Adinox Overseas is a well reputed, supplier and exporter of high quality Sanicro 28 Fasteners produced to the strict industrial requirements. They are made of a high-stainless austenitic stainless steel, known as Sanicro 28 (or UNS N08028) and are designed to resist corrosion in the most aggressive settings. Our Sanicro 28 Fastener was designed to meet the ASTM B468 specifications and B472 specifications; hence it is suitable in phosphoric acid production, seawater systems, chemical processing, and oil and gas industries.
Having great amount of chromium (26-28%), nickel (30-32%) and molybdenum (3-4%), Sanicro 28 Fasteners offers excellent resistance against oxidising and reducing agents. Its excellent operating capability under chloride containing conditions aids in preventing stress corrosion cracking and is therefore a suitable material in offshore platforms and heat exchangers and piping systems. Moreover, they ensure good mechanical stability at a high temperature resulting in high service life and low maintenance costs.
Sanicro 28 is generally referred to as Alloy 28 which is a universal standard name, and due to its versatility and great resistance to pitting and crevice corrosion, Alloy 28 is very much favored. In Adinox Overseas, we provide Sanicro 28 Fasteners such as bolts, nuts, washers, and studs, screws and those which have been customized and subject to intensive test conditions in terms of quality parameters. The production of each fastener is carried out with the application of the newest technology and all fasteners are checked according to tensile strength, hardness, dimension accuracy, surface finish and are checked in accordance to international norms.
Adinox Overseas is committed to delivering fasteners that provide reliable fastening solutions in aggressive and high-heat environments. Our dedication to quality, traceability, and customer satisfaction has made us a preferred supplier in both domestic and international markets. We also provide material traceability reports, third-party inspection certificates, mill test certifications, and compliance documents for all our ASTM A479 253 MA Fasteners. Our fasteners offer not just mechanical integrity but also cost-effective performance in demanding conditions.
