In Delhi, India, Harshita Stainless is a top producer and supplier of 304I stainless steel tubing, offering premium stainless steel products for commercial and industrial applications. 304I tubing is extensively utilised in chemical processing, food and beverage, and architectural applications due to its exceptional corrosion resistance, weldability, and durability. Harshita Stainless ensures accurate dimensions and long-lasting performance by using premium raw materials and cutting-edge technology in the production of this tubing. The company is a reliable source for stainless steel tubing needs because of its dedication to upholding strict quality standards, offering customised sizes, and providing prompt service both in India and abroad.
In order to improve its weldability and corrosion resistance, stainless steel 304I tubing, a low-carbon version of 304, normally has a reduced carbon content of ≤ 0.03%, 18–20% chromium, and 8–10.5% nickel. With an elongation of up to 40%, this austenitic stainless steel has a yield strength of 205 MPa and a tensile strength of about 515 MPa. It is perfect for fluid transportation and sanitary settings due to its mechanical stability, formability, and resistance to intergranular corrosion following welding. Reliable performance in a range of conditions is ensured by the tubing’s ability to maintain its integrity at both high and low temperatures.
