sa 240 tp 304 or sa 240 gr 304l density

 

 

 

Density of SA 240 TP 304 and SA 240 GR 304L

The density of both SA 240 TP 304 and SA 240 GR 304L is 8.00 g/cm³ (or 8000 kg/m³), as specified by ASME SA 240, ASTM A240, and industry standards. This value is consistent across both grades due to their nearly identical chemical compositions, with the only significant difference being the carbon content (≤0.08% for 304 vs. ≤0.03% for 304L), which has a negligible effect on density.

Significance of Density

• Weight Calculations: At 8.00 g/cm³, a 1m x 1m x 3mm plate (e.g., plat SS 304 3mm) weighs approximately 24 kg, critical for structural design and cost estimation.
• Comparison: Identical to other austenitic grades (e.g., SA 240 GR 316L), higher than aluminum (~2.7 g/cm³), and slightly higher than ferritic stainless steels (e.g., SA 240 GR 430, ~7.7 g/cm³).
• Applications: Supports lightweight designs in food processing, chemical, and architectural applications, where corrosion resistance is prioritized.

Gangsteel’s sa 240 gr 304 and sa 240 gr 304l plates ensure consistent density for accurate design calculations.

 

Chemical Composition Comparison

The chemical compositions of SA 240 TP 304 and SA 240 GR 304L are nearly identical, except for carbon content, contributing to their identical density:

Element	SA 240 TP 304 (%)	SA 240 GR 304L (%)
Carbon (C)	0.00 - 0.08	0.00 - 0.03
Manganese (Mn)	0.00 - 2.00	0.00 - 2.00
Silicon (Si)	0.00 - 0.75	0.00 - 0.75
Phosphorus (P)	0.00 - 0.045	0.00 - 0.045
Sulfur (S)	0.00 - 0.030	0.00 - 0.030
Chromium (Cr)	18.00 - 20.00	18.00 - 20.00
Nickel (Ni)	8.00 - 10.50	8.00 - 12.00
Nitrogen (N)	0.00 - 0.10	0.00 - 0.10
Iron (Fe)	Balance	Balance

• Carbon: Lower in 304L (≤0.03%) for enhanced weldability, with minimal impact on density.
• Chromium and Nickel: Ensure corrosion resistance and non-magnetic properties, contributing to the 8.00 g/cm³ density.

Mechanical Properties Comparison

The mechanical properties differ slightly due to carbon content, but density remains unaffected:

Property	SA 240 TP 304 (Min)	SA 240 GR 304L (Min)	Notes
Tensile Strength (MPa)	515	485	304 stronger due to higher carbon
Yield Strength (0.2% Offset, MPa)	205	170	304L sacrifices strength for weldability
Elongation (A5, 50 mm)	40%	40%	Both highly ductile
Hardness (Brinell)	≤ 201 HB	≤ 201 HB	Similar machinability

Corrosion Resistance and Weldability

Both grades offer excellent corrosion resistance in:

• Atmospheric conditions, freshwater, and mild acids (food-grade).
• General environments, outperforming SS204 vs SS 304 due to higher nickel content.

Key differences:

• SA 240 TP 304: Good weldability with ER308 fillers, but higher carbon (≤0.08%) may cause sensitization in welded zones.
• SA 240 GR 304L: Superior weldability due to low carbon (≤0.03%), minimizing sensitization, ideal for welded applications like SA 240 GR 304 pipe.

Applications

SA 240 TP 304 and SA 240 GR 304L are used in:

• Food Processing: Tanks and equipment (e.g., plat stainless 304) for hygiene.
• Chemical Industry: Vessels and SA 240 GR 304 pipe for mild corrosives.
• Architecture: Structural panels like plate 2 mm SUS 304.
• Medical Devices: Non-magnetic components leveraging non-magnetic properties.
