Home > Duplex Steel > Duplex Steel Hydraulic Fittings
These Duplex Steel Hydraulic Fittings are crafted from a well-balanced austenite-ferrite microstructure that’s enriched with chromium, nickel, molybdenum, and nitrogen. This unique composition grants them excellent resistance to corrosion, stress cracking, and wear. On the mechanical side, these fittings showcase high tensile and yield strength, outstanding toughness, and reliable fatigue performance, even in high-pressure and low-temperature scenarios. They are engineered to endure intense hydraulic pressures, vibrations, and mechanical stress, ensuring a leak-proof and long-lasting operation. The blend of chemical and mechanical properties makes Duplex Steel Hydraulic Fittings the go-to choice for critical hydraulic systems in tough industrial environments.
