Metcore Alloys are a manufacturers, suppliers, stockists, and exporters of Stainless Steel 304H Flanges in various forms, wherein the steel alloy contains at least 10.5% chromium by mass. These Stainless Steel 304H Flanges are Slip On, Threaded, Weld Neck, Blind, and other types manufactured for particular uses and performances.
Our working ability has given a reputation to our Stainless Steel 304H Slip On Flanges due to their superior corrosion resistance levels for services related to food handling and cutlery. Its service properties are not easily corroded by water, unlike ordinary steel elements that rust or stain. At the same time, however, our Stainless Steel 304H Weld Neck Flanges are not completely 'stainless' in low oxygen levels, environments having a high salinity percentage, and poor air circulation.
We are leading exporters and stockists of a wide array of Stainless Steel ASTM A182 304H Flanges such as Slip On, Weld Neck, Socket Weld, Blind, Orifice, Spectacle Blank, Screwed/Threaded, Reducing and Ring Type Joint Flanges. Our stainless steel 304H blind flanges are meant for those applications where properties of steel are required along with superior resistance to corrosion. The greater chromium content in our Stainless Steel UNS S 30409 Socket Weld Flanges, unlike carbon steel, is responsible for their resistance against rust and corrosion.
A protecting film of chromium oxide prevents further corrosion by blocking oxygen diffusion to the metal surface in our Stainless Steel 304H Ring Joint Type Flanges. Some of the applications of our Stainless Steel 304H Nippo Flanges are in clean rooms and such other environments for medical and pharmaceutical applications. These SS 304H Spacer Flanges should, therefore, be cooled from the anneal temperature with the maximum practical rate to prevent precipitation of chromium carbides.
We pride ourselves for being in the fore towards manufacturing and supplying high-quality Stainless Steel 304H Flanges that stand tall amidst harshest of atmospheric conditions on corrosion resistance. Our SS 304H Weld Neck Flanges have resistance to food and beverages industries in organic and inorganic chemicals in moderately oxidizing to moderately reducing environments.
Due to the presence of high chromium and nickel in our ASTM A182 SS 304H Blind Flanges, their performance becomes optimum in acetic and nitric acid environments, hence that makes them vital for industries like petroleum refining and chemical processing. Our SS 304H Threaded Flanges are extremely resistant to reducing atmospheres, while the SS 304H Lap Joint Flanges have excellent corrosion resistance in ordinary atmospheric conditions.
Properties like hardness and strength are enhanced in Stainless Steel 304H Ring Joint Type Flanges due to cold working. Annealing after heavy welding sections may be required for our SS 304H Orifice Flanges, though generally not necessary for all Stainless Steel 304H Spectacle Blind Flanges. Our Stainless Steel 304H Slip On Raised Flanges can be welded by all fusion and resistance welding processes. Stainless Steel 304H Blind Raised Flanges are utilized in food industries because this material is more resistance to corrosion.
