AISI 304 Stainless Steel Bar – Composition & Key Properties
AISI 304 is an austenitic stainless steel composed of 18% chromium and 8% nickel, making it highly resistant to corrosion and oxidation. Its excellent mechanical properties include:
High Tensile Strength: Minimum 515 MPa
Yield Strength: Minimum 205 MPa
Hardness: 58-60 HRC (excellent machinability)
High-Temperature Resistance: Performs well in elevated temperatures
Corrosion Resistance: Resists rust in freshwater, marine, and chemical environments
These properties make AISI 304 bars ideal for demanding applications where strength, durability, and resistance to harsh conditions are critical.
