤2.00%	Assists in stabilizing austenite and improves hot workability
Silicon (Si)	≤1.00%	Acts as a deoxidizer and improves high-temperature oxidation resistance
Phosphorus (P)	≤0.045%	Controls impurities to avoid brittleness
Sulfur (S)	≤0.030%	Controls impurities and enhances machinability

2. Key Mechanical Properties (Cold-Rolled/Annealed Condition)

Performance Index	Value	Unit
Tensile Strength	≥515	MPa
Yield Strength	≥205	MPa
Elongation	≥40	%
Hardness (Brinell)	≤201	HB
Density	7.93	g/cm³
Temperature Resistance Range	-196ºC ~ 800ºC	ºC

3. Common Specification Parameters (Core for Foreign Trade Quotation)

Category	Specification Range	Remarks
Thickness	0.2mm ~ 8.0mm	Cold-rolled: 0.2-3.0mm; Hot-rolled: 3.0-8.0mm
Width	10mm ~ 1550mm	Regular widths: 1219mm / 1500mm
Inner Diameter	508mm / 610mm	International standard size, convenient for transportation and processing
Outer Diameter	Calculated based on weight	Usually 1000-2500mm
Weight	1-25 tons/coil	Regular orders: MOQ 5 tons
Surface Finish	2B / BA / No.1 / HL	2B (cold-rolled matte, general purpose); BA (bright annealed, food-grade); No.1 (hot-rolled pickled, industrial use); HL (brushed, decorative use)

4. Core Characteristics & Advantages
Excellent Corrosion Resistance: Performs well in fresh water, seawater, weak acid and alkali environments, suitable for food contact scenarios.
Good Processability: Superior stamping, bending and welding performance, with no heat treatment hardening phenomenon.
Outstanding Toughness: Maintains good toughness at low temperatures (-196ºC), suitable for extreme environments.
Attractive & Easy to Clean: Smooth surface, easy to clean, compliant with hygiene standards.
Wide Applicability: High versatility, can replace various ordinary steel grades, reducing material selection costs.

5. International Standard Equivalent Chart

Standard System	Corresponding Grade	Application Scenarios
ASTM (USA)	304 (UNS S30400)	Chemical industry, food processing equipment
JIS (Japan)	SUS304	Electronics, precision instruments
DIN (Germany)	1.4301	Architectural decoration, medical devices
GB (China)	06Cr19Ni10 (S30408)	Pressure vessels, environmental protection equipment
EN (Europe)	X5CrNi18-10	General industry, pipeline systems

6. Typical Application Fields
Food Processing: Storage tanks, conveying pipelines, kitchen utensils, food machinery.
Chemical Equipment: Reactors, heat exchangers, corrosion-resistant pipelines.
Architectural Decoration: Curtain walls, handrails, elevator panels, decorative plates.
Medical Devices: Surgical instruments, medical device casings.
Electronics & Electrical Appliances: Home appliance parts, electronic component housings.
Water Treatment: Seawater desalination equipment, sewage treatment systems.
Automotive Industry: Exhaust system components, decorative parts.
