SS 321 / 321H Spool Fittings Manufacturer, Supplier In Mumbai India

Alpha Overseas is well known in the industry for its production and distribution of SS 321/321H Spool Fittings. The stabilized variant of stainless steel 304 is stainless steel 321. To provide type 321 protection from intergranular corrosion that may occur following heat treatment, the 18/8 mixture of chromium and nickel is tempered with titanium. It is guarded against temperatures of 800 to 1500° F. The metal has a high degree of tensile strength and is resistant to many types of corrosion, especially those caused by wet environments. Heavy welding components and constantly changing conditions both find a use for type 321 materials.

However, the titanium addition restricts the working of 321 when used. Due to the metal's non-consumable nature, some welding processes are not advised. Beyond this, stainless steel 321, which doesn't need to be annealed after being welded and exhibits toughness over a wide temperature range, has good forming properties. The higher-carbon variant of stainless steel 321 is stainless steel 321. To prevent intergranular corrosion, niobium is added to 321H to stabilize it. Having more carbon than type 321 allows it to endure greater temperatures. The metal cannot be toughened through heat treatment, despite 321H exhibiting the same welding and forming properties as type 321. It is used when type 321 cannot tolerate high temperatures, usually above 1000° F. The pre-built components of a piping system are pipe spools. Pipe spools are manufactured before being employed in the piping system and are used to store pipes, flanges, and fittings. Pipe spools are pre-shaped to make putting the sections together easier with hoists, gauges, and other tools. Long pipes are joined together by pipe spools having flanges at the ends so they can be fastened together with flanges that match. Before the concrete is poured, these connectors are inserted into the structure's walls. Because this system must endure the weight and stress of the structure, it must be properly aligned before concrete is poured.

What specifically are SS 321/321H Spool Fittings?
Stainless steel 321 is a stabilised form of stainless steel 304. The 18/8 chromium-nickel alloy is tempered with titanium to protect type 321 against intergranular corrosion that may occur after heat treatment. It is resistant to temperatures ranging from 800 to 1500° F. The metal has a high tensile strength and is resistant to a wide range of corrosion, particularly that induced by moist environments. Type 321 materials are used for heavy welding components as well as continually changing environments.
