Vinit Stainless, which is established in Chennai, India, is a well-known producer and supplier of high-quality stainless steel products with a specialty in superior-grade tubing solutions. Of their comprehensive product list, SS 305 Tubing is prominent due to its superior formability and corrosion resistance. With the capability to fulfill the demands of industries that need non-magnetic stainless steel, SS 305 Tubing is produced under tight quality controls and in multiple sizes and specifications. Through a robust customer-focused strategy and conformity to international quality standards, Vinit Stainless has acquired a faithful customer base in industries such as automotive, food processing, and chemical.
SS 305 Tubing is an austenitic stainless steel alloy with a main content of 17–19% chromium and 10.5–13% nickel, but lower carbon content and higher nickel to minimize work-hardening. This composition adds formability and corrosion resistance. The tubing generally has a tensile strength of approximately 515 MPa, yield strength of 205 MPa, and elongation of 40%. It is free from magnetism in the annealed state and possesses superior ductility and toughness at cryogenic temperatures. Its characteristics render it especially ideal for deep drawing, spinning, and forming operations without sacrificing strength or durability.

SS 305 Tubing is extensively employed where higher formability and non-magnetic characteristics are necessary. It is well-suited for deep-drawn products like automotive trim, kitchenware utensils, appliance parts, and electrical components. The tubing can be used in mildly corrosive conditions and is thus suitable for food processing machinery, chemical equipment, and decorative architecture. In addition to this, SS 305 Tubing is also applied in the production of battery containers and other electrical devices having low magnetic permeability requirements. Its good surface finish and flexibility to welding and forming processes make it a generally applicable material across a number of industries, such as medical and consumer goods production.
