Steel Belt (19)

The above figure shows the relation between the load and the expansion when the metal is put on the testing machine, which metal is pulled by the machine.
The steel belt uses all the spring steels. Because the weld of the steel belt receives the heat influence when welding, strength is also weak. Therefore, it breaks by a numerical value that is lower than the parent metal.
For your information, the upper yield stress doesn't appear to the stainless steel like mild steel.
