FAQ:
Q1: How soon can we receive the product after purchase?
A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q2: What makes stainless steel stainless?
A2: 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.
Q3: Can stainless steel rust?
A3: 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 different types of steel round bar surface finishes for improved lubricity?
- There are several different types of steel round bar surface finishes that can be used to improve lubricity. 1. Smooth Finish: This is the most basic type of finish, where the surface of the round bar is made smooth through processes like grinding or polishing. A smooth finish helps to reduce friction and provides a good base for applying lubricants. 2. Chrome Plating: Chrome plating involves electroplating a layer of chromium onto the surface of the round bar. This creates a hard, smooth, and corrosion-resistant surface that provides excellent lubricity. Chrome plating is commonly used in applications where low friction and wear resistance are required. 3. Nitriding: Nitriding is a surface hardening process that involves diffusing nitrogen into the surface of the round bar. This creates a hard layer that enhances the lubricity of the steel. Nitriding is often used in applications where high wear resistance and improved lubrication are important. 4. Black Oxide: Black oxide is a chemical conversion coating that forms a black surface on the steel round bar. This finish provides a thin layer of protection against corrosion and also improves lubricity. Black oxide is commonly used in applications where lubricity is essential but a decorative appearance is not required. 5. Teflon Coating: Teflon coating, also known as PTFE (polytetrafluoroethylene) coating, involves applying a thin layer of Teflon onto the surface of the round bar. This coating provides excellent lubricity and low friction properties. Teflon coating is often used in applications where non-stick properties are required, such as in food processing or packaging industries. These are just a few examples of the different types of steel round bar surface finishes that can be used to improve lubricity. The choice of finish depends on the specific application requirements and the desired level of lubrication and wear resistance.
