Stainless Steel 347/347H Tubes

Silver Tubes is a prominent Exporter & Trader of Stainless Steel 347 Tubes / Stainless 347H Tubes, which has slightly improved corrosion resistance in strongly oxidizing environments. Stainless Steel 347 Seamless Tubes is also advantageous for high temperature service because of its good mechanical properties. Stainless Steel 347 Welded Tubes offers higher creep and stress rupture properties than Stainless Steel 304, which might be considered for exposures where sensitization and intergranular corrosion are concerns. Stainless Steel 347 EFW Tubes is a columbium(niobium)/tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance. Stainless Steel 347 ERW Tubes has a slightly improved corrosion resistance over other alloys of stainless steel in strongly oxidizing environments as a result of the addition of columbium (niobium) and tantalum.

Stainless Steel 347H Seamless Tubes is the higher carbon (0.04 – 0.10) version of the alloy. Stainless Steel 347H Welded Tubes was industrialized for improved creep resistance and for advancedpotency at tempabove 1000 Degree F (537 Degree C). Stainless Steel 347H EFW Tubes does not perform well in chloride solutions, even in small concentrations, or in sulphuric acid. Stainless Steel 347H ERW Tubes 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.The high temperature oxidation resistance of SS 347 Tubes is similar to that of SS 304.
