Extension Springs with Hook Ends&Corrosion-Resistant Extension Springs with Hook Ends

Extension Springs with Hook Ends&Corrosion-Resistant Extension Springs with Hook Ends
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch or mm of extension.
Zinc-plated springs have mild corrosion resistance.Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to extend than steel springs. As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch of extension or, for metric springs, millimeter of compression.
302 stainless steel springs have good corrosion resistance.
316 stainless steel springs have excellent corrosion resistance.    

A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external forces and return to their original state after removing external forces. Also called "spring". Generally made of spring steel. Spring types are complex and varied, according to the shape of the points, mainly spiral springs, scroll springs, plate springs, shaped springs, and so on. The mass-production material of the spring is piano steel wire or similar materials. The spring can be divided into stretching spring, compression spring, torsion spring, and bending spring, according to the shape can be divided into dish spring, ring spring, plate spring, spiral spring, truncated conical scroll spring, and torsion bar spring, etc, according to the production process can be divided into cold spring and hot spring. Ordinary cylindrical spring is the most widely used because it is simple to manufacture, and can be made into various types according to the load condition, and has a simple structure. Spring manufacturing materials generally should have a high elastic limit, fatigue limit, impact toughness, and good heat treatment properties, commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy, and rubber. The spring is manufactured by the cold winding method and hot winding method. The diameter of the spring wire is less than 8 mm, and the cold winding method is generally used for those greater than 8 mm. Some springs are also forced or shot peening after being made, which can improve the bearing capacity of the spring.
