Q4: What makes stainless steel stainless?
A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q5: Can stainless steel rust?
A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

- Q: What are the specifications for steel strips used in the production of watches?
- The specifications for steel strips used in the production of watches can vary depending on the specific requirements of the watch manufacturer. However, there are some general specifications that are commonly used in the industry. Firstly, the steel strips used in watch production are typically made from high-quality stainless steel. Stainless steel is chosen for its durability, corrosion resistance, and aesthetic appeal. The thickness of the steel strip can vary, but it is usually in the range of 0.10 to 0.30 millimeters. This thickness allows for the creation of thin and lightweight watch components while still maintaining structural integrity. The width of the steel strip is also an important specification and can vary depending on the design and size of the watch. Common widths for watch steel strips range from 4 to 20 millimeters. In terms of surface finish, watch steel strips are often polished to achieve a smooth and shiny appearance. The level of polish can vary, with some watches featuring a high mirror-like finish, while others may have a brushed or matte finish. Another important specification is the hardness of the steel strip. Watch components require a certain level of hardness to ensure they can withstand daily wear and tear. The hardness is usually measured on the Rockwell scale, with a typical range of 45 to 60 HRC (Rockwell C scale). Furthermore, the steel strips used in watch production may undergo additional treatments such as heat treatment, coating, or plating to enhance their performance, durability, or visual appeal. It is important to note that these specifications can vary depending on the specific watch brand and model, as different manufacturers may have their own unique requirements and preferences. Therefore, it is essential for watchmakers to ensure they source steel strips that meet their specific specifications and quality standards.
