Spring fatigue strength is what factors influence?
Spring manufacturer to tell you what are the factors influencing the spring fatigue strength, together and see it!
Yield strength of material has certain correlation between yield strength and the fatigue limit, in general, the higher the yield strength of the material, the higher fatigue strength is, therefore, in order to improve spring spring fatigue strength should find ways to improve the yield strength of material, or selects the yield strength and high compressive strength ratio of the material.
For the same material, fine crystal mechanism than the size of the crystals have higher yield strength.
with large surface conditions in-situ stress more on the surface of spring material, so the surface of the spring quality is quite big to the harm of fatigue strength. Spring material in cold rolling, drawing, and in the whole process of production leads to cracks, defects and scar defect is usually lead to spring fatigue rupture. The smaller the surface roughness, the smaller the stress, fatigue strength is also higher. The harm of material surface roughness on fatigue limit. With the ascension of surface roughness, the fatigue limit is reduced. In the same conditions, surface roughness of different steel grades and different methods of production
the fatigue limit to reduce level is different also, such as cold coil spring to reduce levels constant pressure specific heat coil spring. Due to the steel hot coil spring and tempering heat treatment, because the air oxidation make the spring material surface is not smooth and carburizing conditions, that would reduce the fatigue strength of the spring. On the material surface cutting, crush, shot blasting derusting and extrusion, etc. To be able to improve fatigue strength of the spring.
Building a brand as Yongqiang from the very start is simple so long as you keep 'the three C's' in mind: clarity, consistency and constancy.

News is one of the best products sold in the market today.
In terms of News, why is it different than other production? How does it fit a true need or desire for your requires? Is it simple to use? Make life easier?
It's not enough to have an idea as News in a gigantic market. The key to what gets concerned is how you connect this hungry market to the idea that satisfies it.
