GENERAL PROPERTIES. Type 321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C). Type 321 is stabilized against chromium carbide formation by the addition of

Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C. Grade 321 is the grade of choice for applications in the temperature
Re: SS 321 vs SS 316L. 01/08/2008 12:09 PM. The molybdenum gives 316 better overall corrosion resistant properties than Grade 321 (similar to 304, with Ti addition to improve temperature property within 800-1500 deg F), particularly higher resistance to pitting and crevice corrosion in chloride environments.
SS 321 / SS 321H. Stainless Steel 321 is the stabilized version of Stainless Steel 304. The 18/8 blend of chromium and nickel is tempered with titanium to give type 321 protection from intergranular corrosion that can occur after heat treatment. It is protected from temperatures ranging from 800 to 1500° F. The metal displays high strength and
This work investigates the cut quality characteristics of SS321 using plasma arc cutting. The SS321 has a wide range of applications such as in chemical storage, exhaust manifolds of automotives and aircraft. The intricate shapes for this material are very difficult to cut using conventional machining process. Hence, plasma arc cutting is used. …
SUS321 and SUS347 are the basic austenitic 18/8 steel (SUS 304) stabilised by Titanium (SUS321) or Niobium (SUS347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature
The tacks should be subsequently grinded or at least be free from crater cracks. 1.4541 in connection with austenitic weld metal and too high heat input the addiction to form heat cracks exists. The addiction to heat cracks can be confined, if the weld metal features a lower content of ferrite (delta ferrite). Contents of ferrite up to 10% have
