This grade is based on SUS304 (18Cr-8Ni), a typical austenitic stainless steel, and has stabilized austenite phase by increasing chemical composition such as Ni, Mn and Cr, making it less susceptible to magnetization even after cold rolling.

TOKKIN 305M is adjusted these content at the higher level within the range of JIS SUS305, it exhibits increased stability compared to the typical SUS305.

Additionally, with a higher nickel (Ni) content, it has excellent processability and corrosion resistance.

TOKKIN 305M - UNS S30500 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 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, medical devices, indwelling needles, motor components, and other precision applications where non-magnetic characteristics, excellent formability, and corrosion resistance are critical requirements.

Precision Non-Magnetic Performance

TOKKIN 305M stands out for its superior non-magnetic properties, rendering it particularly ideal for sensitive electronic and medical applications where magnetic interference must be strictly minimized. Its composition ensures consistent performance in precision-engineered products.

Versatile Form Factors and Surface Finishes

Manufactured as both coils and sheets, TOKKIN 305M is available in bright and dull finishes. This adaptability allows it to be tailored to fit the specific requirements of varied industries, enhancing both functionality and visual appeal.

Stringent Japanese Manufacturing Standards

Sourced from premier manufacturers in Japan, this grade meets rigorous international standards, ensuring robust mechanical properties and reliable chemical composition for demanding export and supply chains.
