Q: Is spring steel manganese steel?: The most important characteristic of manganese steel is that it can be worked hard under strong impact and extrusion, and its wear resistance is improved, mainly by its working hardening.Spring steel mainly requires large elasticity, high yield strength, and can withstand repeated load without breaking. Spring steel only after heat treatment (quenching + medium temperature tempering) can show its high elasticity, that is, after a certain load, does not occur permanent deformation. The content of Mn in spring steel is much lower than that of Mn in manganese steel.

Q: Stainless steel and spring steel hardness, who is hard?: Hardness is checked by indentation, not by pliers.Stainless steel, of course

Q: What are the categories of springs?: A compression spring is spring under axial pressure, the material section in which are round, rectangular and is also useful multi strand steel rayon coiled spring, generally for pitch, compression spring shapes: cylindrical, conical, convex and concave and a small amount of non circular, will there is a certain gap between the ring and the ring compression spring, when subjected to external load when the spring contraction deformation, deformation energy storage.

Q: What's the spring material to?: There are many kinds of spring steel, the most commonly used are 65Mn and 60Si2Mn.

Q: How to choose spring steel material?: Spring steel is selected on the basis of the section size of the spring, such as high carbon steel 65, suitable for production in the spring of 12 ~ 15mm under section 60CrMnA, suitable for the production of spring and the car less than 50mm in diameter with heavy-duty spring. The 30W4Cr2VA is used to make heat-resistant spring for work below 500 degrees centigrade. Generally, hot forming springs are generally quenched and tempered at moderate temperature to obtain a structure with a maximum elastic limit and fatigue properties

Q: What is an independent bagged spring?: Independent spring: there are different springs, respectively, according to different weight, set up independent spring in different locations. Of the two men lying on it, one rolled over or left, and the other was not affected at all. Two mattresses in the middle area, the spring has different support strength, so won't feel sleep in the two bed crevice.

Q: How should we choose the spring material?: Large and medium-sized spring for load precision and stress higher, should choose cold drawn or cold drawn after polishing steel, for load precision and stress lower spring products, can choose hot rolled steel.

Q: How about the size of the elasticity?: Also called elastic force". The object by the force deformation, if the external force is removed, the object can return to its original shape of the elastic force, called "". Its direction is opposite to the external force that causes the object to deform. There are many different kinds of deformation, so there are different forms of elasticity. For example, when a heavy object is placed on a plastic sheet, the bent plastic should be restored to its original state and produce upward elasticity, which is its support for the heavy object. Hanging an object on a spring, the object stretched the spring, the elongated spring to restore the original state, resulting in upward elasticity, which is its pulling force on the object. Not only plastic, spring and so on can occur deformation, any object can deformation, no deformation of the object does not exist. However, some of the deformation is obvious, can be seen directly; some deformation is very small, must be aware of the instrument.

Q: What are the main functions of spring?: Control the movement of a machine, such as a spring that controls the opening and closing of a cylinder valve in an internal-combustion engine, and a control spring in the clutch

Q: How to distinguish between spring steel and stainless steel: Stainless acid resistant steel, or stainless steel, is made up of two parts: stainless steel and acid resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel resistant to chemical corrosion is called acid resistant steel. Spring steel is a quality carbon steel, but it can rust.
