Rupal Metals, located in Delhi, India, has earned a solid reputation as a reliable manufacturer and supplier of stainless steel 303 round bars and rods. They pride themselves on delivering top-notch products that are designed for high machinability and a fantastic surface finish. Known for their precision manufacturing, prompt delivery, and a strong focus on customer service, Rupal Metals ensures that their 303 round bars meet international industry standards. These bars are perfect for high-speed machining tasks where strength and resistance to corrosion are crucial. Rupal Metals has become a go-to supplier across various industries, consistently providing quality and reliable performance in every stainless steel product they offer.
The stainless steel 303 round bars and rods are made up of 17–19% chromium, 8–10% nickel, and a touch of sulfur (0.15–0.35%) to enhance machinability. This type of austenitic stainless steel contains up to 0.15% carbon, along with small amounts of manganese and silicon, and it remains non-magnetic when annealed. It boasts a tensile strength of about 585 MPa, a yield strength of 240 MPa, and an elongation of 35%. While 303 may not resist corrosion as well as 304, it shines in terms of machinability, making it a great choice for complex and high-volume production tasks.
