Alloy 20 / 20Cb3 Pipes & Tubes

Accurate Metals & Alloys is one of the top leading pipe manufacturers and exporter of high nickel alloy pipe flanges and fittings. where we supply an Alloy 20 which is an austenitic SS that offers some of the best properties and other features.

The grade delivers high resistance to corrosion, pitting resistance, and great strength at high temperatures and strength. The grade has a balanced chemical composition that helps in delivering the best performance even in the cryogenic temperature.

Whereas, Alloy Cb3 is an austenitic SS having excellent resistance to strong acids such as sulfuric and phosphoric acids. The grade exhibits great resistance to stress corrosion, general corrosion, pitting resistance to chloride environment, high strength, great reliability, and easy fabricability are some of the properties.

Also, the grade has a balanced chemical composition such as carbon, silicon, manganese, phosphorus, and silicon that aims to offer high tensile strength, great yield strength, and easy elongation to the pipes and tubes.

These pipes are resistant to corrosion, pitting, highly suitable for fabrications, stronger resistance to corrosion cracking, and good resistance to acids like nitric or phosphorous acid.

Accurate Metals & Alloys is the manufacturer, supplier, and stockiest of the very good quality Alloy 20 Pipes and Tubes. This is normally used in the industries for piping joining.

We are making these pipes and tubes available to the buyers at various standards, specifications, sizes, lengths, forms, and types. It is provided to the clients at custom-made specifications as per the demands made by the clients with all set industry test reports and certifications.

Alloy 20 is also termed as carpenter 20 chromium, iron, and nickel-based austenitic alloy that is developed for greater resistance to acid attacks particularly sulfuric acid. The superalloy is having very good resistance to general corrosion, crevice corrosion, and pitting in the chemicals that are containing sulfuric, phosphoric, and nitric acid.

Also, it is containing niobium for stabilization against sensitization and resultant intergranular corrosion.

The carpenter 20 is combining very good resistance to corrosion resistance with elevated mechanical properties and good fabrication properties. Though it was developed for use in sulfuric acid related industries, it is today an extensive range of industries like food, chemical, plastic, etc. In addition to it, this is also used in the mixing tanks, piping, etc.
