The property of 321 stainless steel and 347 stainless steel is similar in most cases, the 321 stainless steel is a kind of titanium – stabilization of 18/8 austenitic stainless steel (304), a small amount of titanium makes it in carbide precipitation temperature range, that's 425-850℃, not appear intergranular corrosion after heating, with good
While corrosion of thin walled tubes is well addressed by SS347, thicker walled pressure vessels that operate above 643 C ( 1100) may have an issue with "stress releif" cracking if the alloy was stabilized with Niobium. In the case where the wall thickness exceeds 16 mm and the operating temp exc eeds 643 C then Ti stabilized alloys may be
Stainless Steel Round Bar/Rod 347 is normally used in natural gas/petroleum/oil, aerospace, thermal, and industrial applications. 347 stainless maintains its strength and corrosion resistance even over the course of repeated heating and cooling. 347 round bar/rod stock is available in full size and custom cut lengths.
rkg (Mechanical) (OP) 11 Mar 05 13:01. Thermal stabilization of stabilized grades of aust. SS (SS347/SS321) and associated welds is increasingly being specified (which means heating to 815-900 deg. C followed by cooling in air). 1.What advantages does stabilization have?
SS 347 Seamless tubes are the products made using the molten steel grade of 347 over a piercing rod. These seamless pipes are hollow tubes, and they are more substantial compared with other forms. Stainless steel seamless tubes are widely applicable in industries and domestic purposes due to its mechanical and chemical properties.

NACE MR0175 part3 tables may also be helpful. SS 316L is not enough to resist your corrosive environmeent as soon as chloride ions and oxygen are present at quite "high" temperature (200F) for SS 316L. SS 904L is better but probably not good enough in your chloride H2S O2 service.
347 is an austenitic stainless steel that is melted as AOD melt type. This is a stabalized version of 304 stainless to help improve intergranular corrosion resistance. This alloy is similar to 321 stainless except it uses niobium to stabilize the carbon instead of titanium.
Similar to SS321, stainless steel 347 (SS347) is an austenitic stainless steel with deliberate addition of tantalum (Ta) and niobium (Nb) to the basic stainless steel 304 (SS304). The Nb+Ta addition reduces the sensitization of carbide precipitation during welding process which also improves its resistance to intergranular corrosion.
AISI 321 stainless steel (SS321) is basically type 304 with the addition of titanium (Ti), which stabilizes carbides against sensitization to prevent intergranular precipitation of chromium carbide when the steel is heated to a temperature within the sensitization range (such as during welding). 321H is to obtain the best creep strength and cree...
