FAQ:
Q1: What makes stainless steel stainless?
A1: 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.
Q2: Can stainless steel rust?
A2: 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.

These inspections are typically performed by trained professionals who visually examine the rails and use specialized equipment to measure their geometry and detect any defects. If any issues are identified during these inspections, appropriate maintenance measures are taken promptly. This may involve grinding the rails to remove surface irregularities and restore the desired profile. Grinding helps to reduce friction between the train wheels and the rails, improving ride quality, reducing noise, and minimizing wear on both the wheels and the rails. In addition to grinding, other maintenance activities include adjusting the alignment and gauge of the rails. This ensures that the track remains within the specified tolerances, preventing excessive wear, and reducing the risk of derailments. The curvature of the rails is also carefully monitored to ensure it remains within the designed limits. To maintain the integrity of the rails, they may also undergo periodic ultrasonic testing. This non-destructive testing method uses high-frequency sound waves to detect internal flaws, such as cracks or fractures, that may not be visible on the surface. If any defects are found, appropriate measures are taken to repair or replace the affected sections of the rail. Regular lubrication is another essential maintenance practice for curved railway tracks. Lubricants, such as grease or oil, are applied to the rail surfaces to minimize friction and wear. This helps to prolong the lifespan of the rails and reduce maintenance needs. Furthermore, vegetation control is crucial to prevent vegetation from obstructing the tracks and causing damage to the rails. Regular trimming and removal of vegetation is carried out to ensure clear visibility and prevent any interference with the structural integrity of the rails.
