Most common austenitic stainless steel. Used in food processing, kitchen equipment, and general-purpose applications.
Marine-grade stainless steel with molybdenum. Better corrosion resistance, used in chemical, marine, and pharmaceutical industries.
Low-nickel austenitic steel. Cost-effective alternative to 304 for less demanding applications.
SS 304 has a density of 8.0 g/cm³ (8000 kg/m³). This is about 2% denser than mild steel (7.85 g/cm³). For weight calculations, multiply the MS weight by 8.0/7.85 = 1.019.
SS plate weight = Length × Width × Thickness × density / 1,000,000 (all dimensions in mm). Example: 1000×500×3mm SS 304 plate weighs 1000 × 500 × 3 × 8.0 / 1000000 = 12.0 kg.
SS 316 contains 2-3% molybdenum which provides better corrosion resistance, especially against chlorides. SS 316 is slightly denser (8.027 vs 8.0 g/cm³) and more expensive. Choose 316 for marine, chemical, or high-corrosion environments.
SS pipe weight per metre = (OD − WT) × WT × π × density / 1000, where OD is outer diameter and WT is wall thickness in mm. Use the correct density for the SS grade.
Yes, SS 202 (7.86 g/cm³) is about 1.75% lighter than SS 304 (8.0 g/cm³). For the same dimensions, SS 202 will weigh slightly less.
