Product Details
Duplex Grub Screw M12 x 30 🔹 Chemical Composition (UNS S32760 / Super Duplex 32760) Chromium: ~24–26% → Provides high resistance to corrosion and oxidation. Nickel: ~6–8% → Improves toughness and structural stability. Molybdenum: ~3–4% → Enhances resistance against pitting and crevice corrosion. Copper & Tungsten additions → Extra resistance to aggressive chloride and acidic environments. Low Carbon → Prevents carbide precipitation and intergranular corrosion. 🔹 Mechanical Properties Tensile Strength: ~750–880 MPa → Very high strength compared to austenitic steels. Yield Strength: ≥550 MPa → Reliable in high-load applications. Hardness: ~250 HB max → Balanced hardness for wear resistance. Excellent fatigue strength and impact toughness even at sub-zero temperatures. Dual-phase microstructure (Austenite + Ferrite) → Ensures superior stress corrosion cracking resistance. 🔹 Dimensional Specifications (DIN 916 Standard) Type: Hexagon Socket Set Screw with Cone Point. Size Range: Typically available from M3 to M36. Thread: Metric coarse thread as per ISO standards. Tolerance: Threads produced with precision for accurate tightening. Lengths: Short, medium, and long lengths as per DIN 916 specifications. 🔹 Applications Offshore and marine industries → Pumps, valves, and subsea fastenings. Chemical and petrochemical plants → Equipment exposed to acids, chlorides, and harsh chemicals. Oil & Gas industry → Heat exchangers, pipeline flanges, and fastening of critical equipment. Desalination plants → High chloride resistance makes it ideal for seawater service. Power generation & infrastructure → Used in turbine assemblies and heavy-duty fastening applications. 🔹 Why Aanuraj Fasteners Pvt Ltd?
