Q: Is spring steel manganese steel?: With wings are not necessarily the "angel", also may be "bird". Steel not containing Mn elements is called manganese steel. Manganese steel refers to those with high strength steel, mainly used for impact, friction and extrusion, mainly wear and tear.

Q: Buffer spring buffer for automobile: With abrasion resistance, cold resistance, impact resistance, aging resistance, water resistance, service life of 2 - 3 years. First, use Jack to support the body and clean the spring with water. After the installation is complete, the automobile damping buffer rotating around a few times, check whether the spring into full spring slot; the outer edge is rub the fender buffer; buffer overlap or not. Also, in order to avoid the shock absorber, when the vehicle is moving down to the bottom of the spring, it is necessary to install a stop card.

Q: What is spring pressure and height?: Press the compression spring to the point where each circle is tightPress height = = (total coil number -0.5) * steel wire diameter

Q: I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching: First of all, you don't know whether the material is suitable for springs.Gas torch burning red spring, water or oil? The quenching temperature is not too good. It's too difficult to control: it can't be just right. Besides, tempering is necessary after quenching. Without tempering, of course, very brittle (hardened case), to the temperature above 400 degrees insulation for a period of time.If you're patient, experiment slowly, I hope. But if you're discouraged, it's hard to succeed.

Q: How to choose spring steel material?: In determining the cross-section shape and size of spring materials, priority should be given to rejection of the national standards or ministerial standards for size specifications, as far as possible to avoid the use of non-standard specifications of materials. Although the spiral spring square or rectangular cross section material, the elastic deformation can be higher than, can make the small volume of the spring, for spring, in small space or under impact load but because of square or rectangular section material shortage, the price is higher, and the spring forming is difficult, so should be avoided. Ring section spring material diameter series see table 3-9.

Q: What kind of spring has the best performance?: Spring outside diameter, the same spring at both ends of the outer diameter and the middle of the outer diameter is not the same, unlike the spring, the force has a slight impact. The same batch is very different from each other, indicating that the machining accuracy is very poor.

Q: The shop glass spring door is too tight, how to adjust?: If it is the glass door of the ground spring, then call the installation worker to loosen it.

Q: Is the car short spring good?: Hello: no modification is recommended! Although the spring shortening can reduce the height of the body to make the car appear more sporty, it can also reduce partial roll during cornering. But it does more harm than good. Below say, change the disadvantage of short reed. First of all, lowering the body will affect the passing, and the over speed belt is easy to drag the chassis. Another major drawback is that the full set of shock absorbers consists of a helical spring and a hydraulic cylinder shock absorber.

Q: How to process Spring Steel: Spring steel has excellent comprehensive performance, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization, precise shape and size).

Q: The glass door spring is broken. How much would it cost to change it?: The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.
