Kencotube is one of the leading manufacturing houses for high quality Duplex Steel Olets Fittings, which allows to be matched for corrosion resistance with the austenitic and ferritic steel grades. Duplex Steel Outlet Fittings must be emphasised that this table is only a guide to material selection. Duplex Steel Weldolet Fittings is always important to assess the suitability of a particular with a full knowledge of the corrosive environment. Duplex Steel Threadolets Fittings are known to be prone to SCC, where the advantage of high strength immediately becomes a disadvantage when considering formability and machinability. Meanwhile, the high strength in these fittings also comes with lower ductility than austenitic grades. Due to their high chromium content, Duplex Steel Sockolets Fittings offer excellent corrosion resistance in many media.
Duplex Steel Latrolets Fittings has very limited use in hydrochloric acid because of the risk of uniform and localised corrosion. The best steels to use for this purpose are the high nickel austenitic Duplex Steel Elbolets Fittings such as the six percent of Mo grades. The resistance to pitting and crevice corrosion in these Duplex Steel Olet Pipe Fittings increases with the content of chromium, molybdenum and nitrogen in the steel. There is no single measure of corrosion resistance in Duplex Steel Outlet Pipe Fittings, but it is convenient to use the Pitting Resistance Equivalent Number (PREN) as a means of ranking the grades. Meanwhile, Kencotube also offer our clients at possible rates of these products.
