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: How are steel rails designed to handle thermal expansion?
- Steel rails are equipped with a combination of factors to handle thermal expansion. Firstly, the material chosen for steel rails is carefully selected to have a low coefficient of thermal expansion. This selection ensures that the steel is less likely to expand or contract with temperature changes. By opting for a material with a low coefficient of thermal expansion, the rail becomes more resilient to the stresses caused by thermal fluctuations. In addition to material selection, rail design also plays a vital role in managing thermal expansion. Typically, small gaps known as expansion joints are incorporated between the rails. These gaps allow the rail to freely expand and contract without causing excessive stress or buckling. The length of these expansion joints is precisely calculated to provide sufficient space for expansion while also maintaining the rail system's integrity and stability. Furthermore, the rail fastening system is designed to accommodate thermal expansion. The fasteners that secure the rail in place are often designed to allow slight movement, enabling the rail to expand and contract without causing any damage. This flexibility in the fastening system helps minimize the stresses or strains on the rail caused by thermal expansion. Overall, the design of steel rails takes into consideration the potential for thermal expansion. It incorporates features such as material selection, expansion joints, and flexible fastening systems to ensure that the rail can handle temperature-induced changes without compromising its structural integrity.
