Virgin engineers are one of the recognized manufacturer, supplier, wholesaler, stockholder and distributor of wider ranges of forged steel valves. Stainless steel 321 / 321H Forged steel valves are designed as per the international and national standard quality of raw materials thus assuring the product to offer high strength and durability. The valves are used manually either through wheel, handle, pedal or lever. The valves are operated automatic that is driven by the changes in the temperature, pressure, flow. We are offering the wide ranges of valves to the buyers that easily fulfill all applications desires. To the national and international buyers, the product ranges are offered at different specifications, work pressure, pressure rating, sizes, end connection, and temperature rating.
Alloy 321 is stainless steel austenitic titanium stabilized alloy that is having very good resistance ability to corrosion. It is possessing resistance to intergranular corrosion after it gets exposed to the temperature ranging 427 Deg C to 816 Deg C in the chromium carbide precipitations. The alloy is resisting oxidation at the temperature 1500 Deg F and is having very high creep and stress rupture properties than other alloys. Also, the alloy possesses very good low-temperature toughness. Alloy 321H is high carbon version of 321 alloys. The alloy is developed for the purpose of enhancing the creep resistance and high strength at the temperature more than 1000 Deg F. Alloy 321 can’t be hardened through the heat treatment and by the cold working technique only. It is welded easily and processed by the technique of standard shop fabrications.
Manufacturing details to know-
The manufacturing of Stainless steel 321 / 321H Forged steel valves are executed with the use of fine quality of raw materials. The used raw material is collected from the best market mills and is tested very well to check the quality of it so that the high quality of product development is assured. The producers are developing the same by using the latest technology and modern tools under the supervision of professional experts. The offered ranges of stainless steel forged valves are done by considering the product quality standards and set norms of manufacturers.
The product is having many good properties to offer that makes it be the ideal choice for many industrial applications. The product properties are high tensile strength, good dimensional accuracy, and fine surface finishes, sturdiness, anti-corrosive body, longevity, durability, etc. Also, it is having the ability to hold high pressure and high temperature. It is resistance to stress corrosion cracking, pitting, oxidation, crevice corrosion, etc.
The product documents offered are like heat treatment chart, quality assurance plan, packaging list, guarantee letter, raw material test report, NABL approved lab test report, material traceability report, etc. The test certifications offered to the buyers are like MTC as per EN 10204/3.1B, third-party test report, buyers report, etc.
During the time of shipping of Stainless steel 321 / 321H Forged steel valves, the packaging is done in wooden cases, carton boxes and wrapped in environmental poly bags.
