Pratik Pipe & Fittings is a well-known name in the industry, with the reputation as one of the leading manufacturers, suppliers, stockists, and exporters of high-quality Stainless Steel 321H Tubes in India. The tubes are made to function at their best in corrosive and high-temperature conditions, making them the preferred choice for industrial use. SS 321H is a high-carbon version of the grade 321 stainless steel, which has been formulated to provide more strength and resistance to intergranular corrosion, especially in cases where the steel has to be kept at high temperatures for extended periods of time.
Our SS 321H Tubes are in great demand in the petrochemical, oil and gas, power generation, heat exchangers, chemical processing, and the aerospace industry due to their exceptional mechanical properties as well as thermal stability. The addition of titanium in the alloy does not permit carbide precipitation, which gives exceptional oxidation and scaling resistance even at temperatures up to 900°C (1652°F). This makes SS 321H perfect for use where high weldability, durability, and toughness are essential under extreme conditions.
We provide SS 321H tubes in various thickness, size, and specifications to meet the different needs of our clients. From seamless, welded, to custom-made, all the products are subject to rigorous quality checks to ensure international standards such as ASTM A213, ASTM A312, and ASTM A269. We maintain quality through the use of the finest quality raw materials and the most modern manufacturing techniques, so that every tube meets the best industry standards.
Being a reputed stockist and exporter of Stainless Steel 321H Tubes, we ensure that timely deliveries are provided across India as well as internationally, catering to the urgent as well as heavy demand with maximum efficiency. Our focus on customer satisfaction, affordable prices, and adherence to stringent quality control standards has earned us a strong reputation in the domestic as well as international markets.
