Super Duplex Thermowell

Super Duplex 32750 Thermowells, Super Duplex Flanged Thermowell and Super Duplex Straight Thermowell. Super Duplex stainless steels are becoming more common. They are being offered by all the major stainless steel mills for a number of reasons: Higher strength leading to weight saving Greater corrosion resistance particularly stress corrosion cracking Better price stability Super Duplex Thermowell, also referred to as austenitic-ferritic stainless steels, are a family of grades having around equal proportions of austenite and ferrite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Duplex steels offer high resistance to uniform and local corrosion because of their high content of nitrogen, chromium and molybdenum. Duplex stainless steels have good weldability. The austenite and ferrite micro-structure of duplex stainless steel has a number of benefits over austenitic stainless steel. Much improved since their introduction in the 1930’s, the low nickel content of duplex stainless steels makes them a more cost effective option. The use of nitrogen as a replacement for expensive nickel gives several advantages, including enhanced tensile properties and greater resistance to pitting and crevice corrosion, and they are twice the strength of austenitic stainless steels. Their lighter weight also makes duplex stainless steels cheaper to transport and assemble.
