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 is the difference between a centerless ground and a hot rolled steel round bar?
- Two distinct types of steel bars are the centerless ground steel round bar and the hot rolled steel round bar. To begin with, the manufacturing process for each type varies. The centerless ground steel round bar is produced by passing it through a centerless grinder, which eliminates any surface imperfections and ensures a precise and smooth finish. This process guarantees tight tolerances and a consistent diameter throughout the bar's length. On the other hand, the hot rolled steel round bar is created by subjecting the steel billet to extremely high temperatures and then rolling it through a series of mills to achieve the desired shape and size. As a result, the surface finish of hot rolled steel bars is rougher compared to centerless ground steel bars. In terms of physical properties, centerless ground steel bars generally exhibit a higher level of dimensional accuracy and straightness due to the precision grinding process. This makes them suitable for applications requiring tight tolerances and precise measurements, such as the manufacturing of machinery parts or precision tools.
