Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of high-quality stainless steel products, including Stainless Steel 317L Needle Tubes. Based in India, the company has built a strong reputation for producing precision-engineered tubes that meet stringent international quality standards. Their focus on consistent quality, timely delivery, and customer satisfaction has made them a trusted name in both domestic and global markets.
Stainless Steel 317L Needle Tubes are made from low-carbon, molybdenum-bearing austenitic stainless steel, which provides superior corrosion resistance compared to standard 304L and 316L grades. These tubes are highly suitable for applications exposed to acidic, chloride-rich, and corrosive environments, making them a preferred choice for chemical processing, pharmaceutical, and food industries.
The chemical composition of Stainless Steel 317L ensures its exceptional durability and resistance to pitting and crevice corrosion. The alloy typically contains 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum carbon content of 0.03%, along with minor amounts of manganese, silicon, phosphorus, and sulfur. This composition gives the tubes excellent mechanical strength, high temperature tolerance, and long service life.
Mechanically, SS 317L Needle Tubes exhibit impressive tensile strength, yield strength, and elongation properties. They typically have a tensile strength of 595 MPa, a yield strength of 260 MPa, and elongation of 55%. These properties make them suitable for precision applications where strength, flexibility, and reliability are crucial, such as medical devices, instrumentation, and industrial equipment.
