How to select materials when using stainless steel for the SW6 saddle

It can be verified using PV Desktop.

When performing calculations using the SW6 saddle, if it is necessary to change the material type, this can usually be done directly in the software’s material input interface. However, if a stainless steel option is not available in the original software material library, you may need to manually enter the relevant parameters of the material, such as elastic modulus, Poisson’s ratio, density, etc. When selecting stainless steel materials, the following factors need to be considered primarily: corrosion resistance, heat resistance, strength, and dimensional stability. The specific type of stainless steel to choose depends on the actual application environment and design requirements. For example, if the saddle is to be used in high-temperature environments, a stainless steel material with good heat resistance should be chosen ； If the saddle is required to bear large loads, a stainless steel material with high strength should be selected. Overall, choosing stainless steel material is a process that involves considering multiple factors. If you are not well-informed about this, it is recommended to consult professionals or consult relevant materials. .

You can simply select a material with an allowable stress lower than that of stainless steel in SW6 for calculation; for example, Q235B. Of course, the allowable stress value for SS in GB/T150 cannot be used

Q235B is also much higher than S30408

The material safety factors for NB/T47065 and GB/T150 are different
