In the field of precision electronics, stainless steel materials are widely used, such as mobile phone parts, precision machinery, electronics and clocks, etc. 

These fields have very high performance requirements on materials. 

Stainless steel has various properties and can be adjusted according to various conditions. a requirement. 

Fluorescent display tubes used in video recorders and car console panels to display time and speed are made by bonding a glass backplane to a metal electrode. 

Therefore, a metal with a thermal expansion coefficient similar to that of glass must be used, otherwise cracks will appear on the contact surface of glass and metal. NAS 42-6/UNS K94760 Stainless Steel Material

The thermal expansion coefficient from room temperature to high temperature is similar to that of glass, and it is because of this characteristic that it is used as a lead wire for fluorescent display tubes.
