Stainless Steel 321 / 321H Instrumentation Accessories Manufacturer

Instrumentation ball valves are made of 321/321H stainless steel alloy, which is an austenitic steel alloy stabilized with 18% chromium and 8% nickel. It also contains titanium, which provides excellent corrosion resistance in general. Compared to other alloys, these valves resist oxidation up to 1500°F and have good stress rupture and creep qualities.

Stainless Steel 321/ 321H Flanges are commonly used in the piping industry since they aid in the connection of two pipes to form a complete piping system. Stainless Steel 321/321H Accessories fulfill ANSI, ASTM, and ASME requirements, as well as domestic and international norms and standards. They are utilized in applications and industries such as the petrochemical industry, chemical processing industry, seawater equipment, and many more where pipe connection is necessary because of their high tensile strength. These 321/ 321H Stainless Steel Condensate Pots are the best because they keep and sustain quality for a long period. There are no flaws in the SS 321/ 321H Welded Tubes. Austenitic chromium-nickel alloy is used to make these tubes. However, titanium is used in the manufacturing of the tubes since it gives them the strength to withstand high temperatures. The tubes are available in a variety of sizes and ranges, making them appropriate for a variety of applications.
