Stainless Steel 347/347H Electropolished Pipes & Tubes

Stockist & Supplier of Stainless Steel 347 / 347H Electropolished Pipes & Tubes

Alloy 347/347H Electropolish Pipes and Tubes, which is a columbium/tantalum stabilized austenitic chromium-nickel alloy. Stainless Steel 347 Electropolish Pipes is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium in Stainless Steel 347 Electropolish Tubes, columbium – tantalum carbides precipitate within the grains instead of forming at the grain boundaries.

Stainless Steel 347H Sanitary Tubes can be successfully welded using most standard arc welding processes, where pre–heating, and post-heating are not required and should be avoided. When a filler Stainless Steel 347H Smooth Finish Pipes is needed, a matching composition rod will provide the best match in thermal expansion properties.

Stainless Steel 347 Sanitary Tubes is non-magnetic and is stabilized by the addition of columbium and tantalum. Stainless Steel 347 Sanitary Pipes should be considered for applications requiring intermittent heating between 800 Degree F (427 Degree C) and 1650 Degree F (899 Degree C) or for welding under conditions which prevent a post-weld anneal. If a matching composition is not available a high nickel filler metal can be used, where these Stainless Steel 347H Smooth Finish Tubes will result in a weld with different thermal expansion properties.

Stainless Steel 347 Smooth Finish Pipes is a stabilized stainless steel that offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 Degree F to 1500 Degree F. 347H Stainless Steel Electropolish Pipes is often utilized in process streams containing chlorides or halides. The addition of molybdenum in 347H Stainless Steel Electropolish Tubes improves general corrosion and chloride pitting resistance.

Stainless Steel 347 Electropolished Tubes is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening. Stainless Steel 347H Inside Polished Pipes resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. Stainless Steel 347H Inside Polished Tubes has excellent resistance to intergranular corrosion in the as-welded condition.
