Description	TOKKIN 305M is a highly stable austenitic stainless steel developed from SUS305. Based on the SUS304 (18Cr-8Ni) composition, this grade contains increased levels of nickel (Ni), manganese (Mn), and chromium (Cr), which stabilize the austenitic structure and significantly reduce the tendency for magnetization after cold rolling and forming operations. TOKKIN 305M is specially engineered with alloy contents adjusted toward the upper end of the JIS SUS305 specification range, resulting in greater austenite stability than conventional SUS305 materials. The higher nickel content also contributes to excellent formability, corrosion resistance, and processing performance, making it ideal for precision electronic and medical applications where magnetic influence must be minimized. Main Features: Outstanding Non-Magnetic Properties Maintains extremely low magnetic permeability and resists magnetization even after extensive cold working. Enhanced Austenite Stability Higher Ni, Mn, and Cr content improves phase stability compared with standard SUS305 and SUS304 grades. Excellent Formability Superior deep-drawing, bending, and stamping characteristics enable complex precision component manufacturing. Superior Corrosion Resistance High nickel content enhances resistance to corrosion in a wide range of environments. Suitable for Precision Electronics Ideal for electronic and communication devices where magnetic interference must be avoided. Medical Device Compatibility Frequently used in medical equipment and needle components requiring corrosion resistance and non-magnetic performance. TOKKIN 305M is commonly used in camera modules, communication equipment, medical devices, indwelling needles, motor components, and other precision applications where non-magnetic characteristics, excellent formability, and corrosion resistance are critical requirements.
