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.
Surface Finish :

- Q:What is the difference between nominal size and actual size in stainless steel pipes?
- The distinction between nominal size and actual size in stainless steel pipes lies in their measurement and labeling methods. Nominal size refers to the assigned name of a pipe based on its approximate dimensions, typically in inches or millimeters. This name serves the purpose of easy identification and standardization. In contrast, actual size refers to the precise measurements of the pipe, including its outer diameter (OD) and wall thickness. These measurements are usually expressed in fractions of an inch or millimeters. The accurate dimensions are vital for determining the pipe's compatibility with fittings, valves, and other components, as well as for calculating flow rates and pressure ratings. It is important to acknowledge that the nominal size of a stainless steel pipe may not always align with its actual size. This discrepancy arises from historical factors and manufacturing practices. In certain instances, the nominal size may be slightly larger or smaller than the actual size to account for variations in wall thickness or to conform to industry standards. Therefore, when selecting stainless steel pipes, it is crucial to consider both the nominal size and the actual size to ensure proper fit and functionality. Referring to the manufacturer's specifications or seeking professional advice can aid in determining the appropriate pipe size for a specific application.
- Q:What are the common sizes of stainless steel pipes used in construction?
- The common sizes of stainless steel pipes used in construction vary depending on the specific application and requirements. However, there are a few standard sizes that are commonly used in various construction projects. These include 1/2 inch, 3/4 inch, 1 inch, 1.5 inches, 2 inches, 3 inches, 4 inches, 6 inches, and 8 inches. These sizes are commonly used for different purposes. Smaller sizes like 1/2 inch, 3/4 inch, and 1 inch are often used for plumbing and water supply systems in residential and commercial buildings. They are also used for gas lines and ventilation systems. Larger sizes like 1.5 inches, 2 inches, 3 inches, and 4 inches are typically used for industrial applications such as oil and gas pipelines, chemical processing plants, and power generation facilities. These pipes are designed to handle higher flow rates and pressure requirements. Even larger sizes like 6 inches and 8 inches are used in more specialized applications such as large-scale industrial projects and infrastructure development. These sizes are often used for water treatment plants, wastewater treatment facilities, and large-scale irrigation systems. It is important to note that these are just some of the common sizes, and there are many other sizes available depending on the specific needs of a construction project. Consulting with a professional engineer or contractor is always recommended to determine the appropriate size of stainless steel pipes for a specific construction project.
