When it comes to Duplex Needle Valves, they’re crafted from duplex stainless steel, which typically contains around 22–25% chromium, 5–7% nickel, 3–4% molybdenum, along with small amounts of nitrogen, manganese, and iron. This unique dual-phase microstructure (austenite and ferrite) gives them remarkable strength and corrosion resistance. These valves boast high tensile strength (usually over 620 MPa), solid yield strength (about 450 MPa), and impressive elongation and toughness, making them perfect for high-pressure situations. Their ability to resist pitting, crevice corrosion, and stress corrosion cracking makes them a go-to choice for demanding industrial applications.
