Production Process
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 calculate the bending radius of stainless steel pipes?
- Several factors need to be considered when calculating the bending radius of stainless steel pipes. These factors include the diameter of the pipe, the wall thickness, and the specific type of stainless steel being utilized. To begin, one must determine the outside diameter (OD) of the pipe. This can be achieved by directly measuring it or by referring to the pipe specifications. Following this, the wall thickness of the pipe should be identified. This information can be found in the pipe specifications or measured using a caliper. Once the OD and wall thickness are known, it is possible to calculate the inside diameter (ID) of the pipe. This can be done by subtracting twice the wall thickness from the OD. This calculation accounts for the even distribution of the wall thickness on both sides of the pipe. Having obtained the ID, the bending radius can now be calculated. Usually, the bending radius is expressed as a multiple of the pipe's OD. A general rule of thumb for stainless steel pipes is that the bending radius should be at least three times the OD. However, this value may vary depending on the specific application and the type of stainless steel being used. It is important to note that bending stainless steel pipes beyond their recommended bending radius can result in deformation, cracking, or failure. Therefore, it is crucial to adhere to the manufacturer's guidelines and seek advice from an engineer or an experienced professional in working with stainless steel pipes to ensure accurate calculations.
