Helical spring, we can also call it spiral spring.It is the composition of wounded flat ribbon metal with round cross section, typically in stainless steel and other alloy material.The load evenly spreads across each individual band. Therefore it has a relatively high spring load with smaller deflection range.
Helical spring usually be made of 301 Stainless Steel, Hastelloy C276, Elgiloy or equivalent, 316 Stainless Steel, Beryllium Copper (BeCu) and other materials what you want.And the length, sizes of helical spring can also be customized.According to the shape and winding direction, helical springs can be divided into ordinary cylindrical helical springs, variable diameter helical springs, and left and right springs.
Helical springs are commonly used for medium to high pressure applications under very slow or static condition.Recommended for vacuum and cryogenic sealing application.They are specifically used in Petrochemical Industry,Oil & Gas Industry,Semi-Conductor Industry,Food and Beverage Industry,Mining Industry and many other industries.To sum up, Helical Spring has been widely used in various fields with its unique structural characteristics and excellent performance advantages.
