This paper study the electrochemical behavior of the AISI 321 stainless steel in a H{sub 3}BO{sub 3} Solution contaminated with chlorides and its susceptibility to Intergranular Corrosion.Electrochemical prediction diagrams of the stainless steels AISI 321 and 12X18H10T (sovietic) sensitized (600 Centigrade, 3 h.) were compared.
Type 321 is an austenitic stainless steel stabilized by additions of titanium to reduce or prevent carbide precipitation during welding and in service at 800/1650ºF (430/900ºC.) The titanium addition also improves high temperature properties. The grade has good resistance to corrosion and oxidation and good creep strength.
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. For dimensional stability: Stress relieve at 205 to 480 °C (400 to 900 °F) …
AISI 321 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 321 is the AISI designation for this material. S32100 is the UNS number. Additionally, the British Standard (BS) designation is 321S12. The properties of AISI 321 stainless steel include two common variations.
Mechanical testing of the AISI 321 corrosion resistant austenitic steel for contact gigacycle fatigue has been conducted with the application of a new method of contact fatigue testing with ultrasonic frequency of loading according to a pulsing impact "plane-to-plane" contact scheme.

The AISI 321 is an austenitic stainless steel which contains Ti as stabilizing element. This material can be selected for high temperatures services due to its high creep and intergranular corrosion resistance. However there is little information in literature regarding the hot deformation characteristics of AISI 321 steel. Nkhoma et al. [22
AISI 321 stabilized austenitic stainless steel pipes commonly preferred in refinery applications have been welded by the TIG welding process both with and without the use of purging gas. As purging gases, Ar, N{sub 2}, Ar + N{sub 2} and N{sub 2} + 10% H{sub 2} were used, respectively. The aim of this investigation is to detect the effect of
An AISI 321 stainless steel has been developed based on the conventional 18Cr-8Ni alloy system with microstructure stabilization by the titanium (Ti) addition for avoidance of the formation of harmful Cr-rich carbides at grain boundaries and respective intergranular corrosion as well as other undesired intermetallic phases [[1], [2], [3], …
AISI 321 has a face-centered cubic (FCC) structure [4] with low stacking fault Phase maps (Fig. 3b, e) revealed the martensitic transformation of the parent aus-tenitic phase with more fraction of BCC ά-martensite in specimens compressed at low strain rate. This isquitein agreement with the X-ray diffraction result in Fig. 2c.
Abstract. Titanium-stabilized AISI 321 material (UNS S32100) is generally preferred in the pressure vessel industry as it is not sensitive to intergranular corrosion. In critical applications, the fatigue behavior of weld seams is among the most stringent requirements. The microstructural characteristics and fatigue performance double-side …
