Steel Properties

Physical and mechanical properties of different steel grades and types.

Density Values

Carbon Steel
7850 kg/m³ (0.284 lb/in³)
Most common structural steel. Used for beams, columns, and general construction.
Stainless Steel
7930 kg/m³ (0.287 lb/in³)
Corrosion-resistant steel with chromium content. Higher density than carbon steel.
Cast Iron
7750 kg/m³ (0.280 lb/in³)
High carbon iron alloy. Brittle but good in compression.
Tool Steel
8000 kg/m³ (0.289 lb/in³)
High-carbon steel for making tools. Hardened and tempered.

Mechanical Properties

Yield Strength (Fy)
36-100 ksi (250-690 MPa)
Stress at which material begins to deform plastically. Varies by grade.
Ultimate Tensile Strength
58-150 ksi (400-1035 MPa)
Maximum stress material can withstand before fracture.
Modulus of Elasticity
29,000 ksi (200 GPa)
Stiffness of steel. Used in deflection calculations.
Poisson's Ratio
0.30
Ratio of lateral strain to axial strain under stress.

Frequently Asked Questions

  • How accurate are these weight calculations? Calculations are based on standard steel density (7850 kg/m³) and are accurate to within 1-2% for standard grades.
  • What's the difference between I-beam and H-beam? I-beams have tapered flanges, H-beams have parallel flanges. Both are calculated similarly.
  • Why use different steel densities? Different steel alloys have different densities. Stainless steel is denser than carbon steel due to alloying elements.
  • How do I convert between weight units? 1 kg = 2.205 lbs, 1 ton (metric) = 1000 kg = 2204.6 lbs, 1 ton (US) = 2000 lbs.
  • What about steel plates? Steel plate weight = Length × Width × Thickness × Density. Use the plate calculator for accurate results.
  • How do I estimate costs? Multiply total weight by current steel price per unit weight. Prices vary by grade, quantity, and market conditions.
  • What's the standard length for structural steel? Common lengths are 20', 40', and 60' for beams. Custom lengths available but may cost more.
  • Do I need to account for connections? For rough estimates, add 5-10% for bolts, welds, and connection hardware weight.
