Harsh Metalloys is a reputable manufacturer and supplier of Stainless Steel 304 Tubing, proudly based in Mumbai, India. SS 304 is the go-to choice for many, being the most widely used austenitic stainless steel grade, celebrated for its outstanding corrosion resistance, formability, and strength. We offer our SS 304 tubes in both seamless and welded options, all crafted to meet international standards like ASTM A213, ASTM A269, and ASTM A249. These tubes find their place in various industries, including food and beverage, pharmaceuticals, petrochemicals, heat exchangers, and architectural structures, providing a durable and dependable solution for a range of fluid and structural needs.
Stainless Steel 304 Tubing generally consists of 18–20% chromium and 8–10.5% nickel, along with trace amounts of carbon, manganese, silicon, and phosphorus. It boasts a tensile strength ranging from 515–750 MPa, a yield strength of about 205 MPa, and can elongate up to 40%. While the tubing is non-magnetic in its annealed state, it may acquire slight magnetism after cold working. SS 304 tubes excel in resisting oxidation, atmospheric corrosion, and a variety of chemicals, while also offering good weldability, cleanliness, and the ability to handle pressure effectively.
