• A2-70 (AISI 304) – 18 % Cr / 8 % Ni, general-purpose corrosion resistance
• A4-70 / A4-80 (AISI 316 / 316L) – 2–3 % Mo added for superior chloride resistance
• Duplex 2205 or 904L available on request for extreme environments
• Tensile strength: 700 MPa (A2-70) – 800 MPa (A4-80)
• Proof load: ≥ 450 MPa (A2-70 bolt) / ≥ 450 MPa (A2-70 nut)
• Temperature range: –196 °C to +800 °C (304) / +870 °C (316)
• Non-magnetic austenitic structure; slight magnetism possible after cold forming
• Self-colour, pickled & passivated per ASTM A967 – bright, contamination-free surface
• Optional mirror polish (Ra ≤ 0.4 µm) or electropolish for food/pharma hygiene
