H1: 304 Stainless Steel Plate Weight Chart by Thickness

Intro

304 stainless steel plate is widely used for food machinery, architectural cladding, chemical tanks and general fabrication. For procurement, quotation, container loading and cost calculation, accurate weight data by thickness is essential for metal traders, fabricators and procurement teams.

This article shares the industry‑standard 304 / 304L weight formula, complete thickness‑weight tables, unit conversion and key FAQs. Calculations adopt standard density 7.93 g/cm³ (7930 kg/m³). LSI keywords: 304 stainless steel sheet weight calculator, SS304 plate weight per m², 4×8 ft stainless steel sheet weight, theoretical weight of 304 plate.

H2: 304 Stainless Steel Weight Calculation Formula

Weight (kg) = Thickness(mm) × Width(m) × Length(m) × 7.93 Weight per m² (kg/m²) = Thickness(mm) × 7.93

Example: 2.0 mm, 4×8 ft sheet (1.219 m × 2.438 m) 2.0 × 1.219 × 2.438 ×7.93 = 47.1 kg per sheet

Note: Values are theoretical. Actual weight varies due to mill thickness tolerance.

H2: Calculate for Other Sheet Sizes

Multiply kg/m² value by actual sheet area(m²):

• 1000×2000 mm: Weight = Thickness(mm) × 1 × 2 ×7.93
• 1500×3000 mm: Weight = Thickness(mm) ×1.5 ×3 ×7.93
• 5ft×10ft(1524×3048 mm): Weight = Thickness(mm) ×1.524 ×3.048 ×7.93

H2: Theoretical vs Actual Weight

Deviations come from these factors:

1. Mill tolerance: Cold‑rolled and hot‑rolled plates have nominal‑thickness deviation per ASTM A240.
2. Grade difference: 316L density 7.98 g/cm³; 430 density 7.75 g/cm³. Do not apply this chart to other grades.
3. Surface finish: HL, No.4, BA brushing removes minimal material, negligible for bulk orders.
4. Pattern plate: Checkered anti‑slip plates cannot use flat‑plate weight data.

Business tip: Clarify theoretical weight or actual weighing in purchase contracts.

H2: Practical Application Checklist

• Quotation: Use kg/m² for custom‑cut plates; use 4×8 ft sheet weight for standard sizes.
• Logistics: Sum total weight for container payload calculation.
• Inventory & Invoicing: Cross‑check supplier weight against theoretical figures.
• Cutting processing: Estimate raw material consumption and cutting loss.

H2: FAQ (Featured Snippet Optimized)

Q1: What density for 304 stainless steel weight calculation?

7.93 g/cm³, the global standard for 304 / 304L theoretical weight.

Q2: Can I use this chart for 316L?

No. 316L density is 7.98 g/cm³, which yields higher weight values.

Q3: Why actual weight differs from chart data?

Mill thickness tolerance is the primary cause; hot‑rolled plates show larger deviation. Polishing creates minor weight loss.

Q4: Weight of 1.5 mm 4×8 ft 304 sheet?

35.4 kg (theoretical).

Q5: Convert stainless steel gauge to mm?

‑16 gauge ≈1.52 mm ‑18 gauge ≈1.21 mm ‑20 gauge ≈0.91 mm Convert gauge to mm then look‑up weight in above tables.

H2: Common Mistakes to Avoid

1. Apply 7.93 coefficient to 316L /430, leading to wrong weight and price.
2. Treat theoretical weight as exact physical weight for high‑precision contracts.
3. Use flat‑plate data for checkered plates.
4. Mix units of mm, inch, foot and meter in calculation.

H2: Conclusion

This chart provides theoretical weight per m² and for popular 4×8 ft sheets. Combined with the formula, you can quickly calculate weights for custom dimensions for quotation, logistics and inventory management.

Remember these are theoretical values. Mill tolerance, material grade and surface treatment cause real‑world deviation. Confirm weighing terms with your supplier before bulk orders.
