304 stainless steel coil is the most commonly used austenitic stainless steel, corresponding to AISI 304 / EN 1.4301 / SUS304. It features excellent corrosion resistance, formability, weldability and heat resistance, widely used in both civil and industrial fields.
5.Chemical Composition (typical, wt%) 6.Standard Tensile Properties (ASTM A240 / EN 10088-2) Hardness (Annealed State)
Brinell Hardness (HBW): ≤ 201
Rockwell Hardness (HRB): ≤ 92
Vickers Hardness (HV): 150 - 200
Key Physical & Mechanical Notes
Condition: The above values are for soft/annealed (solution treated) coils (standard supply state: 1010-1150°C quench).
Cold-Rolled / Hardened State:
Tensile/Yield Strength: 550 - 800 MPa (increases with cold work)
Elongation: 10 - 30% (decreases with hardening)
Hardness: 220 - 300 HV (higher for full hard)
Magnetism: Non-magnetic when annealed; slightly magnetic after cold work.
Density: 7.93 g/cm³
Impact Toughness: Good (excellent at cryogenic temps, no brittle transition down to ~-196°C).
7. Common Grades Equivalent
ASTM: 304 (UNS S30400)
EN: 1.4301 (X5CrNi18-10)
JIS: SUS304
GB: 06Cr19Ni10 (S30408)
Surface & Finish
Common surface types for stainless steel coil:
2B Finish: cold rolled, annealed, pickled, skin passed - general purpose
BA Finish: bright annealed, mirror-like luster
No.1, No.4, HL (brushed), mirror polish, etc.
Key Features
Good corrosion resistance in atmospheric, water and mild chemical environments
Excellent formability: bending, deep drawing, stamping, rolling
Good weldability without preheating
Usable temperature range: -196°C ~ 800°C
Non-magnetic in annealed condition8.Chemical Composition & Mechanical Properties of 304, 316, 321 Stainless Steel Sheets
(Standard: ASTM A240 / ASME SA240, fully annealed condition, all values in mass percentage %)
1. Chemical Composition (Element Limit, %) Key Composition Differences
304: Classic 18-8 Cr-Ni stainless steel, no Mo / Ti; universal corrosion resistance.
316: Added Molybdenum (Mo); superior chloride/seawater & acid corrosion resistance.
321: Stabilized with Titanium (Ti); eliminates chromium carbide precipitation, resists intergranular corrosion at high temperatures.

9. Mechanical Properties (Annealed State, ASTM Standard)
10. Performance Summary & Core Advantages
304
Most cost-effective general-purpose grade.
Good atmospheric, mild acid/alkali corrosion resistance; excellent weldability & formability.
Widely used for decoration, kitchenware, food equipment, ordinary structural parts.
316
Mo-alloyed grade; outstanding resistance to chloride corrosion, seawater, chemical media, pitting & crevice corrosion.
Slightly higher high-temperature resistance than 304; ideal for marine, chemical, pharmaceutical, medical equipment.
321
Ti-stabilized heat-resistant grade.
Excellent anti-intergranular corrosion after welding & long-term high-temperature exposure; best creep resistance among the three.
Mainly for boiler components, exhaust pipes, heat exchangers, high-temperature pipelines & thermal equipment.

11. Supplementary Note (Common Low-Carbon Variant)
304L: C ≤ 0.03% (low-carbon 304, better weldability, less intergranular corrosion)
316L: C ≤ 0.03% (low-carbon 316, most widely used industrial corrosion-resistant grad
