Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 305 Nuts, proudly located in Cape Town, South Africa. These nuts are specifically crafted for applications that require outstanding corrosion resistance, non-magnetic characteristics, and excellent formability. Njabulo Stainless provides a diverse range of 305 nuts, including hex nuts, lock nuts, and custom fasteners, catering to various industries such as food processing, chemical handling, automotive, and consumer goods. Each product is produced under stringent quality standards, ensuring they deliver durability and performance for both functional and decorative uses.
Stainless Steel 305 Nuts are constructed from an austenitic stainless steel alloy that contains around 17–19% chromium and 10.5–13% nickel, featuring a higher nickel content than 304 to minimize work hardening. This unique composition grants them exceptional cold-forming capabilities, making it easy to manufacture intricate shapes. These nuts boast a tensile strength of approximately 515 MPa and retain their corrosion resistance even in mildly corrosive and oxidizing environments. Their low magnetic permeability in the annealed state makes them ideal for applications where non-magnetic properties are crucial.
