What is 321 stainless steel pipe?
321 stainless steel is an austenitic stainless steel known for its exceptional high-temperature stress rupture strength and creep resistance. Compared to 304 stainless steel, it offers enhanced mechanical properties under high-temperature conditions. Stabilized with titanium (Ti), 321 stainless steel prevents intergranular corrosion when exposed to temperatures ranging from 425-850°C. This makes it an excellent choice for applications requiring oxidation resistance, high strength, and phase stability in high-temperature environments up to 900°C. This article will briefly introduce what is 321 stainless steel pipe.

Can stainless steel welded pipes be made into thick-walled pipes?
Many people mistakenly believe that stainless steel welded pipes are synonymous with thin-walled pipes, assuming that their wall thickness is greatly limited and that thick pipes cannot be produced. This misconception primarily arises from the longstanding emphasis on the ease and cost-effectiveness of manufacturing thin-walled stainless steel welded pipes compared to seamless pipes under the same compressive strength. However, with advancements in technology, stainless steel welded pipes have overcome this limitation, and thick-walled stainless steel welded pipes are now widely used across various industries.
