Known for its outstanding machinability and resistance to corrosion, Dhruv Metals, a reputable manufacturer and supplier of premium stainless steel 416 hollow bars, is based in Hyderabad, India. These hollow bars are made specifically for high-speed machining and structural applications, and their precision, durability, and consistency are guaranteed by the use of advanced manufacturing techniques. For the unique needs of industries like general fabrication, mechanical engineering, and automotive, Dhruv Metals provides stainless steel 416 hollow bars in a range of sizes and specifications. The business provides dependable solutions for both domestic and foreign clients, placing a high priority on quality assurance and customer satisfaction.
Iron and chromium (12–14%) make up the majority of stainless steel 416 hollow bars, with sulphur (0.15–0.35%) added to improve machinability. Manganese, silicon, phosphorus, and carbon are present in trace amounts (~0.15%) in this martensitic grade. Mechanically, it provides a 15% elongation, a 275 MPa yield strength, and a 550–700 MPa tensile strength. After heat treatment, 416 stainless steel exhibits exceptional hardness and moderate corrosion resistance. With an 85% machinability rating (as opposed to free-machining carbon steel), it is perfect for parts that need to be produced quickly and with precise tolerances.

Applications requiring good strength, moderate corrosion resistance, and exceptional machinability frequently use stainless steel 416 hollow bars. They are employed in the production of fasteners, gears, and shafts in the automotive sector. They are used in the production of bushings, spacers, and couplings in machinery and mechanical parts where precise machining and tight tolerances are crucial. These bars are used in the aerospace and defence industries for parts that need to be precise in their dimensions and strong. 416 hollow bars are also utilised in food-grade mechanical components, pumps, and hydraulic systems in mildly corrosive environments. Their machining simplicity lowers fabrication costs and time.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
