Know the composition and characteristics of spring steel:
Spring steel Spring steel, a low alloy, medium carbon steel or high carbon steel with a very high yield strength This disambiguation page lists articles associated with the title Spring steel. It consists of an alloy of iron and carbon, and may have some other metals such as manganese, silicon, and chromium put into it to have more desirable characteristics. Spring steel is grouped into low-alloy steel and high-alloy steel, which is mainly used to manufacture springs and circular springs spring bending and deformation resistance performance.
Different uses of spring stock in industries:
Due to the unique property, spring steel is applied in many areas. It is widely used in automotive, industrial, and general use for producing suspension springs, clutch springs, and seat springs. The manufacturing of curtain rods and window springs fall under the construction sector that utilizes spring steel. It is also employed in the production of tools, household appliances and musical instruments.
Mechanical properties of spring-steel and tuning of performance:
The mechanical characteristics of spring steel are important because of the practical value. Spring steel is characterized by its high yield strength and resistance to fatigue. These characteristics of spring steel enable it to maintain large amounts of energy while undergoing significant loading and unloading (even though it has undergone repeated cycles of such loading). In addition, spring steel have good wear resistance and fatigue resistance, can withstand the hard use in various harsh environments.
Comparison of various steels for use as springs:
There are many grades of spring steel which are used in varying applications. Some of the general categories of spring steel wire are EN 47, EN 42, EN 45. EN 47 has a high tensile strength and high fatigue resistance so should be classed as a heavy duty spring wire. EN 42 is medium carbon steel having moderate tensile strength. It is used to make spring and high-strength wire. EN 45 is used on hammers, chisels, implement knives etc. which ensures good shock resistance and wear resistance.
Heat treatment of spring steel to maximize struck durability:
Heat treatment is the key process of spring steel production. Heat treatment is that the steel is heated to a particular temperature, and this temperature may be maintained for several hours, and then the steel is required to be cooled quickly. This enhances the hardness, strength and ductility of the spring steel, making it more durable and sturdier than general. Typical heat treatment for spring steel involves normalizing, quenching, and tempering.
