Aug 20, 2019 · The role of grain size and strain rate on the corrosion behavior of plastically-deformed Ti-stabilized austenitic stainless steel (AISI 321) in saline media was investigated. The as-received ...
Nov 23, 2020 · The most common of these stabilized grades are types 321 and 347. Type 321 contains a minimum of 5 × (C% + N%) titanium, and type 347 a minimum of 8 × C% niobium. Nitrogen must be considered when titanium is used as a stabilizer, not because the precipitation of chromium nitride is a problem in austenitic steels, but because titanium nitride ...

The corrosion rate of 310 stainless steel (310SS) in the original and purified NaCl-KCl-MgCl 2 was 1581 μm/y and 298 μm/y using immersion test at 700 °C for 500 h under Ar atmosphere, respectively [[14], [15], [16]]. The corrosion depth of 316 L stainless steel in purified NaCl-KCl-MgCl 2 under Ar attained 150 μm at 700 °C for 500 h [17].
Aug 18, 2023 · Austenitic stainless steels are versatile and popular materials, known for their corrosion resistance, high-temperature strength, and suitability for the fabrication process. Austenitic stainless steel is widely used across most higher-specification industrial and domestic applications.
Recommended annealing temperature for TP321 and 321 wrought stainless steel: 1040 °C (1900 °F); Minimum 1095 °C (2000 °F) for cold-worked 321H and 1050 °C (1095 °F) for hot-finished 321H. Stress-relieving treatments. For dimensional stability: Stress relieve at 205 to 480 °C (400 to 900 °F) and then slow cool (usual time, 4 h per inch ...
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800–1500°F (427– 816°C). The alloy resists oxidation to 1500°F
Aug 5, 2021 · AISI 321 stainless steel has excellent resistance to intergranular corrosion and is generally used in nuclear power reactor vessels and other components. The as-cast and wrought structures are quite different in hot workability, so physical simulation, electron back-scatter diffraction, and hot processing maps were used to study the mechanical behavior and microstructure evolution of as-cast ...
