Product Description
Astm B704 Incoloy 825 Seamless Stainless Steel Coiled Tubings for SCSSV
Tiptop is specialized in providing alloy steel coiled tube, alloy steel control line, alloy steel continuous tube with have high corrosion resistance and temperature strength.
INCOLOY® alloy 825 (UNS N08825, W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives Alloy 825 tubing great resistance to reducing environments, like those containing sulfuric and phosphoric acids. Aiding resistance to pitting and crevice corrosion is one of the chief benefits of the molybdenum. Resistance to a variety of oxidizing substances such as nitric acid, nitrates, and oxidizing salts comes from the chromium content. Titanium, often with heat treatment, serves to stabilize the alloy against sensitization to inter granular corrosion.
