Quantity
M3 Stainless Steel 304 Nut—made of SUS304 austenitic stainless steel, conforms to DIN934, supplied with a bright natural finish for corrosion resistance; height 2.15–2.4 mm, ideal for precision 3C, medical, and instrumentation applications. It withstands over one hundred install/remove cycles without thread stripping, passes salt-spray test ≥480 h, meets export-grade quality, and ships from stock.
SS304 (stainless steel 304) is the preferred material for M3 Stainless Steel 304 Nut as well as for food equipment and medical devices, thanks to its core advantages summarized as “three highs and three resistances”:
1. High corrosion resistance
With 18 % Cr and 8 % Ni, it forms a dense passive film that withstands atmosphere, fresh water, weak acids and alkalis, and many organic media; salt-spray ≥480 h without rust ensures M3 Stainless Steel 304 Nut remains free of rust spots over the long term.

2. High toughness
The face-centered-cubic austenitic structure offers moderate cold-work hardening, keeping the threads of M3 Stainless Steel 304 Nut sharp while resisting brittle fracture, allowing repeated assembly and disassembly.

3. High hygiene safety
Compliant with GB 4806.9-2016 and FDA 21 CFR 177.2600, with no heavy-metal leaching, M3 Stainless Steel 304 Nut can safely contact food, pharmaceuticals, and the human body.

4. High-temperature resistance
Continuous service temperature up to 800 °C; retains strength at 900 °C for short periods, suitable for high-temperature sterilization or engine surroundings, thereby broadening M3 Stainless Steel 304 Nut’s application range.

5. Low-temperature resistance
Maintains excellent impact toughness down to –196 °C, ideal for LNG and liquid-nitrogen lines, and equally applicable to M3 Stainless Steel 304 Nut in ultra-low-temperature service.

6. Magnetic-interference resistance
In the annealed condition its magnetism is extremely low, avoiding interference with precision electronics and medical imaging equipment, giving M3 Stainless Steel 304 Nut an extra edge in sensitive environments.
