Alloy 20 information-
Alloy 20 is the austenitic, chromium, nickel, iron-based super alloy with the addition of molybdenum and copper alloy that provides resistance to the hostile atmosphere, crevice corrosion and pitting. It is stabilized with columbium to minimize the carbide precipitation at the time of welding. This alloy appears falling in between both the alloys nickel and stainless steel category as the alloy is having features of both alloys.
The alloy is designed for providing the maximum resistance to the acid attack and it demonstrates very good resistance to stress corrosion at boiling to 20%-40% sulfuric acid. The alloy is also having very good general corrosion resistance ability, stress corrosion cracking and is having excellent mechanical properties at elevated and ambient temperature.
Because of the excellent properties, the product is having become widely popular among the large numbers of industrialists and is used widely in many industrial applications. High tensile strength, anti-corrosiveness, rigid construction, yielding strength, fine surface finishes, good dimensional accuracy, long-lastingness is the properties offered. Moreover withstanding high temperature and resistance to stress corrosion cracking, pitting, oxidation, carburization, crevice corrosion is offered by the product.
Manufacturing of needles and valves-
The production process of the Alloy 20 Needle & gauge valves begins up with the use of high quality of alloy that is sourced from the best market vendors. The alloy before made in use is well tested for assurance of quality so that high quality of product development can be assured. The product is created the same as per set manufacturing norms and raw material quality standards under the strict guidance of professional experts that are having full knowledge of the better quality of product creation.
test certifications- The test certifications offered to the buyers is including mill test certifications as per EN 10204/3.1B, 100% radiography test report, third-party test report, raw material certificate, buyers report.
Documentation- To the buyers, few important documents are offered that is mainly to prove the product quality and its usefulness. Heat treatment chart, commercial invoice, guarantee letter, packaging list, raw material test report, material traceability report, NABL lab test report, fumigation certificate, etc.
Packaging- For safer shipping of Alloy 20 Needle & gauge valves to the buyers, the packaging is recommended into the wooden cases, carton boxes and is also wrapped into the environmental poly bags.
