SS347 is a chromium-stabilized austenitic stainless steel that offers good corrosion resistance. The composition of SS 347 Filler Wires is similar to 304 and 316, except for the addition of nickel and columbium. These additives give the stainless steel more excellent oxidation resistance. They also help to reduce the risk of intergranular ...

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 …

ABSTRACT. A new optimized post weld heat treatment (PWHT) of 347 type stainless steels has been developed and laboratory tested up to 1562°F (850°C) to address the needs of the petrochemical industry in stretching the upper operating temperature limits beyond 950°F (510°C). Experimentation focused on 347H, 347LN, and 16Crl …

Hardening. Grade 347H stainless steel is unresponsive to heat treatment. The hardness and strength of the steel can be increased through cold working. Stainless steels are high-alloy steels which have high corrosion resistance than other steels owing to the presence of large amounts of chromium in the range of 4 to 30%.

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 ...

In this study, a multi-layered wall was fabricated using Wire Arc Additive Manufacturing (WAAM) process using ER321 filler wire to evaluate the static and dynamic mechanical properties.

The metallurgy of the unit is predominately SS347 and SS316. The areas I'm mainly concerned about are the wash water injection point which is at elevated temperatures (~250F) and dead ends. Wash water is injected in large excess so there is no chance of drying out. Heat tracing maintains temperature above water dew point in the hotter parts …

we are trying to weld a bush (SS347) and flange (SS304) together in TIG welding, observing a crack, can any one suggest to how to overcome this problem. You will need some 347 rod. Are you sure your flange is not 303 that will cause your cracking for sure. I cannot see why 347 and 304 would be a problem. Only 347 and 303.
