Top Super Duplex Stainless Steel Thermowell Manufacturing Company in Chennai

Super Duplex Stainless Steel thermowells are generally made from UNS S32750 or S32760 grades, featuring around 25% chromium, 7% nickel, and 3–4% molybdenum, along with controlled nitrogen content. This well-balanced austenitic-ferritic microstructure results in remarkable mechanical properties, such as high tensile strength, excellent yield strength, and outstanding fatigue resistance. The material is highly resistant to pitting, crevice corrosion, and stress corrosion cracking, even in environments rich in chlorides. These characteristics ensure reliability and structural integrity, even under extreme pressure and temperature conditions.
