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:What are the categories of springs?: A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and are restored to original shape after removal of external forces. Also made as a spring". Usually made of spring steel. The type of spring is complex and varied. According to the shape, there are mainly spiral spring, scroll spring, plate spring, special-shaped spring and so on.

Q:Is the car short spring good?: Because of the short spring, the fluctuation of the whole suspension system is too small, and the damping of the shock absorber system changes too directly, so that the comfort of the vehicle will decrease. That means it's going to be pretty bumpy.

Q:How about the size of the elasticity?: The force is analyzed and the force is decomposed along the positive plane and its vertical direction

Q:How to distinguish between spring steel and stainless steel: With saline in two days to put a steel can see rust is a way (can, for 304 stainless steel 201 stainless steel will rust, only less); another way is to put the two kinds of steel can see the reaction is on spring steel in dilute sulfuric acid, oxalic acid, not the reaction or reaction of small stainless steel.

Q:What is spring pressure and height?: Press the compression spring to the point where each circle is tight. Press it and press it high

Q:What are the main functions of spring?: Measure the magnitude of forces, such as springs, scales, and springs in a dynamometer

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:The shop glass spring door is too tight, how to adjust?: The spring of the stainless steel cover apart, there are 3 word brass wire, a label is in the middle of the elastic adjustment, Zuo Song left right tight, elastic, elastic, dextral (clockwise) that don't mix too much, a little bit, take it for a test drive, if you do not have the best mark pen in a gong wire above the mark, next to the two speed is adjustable,Note, the label ripped open, there will be no warranty, and all gongs silk must not be twisted out, only minor adjustments

Q:The glass door spring is broken. How much would it cost to change it?: Replace the ground spring, the price of the earth spring itself, but also part of the labor costs, after all, it is very expensive. Land springs in general, if used in general, that is, about 150, but with labor costs, usually around 80. Specific prices should be based on your actual situation, you and the master speak.
