Steel Sales Co is an establishment initiated in Mumbai with the practice of manufacturing and exporting Stainless Steel 321. We are associated with the huge industrial steel tycoons through whom we distribute these Stainless Steel 321H Flanges too. We are also occupied with being one of the well-known stockists of Stainless Steel 321 Flanges in the city. We are completely fine with customizing these Stainless Steel 321H Flanges for our patrons according to their specifications and requisitions.
The Stainless Steel 321 Flanges that we devise are embellished with elements that have superior chemical significance. When these elements are transformed into one chemical structure, they provide the SS 321 grade with an immense number of mechanical properties that differentiate the SS 321H Flanges from the other stainless steel grade flanges. In the chemical composition of the SS 321H grade, they have stabilized versions of the austenitic stainless steel alloys. These are stabilized by the element of titanium present in their elemental structure. These SS 321 Flanges possess a good amount of corrosion resistance caused in the most general aspects. Although these SS 321H Flanges exhibit an extremely great resistance against the intergranular corrosion that occurred due to the exposure the elevated temperatures during the process of chromium carbide precipitation, about 427OC – 816OC. Meanwhile, the SS 321 grade defends the oxidation even at 816OC. The Stainless Steel 304 alloy has the best and the most mechanical properties but the stress rupture and creep properties of the SS 321H alloy surpass the quality of the SS 304 alloy too. These Stainless Steel 321H Flanges function well and display a good amount of strength in cryogenic temperatures.
The applications to which these Stainless Streel 321H Flanges are fabricated are quite vast and varied. But the basic areas and industries where these SS 321 Flanges can be applied are the expansion joints, refinery piping networks, underground water management, waste management systems, and many other chemical factories.
To assure our clients of our product quality of these Stainless Steel 321H Flanges, we carried out a few tests on the S 321 Flanges. The tests that were performed are the hardness test, flange test, positive material identification test, intergranular corrosion test, flattening test, macro test, micro test, and all the other minute chemical and mechanical testing.
