Mechanical properties

304 stainless steel cannot be heat treated-instead it can be strengthened by cold working. It is weakest in the annealed condition, and is strongest in the full-hard condition. The tensile yield strength ranges from 210 to 1,050 MPa (30,000 to 153,000 psi).

The density is 7,900 kg/m³ (0.286 lb/cu in), and its modulus of elasticity ranges from 183 to 200 GPa (26.6×10⁶ to 29.0×10⁶ psi)
