SS321 is titanium-based austenitic SS with very good resistance to general corrosion. It is having phenomenal resistance ability against corrosion into the carbide precipitation temperature ranges from 427 to 816 deg C. It also maintains oxidation to temperature 816 deg C. Furthermore, it has stress and creep-rupture properties. SS321H is the modification of SS321. This material is developed for improvising creep resistance and also greater strength at the temperature ranging 537 deg C.
The application of SS 321 Welded Pipes and SS 321H Welded Pipes is including petrochemicals, pharmaceuticals, specialty chemicals, chemical processing, pulp & paper industry, oil & gas processing, heat exchangers, textile industry, fertilizers, etc.
There are many product qualities testing done on it so that the quality of these pipes can be very well maintained. Few product tests are including radiography tests, chemical tests, mechanical tests, IGC tests, etc. The test certifications provided to the clients are MTC as per En10203/3.1b etc.
