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 affected by train derailments?
- Steel rails can be significantly affected by train derailments. When a train derails, the force and impact of the accident can cause a range of damages to the steel rails. The most common damage is the bending or warping of the rails, which can result in misalignment or even complete detachment from the track. This can lead to disruptions in the train service and pose serious safety risks. In addition to bending or warping, train derailments can also cause the steel rails to crack or break. The excessive forces exerted during a derailment can exceed the rail's structural capacity, leading to fractures or complete failures. These breaks in the rails can further contribute to the derailment and subsequent damage to the train and infrastructure. Furthermore, the intense friction and dragging of train wheels against the rails during a derailment can cause severe wear and tear on the steel rails. This can result in the formation of grooves or indentations, which may compromise the smoothness and stability of the track. These deformations can affect the train's ability to maintain proper alignment and increase the risk of future derailments. It is worth noting that the extent of damage to steel rails during a derailment can vary depending on numerous factors, including the speed and weight of the train, the angle and force of impact, and the condition of the rails themselves. Following a derailment, thorough inspections and repairs are necessary to identify and rectify any damages to the steel rails to ensure the safety and efficiency of train operations.
- Q: What are the different types of rail joints used in steel rails?
- There are three main types of rail joints used in steel rails: the fishplate joint, the insulated joint, and the welded joint. The fishplate joint is the most common, where two rail ends are connected with a pair of metal plates and bolts. The insulated joint is used to create an electrical break in the rail, typically to isolate sections of track for signaling or power distribution purposes. Lastly, the welded joint is formed by welding the rail ends together, creating a seamless and continuous track.
- Q: How are steel rails protected against impact and shock loads?
- Steel rails are designed to withstand the impact and shock loads that they are subjected to in order to ensure the safety and efficiency of railway operations. There are several measures in place to protect steel rails against these forces. Firstly, steel rails are manufactured using high-quality steel materials that have excellent strength and durability properties. This ensures that the rails have the necessary resistance to withstand impact and shock loads. The steel used in rails is specifically chosen to have a high tensile strength, which allows it to absorb and distribute the forces generated by impact and shock loads. Secondly, steel rails are designed with specific shapes and profiles that enhance their ability to withstand these forces. The shape of the rail, such as the head, web, and base, is carefully designed to distribute the forces evenly and reduce stress concentrations. This helps to minimize the risk of deformation or failure when subjected to impact and shock loads. Additionally, steel rails are installed on a well-designed and maintained track system. The track components, such as the sleepers and ballast, play an important role in absorbing and dissipating the impact and shock loads. The sleepers, which support the rails, are typically made of concrete or timber and are designed to distribute the forces effectively. The ballast, which is the layer of crushed stones beneath the sleepers, provides stability and acts as a cushioning medium to absorb the forces. Furthermore, various fastening systems are used to secure the rails to the sleepers. These systems, such as rail clips and bolts, are designed to maintain the integrity of the rail alignment and prevent excessive movement or displacement during impact and shock loads. Regular inspection and maintenance of the rail infrastructure is also crucial to ensure its continued protection against impact and shock loads. Inspections, such as ultrasonic testing and visual inspections, are conducted to identify any defects or damages that may compromise the integrity of the rails. Any necessary repairs or replacements are then carried out promptly to maintain the safety and reliability of the rail system. In conclusion, steel rails are protected against impact and shock loads through the use of high-quality steel, well-designed rail profiles, a robust track system, secure fastening systems, and regular maintenance. These measures collectively ensure the durability and safety of steel rails, allowing them to effectively withstand the forces generated by impact and shock loads.
