An SS double torsion spring is a type of mechanical spring made from stainless steel that is designed to provide torque or rotational force in opposite directions. This type of spring is formed from a single piece of stainless steel wire that has been tightly coiled in opposite directions to form two helical springs that are connected by a central body.

Double torsion springs are commonly used in a variety of applications where rotational force or torque is needed, such as in automotive components, household appliances, and industrial machinery. They are also used in applications where space is limited and where a traditional single torsion spring may not be practical.

The use of stainless steel in the construction of double torsion springs provides several benefits, including excellent resistance to corrosion, durability, and high tensile strength. This makes them suitable for use in harsh environments where exposure to moisture, chemicals, and other corrosive substances is a concern.
