347 stainless steel is a columbium/tantalum stabilized austenitic chromium-nickel stainless steel. This material is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium, columbium-tantalum carbides precipitate within the grains instead of 347 Stainless Steel UNS S34700 UlbrichType 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation.
347 Alloy Description. Alloy 347 is a stabilized stainless steel similar to type 304 with an addition of Columbium and Tantalum. Columbium stabilizes this alloy making it immune to chromium carbide precipitation. Alloy 347 is recommended for welded applications that can not tolerate a post anneal.

Alloy 347 is generally used where corrosive conditions are severe, such as aircraft exhaust stacks, manifolds and ring collectors. Type 347 is also used for heavy welded assemblies which cannot be annealed after welding or where the operating conditions cause exposure within the temperature range between 426.67° to 815.55°F. Core 347/4550 EN 1.4550, ASTM TYPE 347H / UNS S34709 Core 347/4550 has excellent weldability and is suitable for the full range of conventional welding methods (like MMA, MIG, MAG, TIG, SAW, LBW, or RSW), except gas welding. Core 347/4550 has about 50% higher thermal expansion and lower heat conductivity compared to carbon steels. Elevated temperature physical properties of stainless steelsElevated temperature modulii of elasticity and coefficients of expansion for stainless steels specified in BS EN 10088-1. The table below is based on the reference data presented in BS EN 10088-1. Only a sample of the information is shown for the most commonly used stainless steel types. These are grouped using 'AISI' steel types.

Alloy 347 is a stabilized austenitic stainless steel, similar to type 304, but alloyed with Niobium (Columbium) for use in applications involving continuous or intermittent service at 800-1500°F (427-816°C). 347 stainless has excellent resistance to oxidation, even surpassing that of 321 in strong oxidizing conditions. Welding of Austenitic Stainless Steel - Part 2 - TWIAustenitic stainless steels have a low coefficient of thermal conductivity, approximately 1/3rd that of ferritic steel at room temperature and a coefficient of thermal expansion some 30% more than that of a ferritic steel. Higher expansions in a narrower HAZ result in higher residual stresses and more distortion. eFunda:Properties of Stainless Steel AISI Type 347Category :Steel:Class :Stainless steel:Type :Austenitic standard:Common Names :Chromium-Nickel steel:Designations :France:AFNOR Z 6 CNN6 18.10 Germany:DIN
Alloy 347 does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid. Fabrication Data Alloy 347 can be easily welded and processed by standard shop fabrication practices. Machining The cold work hardening rate of 321 makes it less machinable than 410 stainless steel
