Duplex Stainless Steel Thermowells boast a unique dual-phase microstructure, consisting of about 50% austenite and 50% ferrite, which provides an exceptional blend of strength and corrosion resistance. Their typical composition includes 21–23% chromium, 4.5–6.5% nickel, and 2.5–3.5% molybdenum, ensuring outstanding resistance to chloride-induced corrosion, pitting, and crevice attack. On the mechanical side, they deliver a tensile strength of around 620 MPa, a yield strength of about 450 MPa, and impressive toughness and fatigue resistance. These characteristics guarantee reliable performance even under high pressure, temperature changes, and corrosive conditions, prolonging the life of both the thermowell and the instruments they protect.
