The most suitable stainless steels for shaver head are 304 and 440C, the reasonsas follows:
304 contains 18% chromium and 8% nickel, has good corrosion resistance, is easy to process into precision mesh, has low cost; it also has good plasticity, is easy to be made into precise mesh by stamping and etching, and the surface can be electroplated and polished to improve smoothness, and has moderate cost, and is widely used in mid-range products.
440C has a carbon content of 1.2%, a hardness of HRC58-60, a wear resistance far exceeding 304, and strong resistance to blade scratches; chromium content is 17%-18%, and corrosion resistance is close to 304, suitable for high-end models.
Pursuing cost-effectiveness and versatility: Choose 304 stainless steel, which is suitable for rotary shavers and daily household use, taking into account corrosion resistance and comfort.
Pursuing extreme durability and performance: Choose 440C stainless steel, which is especially suitable for reciprocating shavers and high-frequency use scenarios, and has lower long-term use costs.
Core logic: 304 wins with "comprehensive balance", and 440C is known for "hardness + wear resistance". Both are mainstream in the industry. You can choose according to product positioning and usage needs.
It is more convenient to use stainless steel coils or strips to make shaving net:
1.Morphological adaptation processing: Coils/strips are thin continuous structures that can be directly put on the machine for precision processing such as stamping and etching without additional cutting and slitting, reducing waste and processes.
2.Stable quality: This material has consistent thickness and smooth surface, and the mesh size is more accurate (such as the hole of the thickness of a hair), and it can be processed continuously in rolls, and the machine works non-stop, which is highly efficient.
3.Cheap and easy to store: The factory mass-produces this roll/strip material at low cost; it takes up little space when rolled up, and it is not easy to be crushed during transportation, and it can be unfolded at any time when used.
