Stainless Steel Pipes


Stainless Steel Round Pipes
Formula: (outer diameter – wall thickness) × wall thickness (mm) × length (m) × 0.02491
E.g.: 114mm (outer diameter) × 4mm (wall thickness) × 6m (length)
Calculation: (114-4) × 4 × 6 × 0.02491 = 83.70 (kg)
* For 316, 316L, 310S, 309S, etc., ratio=0.02507

 

Stainless Steel Rectangle Pipes
Formula: [(edge length + side width) × 2 /3.14- thickness] × thickness (mm) × length (m) × 0.02491
E.g.: 100mm (edge length) × 50mm (side width) × 5mm (thickness) × 6m (long)
Calculation: [(100+50)×2/3.14-5] ×5×6×0.02491=67.66 (kg)

 

Stainless Steel Square Pipes
Formula: (side width × 4/3.14- thickness) × thickness × length (m) × 0.02491
E.g.: 50mm (side width) × 5mm (thickness) × 6m (long)
Calculation: (50×4/3.14-5) ×5×6×0.02491 = 43.86kg

 

Stainless Steel Sheets/Plates


Formula: length (m) × width (m) × thickness (mm) × 7.93 
E.g.: 6m (length) × 1.51m (width) × 9.75mm (thickness)
Calculation: 6 × 1.51 × 9.75 × 7.93 = 700.50kg

 

Stainless Steel Bars


Stainless Steel Round Bars
Formula: Dia(mm)×Dia(mm)×Length(m)×0.00623
E.g.: Φ20mm(Dia.)×6m (Length)
Calculation: 20 × 20 × 6 × 0.00623 = 14.952kg
*For 400 series stainless steel, ratio=0.00609

 

Stainless Steel Square Bars
Formula: side width (mm) × side width (mm) × length (m) × 0.00793
E.g.: 50mm (side width) × 6m (length)
Calculation: 50 × 50 × 6 × 0.00793 = 118.95 (kg)

 

Stainless Steel Flat Bars
Formula: side width (mm) × thickness (mm) × length (m) × 0.00793
E.g.: 50mm (side width) × 5.0mm (thickness) × 6m (length)
Calculation: 50 × 5 × 6 × 0.00793 = 11.895 (kg)

 

Stainless Steel Hexagon Bars
Formula: dia* (mm) × dia* (mm) × length (m) × 0.00686
E.g.: 50mm (diagonal) × 6m (length)
Calculation: 50 × 50 × 6 × 0.00686 = 103.5 (kg)
*dia. means diameter between two adjacent side width.

 

Stainless Steel Angle Bars

- Stainless Steel Equal-leg Angle Bars
Formula: (side width ×2 – thickness) ×thickness ×length(m) ×0.00793
E.g.: 50mm (side width) ×5mm (thickness) ×6m (length)
Calculation: (50×2-5) ×5×6×0.00793 = 22.60 (kg)

 

- Stainless Steel Unequal-leg Angle Bars
Formula: (side width + side width – thickness) ×thickness ×length(m) ×0.00793
E.g.: 100mm(side width) × 80mm (side width) × 8 (thickness) × 6m (long)
Calculation: (100+80-8) × 8 × 6 × 0.00793 = 65.47 (kg)

 

Density (g/cm3) Stainless Steel Grade
7.93 201, 202, 301, 302, 304, 304L, 305, 321
7.98 309S, 310S, 316Ti, 316, 316L, 347
7.75 405, 410, 420
