Rolex fans should have heard of 904L steel, but this material may only stay in the “cognitive” more durable, but they are not clear about the main difference with this kind of stainless steel 316L steel of other brand watches. While we do know the point is that the use of this steel will make a high cost so far, only Rolex brand watches adapt it fully. Thus, there are many people expressed doubts: ” in the end why 904L steel is expensive?” Today we will take luxury Rolex Explorer II 216570 replica watches as example to explore the main reason.
The first reason is that 904L steel cases copy watches are like metal in glossiness. 904L steel is mainly used in equipment such as chemical reactors, seawater processors and other high corrosive substances, so corrosion resistance is stronger than 316L. The causes of such differences come from the composition of alloy elements.
In addition, the 316L steel and 904L steel are almost the same, the main components are nickel, chromium and molybdenum, just in different proportion, and 904L also has a small amount of copper, so the corrosion resistance and wearing resistance is stronger than 316L, and there is no much difference on both the strength and hardness. Only rich Rolex can make use of this material. Of course, the price of Rolex fake watches with white dials are quite expensive.
