At MT Stainless Steel, we are proud to present our Alloy 400 Pipes – a seamless innovation in the world of nickel alloys. Specifically designed for geotherm applications, these pipes exhibit superior resistance to a myriad of corrosive elements, including sulfuric and hydrochloric acids. Crafted from Nickel Alloy 400, our seamless pipes stand a cut above the rest with their commendable physical properties. These pipes, boasting a high melting range (1300-1350℃) and density (8.80 g/cm3), are known for their surpassed durability and performance. Manufactured in compliance with the ASTM B161/163, ASTM B 168/B 906 standards, our seamless pipes feature an outer diameter of 6mm-457mm and wall thickness ranging from 0.75mm-20.00mm. At MT Stainless Steel, we adopt advanced cold drawn/cold rolled technology in the production process. Our pipes undergo rigorous testing procedures, including NDT, mechanical tests, metal analysis, and chemical analysis, to ascertain their quality and structural integrity. Our Alloy 400 seamless pipes come with the assurance of ISO, PED, and AD2000 certifications. They are carefully packed in iron cases or woven bags to ensure safe transit and are made available across Europe, Middle East, Southeast Asia, South America, and beyond. As manufacturers and suppliers, we, at MT Stainless Steel, are committed to meeting the needs of our customers in the geotherm industry and beyond. Experience superior performance, durability, and corrosion resistance with our Alloy 400 Nickel Alloy Seamless Pipes.

Features: Nickel alloy 400 has excellent resistance to corrosion by many reducing media such as sulfuric and hydrochloric acids. It is generally more resistant to corrosion by oxidizing media than higher copper alloys. Monel 400 resists pitting and stress corrosion cracking in most fresh and industrial waters. It has good resistance in flowing seawater, but under stagnant conditions, pitting and crevice corrosion is induced. Alloy 400 is probably the most resistant to hydrofluoric acid in all concentrations up to the boiling point, of all engineering alloys. Alloy 400 is notable for its toughness, it does not show embrittlement tendency at cryogenic temperatures. It is work hardenable.

Applications: Chemical process equipment, crude oil stills, gasoline and fresh water tanks, marine engineering equipment, valves, pumps and fasteners.
