Ojas Pipes and Tubes, located in Kolkata, India, is a reliable manufacturer and supplier of Hot Finished Seamless (HFS) Tubing, known for delivering strong and precisely engineered tubing solutions tailored for heavy-duty industrial needs. Our HFS Tubes are crafted by heating and shaping solid billets, which guarantees exceptional dimensional accuracy, strength, and consistent wall thickness. At Ojas, we provide HFS tubing in a variety of carbon steel and alloy steel grades, adhering to standards such as ASTM A106, A53, and EN 10210. These tubes are perfect for structural, mechanical, and high-temperature applications, making them popular in industries like power generation, construction, automotive, and heavy engineering.
HFS Tubing is typically made from either carbon steel or alloy steel, depending on its intended use. The usual compositions feature Carbon (0.18–0.30%), Manganese (0.60–1.65%), and may include optional elements like Molybdenum, Chromium, or Nickel for alloy grades. The mechanical properties usually showcase a tensile strength ranging from 415 to 585 MPa, yield strength between 240 and 355 MPa, and elongation of 20 to 30%, varying by material grade. HFS Tubes are known for their excellent toughness, weldability, and resistance to pressure. The hot finishing process improves the grain structure and surface quality, making them well-suited for high-stress and high-temperature conditions.
