Features of SS 321/SS 321H Tubes-
These stainless steel tubes are not only manufactured in high quality but they offer various exceptional features and properties. The features include high tensile strength, corrosion resistance, pitting cracking corrosion, formability, weldability, and long service life. These tubes can also perform best in the extreme hot and cold conditions without getting damaged.
Well, talking about the grade 321 and 321H both the grade are stabilized stainless steel grade where the only difference is the high amount of carbon content. Stainless steel 321 is a stabilized stainless steel; the alloy consists of nickel and chromium content that is tempered with titanium that offers intergranular corrosion after heat treatment.
On the other hand, stainless steel 321H is having high carbon content and is stabilized with the addition of niobium so as to resist intergranular corrosion. The alloy is able to withstand in high temperature because of the elevated carbon content. However, alloy 321 cannot be hardened by heat treatment but get hardened by cold treatment making it easy to weld.
The SS 321/SS 321H Tubes are fully inspected and tested and packed in premium quality of packaging material which in turn helps to prevent damages until the product is delivered to its respective customers or client.
