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: What is the difference between seamless and welded stainless steel pipes?
- The main difference between seamless and welded stainless steel pipes lies in their manufacturing process and the resulting characteristics of the pipes. Seamless stainless steel pipes are produced by piercing a solid billet or ingot, heating it to a high temperature, and then rolling it into a hollow cylindrical shape. This process ensures that there are no seams or joints in the pipe, resulting in a smooth and uniform surface. Seamless pipes are generally considered to have higher strength and better corrosion resistance compared to welded pipes. They are also preferred in applications where high pressure or temperature is involved, as their seamless nature makes them more reliable and less prone to leaks. On the other hand, welded stainless steel pipes are manufactured by joining two or more pieces of steel together using various welding techniques. This process introduces a seam or weld line along the length of the pipe. Welded pipes can be produced in a continuous or intermittent welding process, depending on the required specifications. While welded pipes may have slightly lower strength and corrosion resistance compared to seamless pipes, advancements in welding technology have significantly improved their quality and performance. Welded pipes are generally more cost-effective and commonly used in applications where lower pressure or temperature is involved. In summary, the difference between seamless and welded stainless steel pipes lies in their manufacturing process and resulting characteristics. Seamless pipes, with no seams or joints, offer higher strength, better corrosion resistance, and are preferred in high-pressure or temperature applications. Welded pipes, with welded seams, are more cost-effective, commonly used in lower-pressure or temperature applications, and have seen significant improvements in quality and performance. Ultimately, the choice between seamless and welded pipes depends on the specific requirements of the application and cost considerations.
