Alloy 347 is a columbium (niobium)/tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular …
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. This improved corrosion resistance allows this grade to be used in service at much …
ASTM A312 TP 347 Stainless Steel Seamless Pipes is a tantalum/columbium stabilized austenitic nickel-chromium product that was formed to offer an 18-8 type of alloy in the company of an enhanced inter-granular-corrosion resistance.
347 stainless steel is a columbium/tantalum stabilized austenitic chromium-nickel stainless steel. Type 347 has excellent intergranular corrosion resistance and oxidation resistance. at high temperatures. This material is stabilized against chromium carbide formation by the addition of columbium and tantalum.
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 ...
Types 321 and 347 stainless steels are the alloys most commonly thermally stabilized, but these alloys are also susceptible to weld and HAZ cracking problems during these heat treatment procedures, i.e., reheat cracking and grain boundary liquation cracking (mechanism covered in a previous article).
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.
