Metinox Overseas is a leading manufacturer, supplier, stockist, and exporter of Stainless Steel 304H Welded Tubing in Mumbai, India. SS 304H Welded Tubing stands out as one of the most sought-after tubes in the industry. Comprised of elements such as carbon, manganese, silicon, phosphorus, sulfur, chromium, and nickel, these grades boast a chemical composition that grants them a higher elongation range of 40%. Notably, they exhibit appropriate levels of hardness according to both Rockwell and Brinell standards. Moreover, their higher density confers remarkable resistance to pressure.
The SS S30409 Welded Tube is renowned for its array of captivating attributes, including seamless weldability, flexibility, durability, formability, and cost-effectiveness. In numerous scenarios, 304H emerges as a superior choice among ferritic stainless steel tubes, owing to its exceptional anti-rusting properties surpassing many commonly used grades. These specifications adhere to rigorous standards set forth by UNS, BS, JIS, EN, among others, with dimension standards originating from ASTM A312/ ASME SA312. Notably, they exhibit characteristics of both ferritic and austenitic steel.
