Rolex fans should have to know 904L steel, but the perception of this material may only stay in the “more durable” only, and do not know this stainless steel and other watches and clocks with 316L steel brand where different; but can Clearly, the use of this steel will make the cost higher than the length of the watch brand so far only Rolex full use of its watch. So, there are a lot of people expressed doubts: 904L steel in the end what is it?
The table is a common material containing K gold, titanium and ceramics, etc., which in turn accounted for the vast majority of stainless steel; and many watch brands have a Commonly used, it is the use of 316L steel, because of its low hypersensitivity characteristics, not only can be used to manufacture case, many need to wear jewelry, scalpels, etc. can be used 316L steel production, the objective point of view is quite good Material. However, Rolex in addition to the early use of this 316L steel, then the full use of 904L steel, what is the reason?
First of all, let us understand the difference between the two kinds of steel: 316L steel in addition to the aforementioned mentioned is not easy to cause allergies, is not easy to corrosion and deformation, so more for food processing and medical equipment; 904L steel is mainly used in chemical reactions Devices, seawater processors and other high-corrosive substances exposed to the equipment, so the corrosion resistance is stronger than the 316L. The reason for this difference in the composition of the alloy elements, 316L steel and 904L steel is almost the same, the main ingredients are nickel, chromium, molybdenum, but the proportion of different, 904L also a small amount of copper, so corrosion resistance And wear resistance is stronger than 316L, and both in strength and hardness is not much difference. In daily life, the case most likely to encounter problems no less than wear bumps and corrosion, although 904L and 316L steel wear resistance is sufficient, but the two are still corrupt in the difference. Although the watch is often exposed to corrosive substances are mainly sweat and humid environment, but the table itself, if often engaged in sea activities or diving, the higher requirements of anti-corrosion, that 904L steel is a better choice; and because 904L Steel has a higher metal purity, can be highly polished, so polished after processing can be more bright, beautiful effect. Only the cost of using 904L steel is relatively high, because 904L forging difficult, the production cost is also greatly improved. If only for corrosion and more beautiful, and have to replace the whole production line of the machine, this practice is really heroic, such as Rolex was done, so 904L also “labor” nickname.
