Frequently asked question (FAQ)

Question: What is the initial tension?: Answer: It can be understood that when a general tensile spring is under tension, the tension measured when it is about to undergo elastic deformation without deformation (critical state) is called the initial tension. It is realized by properly controlling the process parameters in the manufacturing process of tensile spring.
MISUMI tension spring specifications (except for free designation) have been standardized, i.e. the maximum load of the same diameter is a certain value. Because the tensile spring is made on the basis of the maximum load, the initial tension and spring coefficient are the reference values.
Question: What is the life of the tensile spring?: Answer: Some hook installation methods of tension springs may cause stress concentration, so the standard use times cannot be provided. To increase the use times, it is recommended to use it under 70% of the allowable displacement Fmax.
· It is recommended to use it at room temperature below 40°C, and the load value will decrease due to service conditions at temperatures over 40°C .
Question: What is the spring constant?: Answer: The spring constant is the force necessary to give the spring unit displacement, which is used to express the characteristics of the spring.
Question: What are the JIS standards for general spring-related materials?: Answer: Piano wires: JIS G 3522
Iron wires: JIS G 3532
Hard drawn steel wires: JIS G 3521
Stainless steel wires for springs: JIS G 4313
Question: What is the difference between a piano steel wire spring and a hard drawn steel wire spring?: Answer: There is little difference in appearance between the two materials. In short, the piano wire is an advanced material, and the hard drawn steel wire is a general material.
The piano wire is often used as a spring for precision machinery while the hard drawn steel wire is mostly used as a peripheral spring for groceries or blinds.
They are both high-carbon steels with almost the same chemical composition. The production of piano wires is time-consuming and they are expensive because there is additional standardized management and inspection of impurities, the depth of surface scars, and the depth of decarburized layer.
Although the subtle difference is invisible to the naked eye, it has a great influence on the quality of the spring.
