Notes:1. Composition values are in weight % (balance Fe).
2. Mechanical properties are typical values (may vary with heat treatment).
3. Austenitic grades (304, 316) are non-magnetic, corrosion-resistant, and ductile.
4. Martensitic grades (410, 420) are hardenable by heat treatment.
5. Ferritic grades (430) are magnetic with moderate corrosion resistance.
6. Duplex grades (2205, 2507) offer high strength and corrosion resistance.
