Definition of stainless steel(Adopted form Wikipedia)
In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",
is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does,
but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,
or poor circulation environments. It is also called corrosion-resistant steel or CRES
when the alloy type and grade are not detailed, particularly in the aviation industry.
There are different grades and surface finishes of stainless steel to suit the environment
the alloy must endure. Stainless steel is used where both the properties of steel
and resistance to corrosion are required.

- Q: How do you remove scratches from stainless steel pipes?
- Here are some alternative methods to try when removing scratches from stainless steel pipes: 1. For cleaning the surface, start by using a mild dish soap and warm water. Gently scrub the scratched area with a sponge or soft cloth to eliminate any dirt or debris. 2. Create a thick paste by combining baking soda and water. Apply the paste to the scratched area, using a soft cloth to gently rub it in circular motions. Rinse off the paste with warm water and dry the surface with a clean towel. 3. Another option is to use non-gel toothpaste. Apply a small amount to the scratched area and use a soft cloth or sponge to rub it in gentle circular motions. Rinse off the toothpaste thoroughly with warm water and dry the surface completely. 4. Look for a specialized stainless steel cleaner designed specifically for these surfaces. Follow the instructions provided on the packaging, as different products may require varying application methods. Use a soft cloth or sponge to gently rub the scratched area with the cleaner. Rinse off the cleaner with warm water and dry the surface entirely. 5. In case the scratches are deep or extensive, it might be worth considering a stainless steel scratch remover kit. These kits typically include abrasive pads and a polishing compound to help buff out scratches. Follow the instructions provided with the kit for the best results. Always test any cleaning or scratch removal method on a small, inconspicuous area of the stainless steel pipe before applying it to the entire surface. Additionally, avoid using abrasive materials or harsh chemicals that could cause further damage to the stainless steel.

- Q: What are the standard sizes for stainless steel pipes?
- The standard sizes for stainless steel pipes can vary depending on the industry and application. However, there are some commonly used standard sizes that are widely available. In general, stainless steel pipes are produced in nominal sizes ranging from 1/8 inch to 72 inches in diameter. These sizes are typically classified using the Nominal Pipe Size (NPS) system, which refers to the approximate internal diameter of the pipe. The NPS sizes commonly used for stainless steel pipes range from NPS 1/8 to NPS 36. Additionally, stainless steel pipes are available in various schedules, which indicate the wall thickness of the pipe. The most commonly used schedules for stainless steel pipes are Schedule 5, Schedule 10, Schedule 40, and Schedule 80. It's important to note that these standard sizes may vary slightly depending on the country or region. Therefore, it is advisable to consult the relevant standards and regulations specific to your location or consult with a supplier to determine the exact standard sizes available for stainless steel pipes in your area.
- Q: How do you calculate the maximum allowable span for stainless steel pipes?
- In order to determine the maximum allowable span for stainless steel pipes, various factors must be taken into consideration, including the material properties, dimensions, and applied load of the pipe. To begin, one must ascertain the material properties of the stainless steel pipe, such as its yield strength, ultimate tensile strength, and modulus of elasticity. These values can typically be obtained from the manufacturer's specifications or engineering handbooks. Next, the dimensions of the pipe must be identified, specifically the outside diameter and wall thickness. These measurements are crucial for determining the pipe's moment of inertia, which directly impacts its ability to resist bending. Once these values are determined, the appropriate formula or calculation method can be applied based on the type of load the pipe will experience. Calculations differ depending on whether the load is uniformly distributed, concentrated at specific points, or a combination of both. For instance, if the load is evenly distributed along the span, the formula for maximum deflection or sag can be utilized. This formula takes into account the pipe's modulus of elasticity, moment of inertia, applied load, and span length. However, if the load is concentrated at specific points, consideration must be given to the maximum bending stress. This calculation involves determining the bending moment, which is influenced by the load, span length, and the pipe's moment of inertia. By comparing this bending stress to the pipe's yield strength, it can be ensured that the stress does not exceed the allowable limit. It is important to note that different codes and standards may provide specific guidelines for calculating the maximum allowable span for stainless steel pipes. Therefore, it is advisable to consult relevant industry standards or seek the guidance of a qualified engineer to ensure accurate calculations and compliance with safety regulations.
