Stainless Steel 304 Sheet Price Per Kg

SS 304 sheet price starts from ₹200 and goes up to ₹350 per kg in India and $2.50–$6.00 per lb in the US market. Thickness, surface finish, sheet size, and order quantity drive the final cost. A 2B finish sheet costs less than #4 brushed or #8 mirror polish. Contact Sachiya Steel International for the current 304 stainless steel sheet price and volume discounts.

Chemical Composition of 304 Stainless Steel Sheet

ASTM A240 / ASME SA-240 defines the chemical composition of AISI 304 stainless steel sheet as shown below. Chromium at 18% minimum forms the passive oxide film responsible for corrosion resistance. Nickel at 8% minimum stabilises the austenitic microstructure.

Carbon C
Max 0.08%
Manganese Mn
Max 2.00%
Phosphorus P
Max 0.045%
Sulfur S
Max 0.030%
Silicon Si
Max 1.00%
Chromium Cr
18.0 – 20.0%
Nickel Ni
8.0 – 11.0%

Mechanical Properties of 304 Stainless Steel Sheet

ASTM A240 Grade 304 sheet meets these minimum mechanical requirements in the annealed condition. The 35% minimum elongation makes this grade well-suited for bending, deep drawing, roll-forming, and brake-forming operations.

Industrial Applications of 304 Stainless Steel Sheet

Type 304 sheet serves a broad range of industries because of its corrosion resistance, formability, and hygienic surface.

Food Processing and Kitchen Equipment

Commercial sinks, countertops, splashbacks, food prep tables, and brewing vessels all use 304 sheet for its FDA-compliant, non-reactive surface. The 2B finish is standard for food-contact applications.

Architectural and Construction

Wall cladding, elevator panels, column covers, and roofing panels use #4 brushed or #8 mirror finish 304 stainless sheet.

Chemical and Industrial Processing

Tanks, vessels, ducting, and enclosures in mild acid and alkaline process environments rely on the passive chromium oxide film of 304 stainless steel sheet.

Frequently Asked Questions:

What is the Price of 304 Stainless Steel Sheet per kg? +
The price of 304 SS sheet ranges from ₹200–350/kg in India and $2.50–$6.00/lb in the US. Final cost varies with thickness, finish (2B costs less than #8 mirror), sheet size, and order volume.
What Sizes does 304 Stainless Steel Sheet come in? +
Standard 304 stainless steel sheet sizes are 4×8 ft (1219×2438 mm) and 4×10 ft (1219×3048 mm). Thickness ranges from 26 GA (0.46 mm) to 10 GA (3.43 mm). Custom sizes and cut-to-size service are available from Sachiya Steel.
What is the Difference between 304 and 316 Stainless Steel Sheet? +
304 sheet is more cost-effective and sufficient for most indoor and mildly corrosive environments. 316 sheet adds 2–3% molybdenum for superior chloride and pitting resistance. This makes it the better choice for marine, coastal, and high-chloride chemical applications.
What Finishes are Available for 304 Stainless Steel Sheet? +
There are 4 standard finishes. These include 2B mill finish (smooth, matte), #4 brushed (directional satin polish), #8 mirror (highly reflective), and bright annealed (BA). Each finish suits different visual and functional requirements.
How much does a 4×8 Sheet of 304 Stainless Steel Weigh? +
Weight depends on thickness. An 18-gauge (1.2 mm) 4×8 ft sheet weighs approximately 28.6 kg (63 lbs). Use this formula to calculate: Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 8.00.
Can 304 Stainless Steel Sheet be Bent or Formed? +
Yes. The 35% minimum elongation per ASTM A240 allows 304 sheet to be readily bent, roll-formed, and deep drawn. A minimum bend radius of 1× thickness works for thinner gauges.
What ASTM Standard covers 304 Stainless Steel Sheet? +
ASTM A240 / ASME SA-240 is the primary specification for 304 stainless steel sheet, plate, and strip. AMS 5513 covers aerospace-grade 304 sheet in the annealed condition. It can be supplied on request.
Where Can I Buy 304 Stainless Steel Sheet? +
Sachiya Steel International supplies 304 stainless steel sheet in all standard finishes, sizes, and gauges. We provide mill test certificates, ASTM A240 compliance documentation, and cut-to-size services with worldwide shipping.
