Premium-grade stainless steel 347 pipes from Ojas Pipes and Tubes, a reputable manufacturer and supplier with headquarters in Delhi, India, are renowned for their exceptional resistance to corrosion and high temperature strength. Niobium stabilisation gives these pipes exceptional resistance to oxidation and intergranular corrosion. Ojas is dedicated to providing high-quality products that satisfy global standards, meeting the demands of sectors such as power generation, aerospace, and petrochemicals. With its state-of-the-art production facilities, strict quality control, and customer-focused philosophy, Ojas Pipes and Tubes has made a name for itself as a trustworthy supplier of stainless steel piping solutions in both the Indian and international markets.
347 Stainless Steel In order to prevent carbide precipitation during welding and high-temperature exposure, the pipes are stabilised austenitic stainless steel pipes that contain chromium (17–20%), nickel (9–13%), carbon (≤ 0.08%), and niobium (columbium). This alloy retains its strength at high temperatures and provides exceptional resistance to intergranular corrosion. Tensile strength of about 515 MPa, yield strength of about 205 MPa, and elongation of 40% are typical mechanical characteristics. These pipes are perfect for applications needing a long service life and resistance to oxidising and corrosive atmospheres because they maintain their structural integrity in high-stress, high-heat environments.

Because of their improved mechanical stability and resistance to corrosion, stainless steel 347 pipes are frequently utilised in high-temperature and high-stress settings. Heat exchangers, boiler tubes, aircraft exhaust systems, chemical processing apparatus, and refinery pipes are examples of common applications. These pipes are also utilised in the production of furnace and superheater components, as well as in nuclear power plants and maritime settings. They are especially useful in welded structures exposed to high temperatures because of their resistance to intergranular corrosion following welding. Ojas Pipes and Tubes’ Stainless Steel 347 Pipes provide dependable performance in industries where oxidation resistance, strength, and dependability are essential.
