With its headquarters located in Chennai, India, Vinit Stainless is a reputable manufacturer and supplier of stainless steel 304H tubing. Vinit Stainless is well-known for its dedication to accuracy and quality, and it offers high-performance tubing solutions made for applications requiring high pressure and temperature. High carbon austenitic stainless steel, which is used to make SS 304H tubing, is perfect for heat-resistant settings like refineries, petrochemical plants, and power plants. International standards for strength, durability, and corrosion resistance are met by these tubes, which are manufactured using sophisticated techniques and stringent quality control. Vinit Stainless is a reputable brand in the stainless steel sector because it guarantees prompt delivery and top-notch customer support.
A high-carbon variant of 304 stainless steel, 304H tubing has 0.04–0.10% carbon, 8–10.5% nickel, and 18–20% chromium. Strength and creep resistance at higher temperatures are improved by the higher carbon content. It has good elongation and toughness, as well as a tensile strength of about 515 MPa and a yield strength of about 205 MPa. Because it can withstand extended exposure to high temperatures without losing its structural integrity, SS 304H tubing is appropriate for applications involving pressure. Long-term performance in demanding service environments is ensured by its exceptional corrosion resistance, weldability, and resistance to high-temperature oxidation.
