Stainless Steel 347/347H Seamless Tubes present a distinctive composition, tailored for optimal performance across various industrial applications. These austenitic stainless steel variants, supplied by Metinox Overseas, boast remarkable similarities, differing primarily in carbon content. Notably, SS 347H Seamless Tubing contains higher carbon levels compared to SS 347, imbuing it with enhanced properties.

The inclusion of columbium stabilizes the alloy, furnishing exceptional resistance in strongly oxidizing environments and against corrosion, including intergranular corrosion, even at elevated temperatures ranging approximately from 427 to 816 degrees Celsius. SS 347 exhibits superior corrosion resistance over SS 321 and delivers commendable mechanical properties at high temperatures.
