Spring material and what is the allowable stress?

Spring at work often suffer the effect of variable load and impact load, in order to ensure that in the spring can be worked on for a long time, the material must have high ductility and ultimate strength limit, the other should have enough ductility and plastic deformation, and its excellent adjustable qualitative reasoning.
Spring material and performance can view the relevant guidelines, standards and specifications (
GB /架T129。
6 -
92，GB4357-
89).
。
Spring manufacturer introduces common spring steel key are the following: 1, carbon spring steel such spring (
Such as 65, 70 steel, etc. )
Has the advantage of low price, convenient raw material comes from, defect is low ductility limits, when repeated deformation easy loss of ductility, and can no longer all work normally below 130 degrees Fahrenheit.
2, low manganese spring steel spring steel (such
If 65 mn)
Compared with carbon spring steel, the advantage is good cutting performance and higher compressive strength;
Defects are very easy to cause crack and hot ductility after heat treatment.
But because the price is low, so common in manufacturing specifications on general mechanical equipment is not spring, such as clutch spring, etc.
3, silicon manganese spring steel (this kind of steel
For example, 60 si2mn)
Due to add the silicon, so can significantly improve ductility limits, and improve the reliability of tempering, can therefore
at higher temperature tempering, and get excellent structural mechanics performance. Silicon-manganese spring steel obtained widespread use in industrial production, commonly used to manufacture cars, big tractor spiral spring, etc. 4, chrome vanadium steel such steel ( For example, 50 crva) Add the goal is to optimize vanadium institutions, improve the compressive strength and ductility of steel. The milk of this kind of material fatigue and impact resistance performance is good, can - again 40 degrees - — 210 degree temperatures of work, but the price is too expensive. Much to high places, such as to produce aircraft engine adjustment of spring in the software of the system. In addition, some of the material such as stainless steel and brass, having the features of corrosion resistance, brass also has brought the magnetic and electrical conductivity, so used to manufacture chemical machinery equipment, or in the job in etching in the spring of matter. Its defect is not easy conditioning treatment, structural mechanics performance is weak, so very little use in the general mechanical equipment. Spring factory advice when choosing materials, should give full consideration to the spring, critical level, the main purpose of applied standard ( Contains the load characteristics, size and characteristics of the circulation system, the delay time in the work, work temperature state and the surrounding material, etc. ) Conditioning treatment, the production processing, the elements and rationality, etc. In addition, but also refer to the spring of machinery and equipment in the application, choose to compare common material.
Competitiveness policy of Dongguan Yongqiang spring hardware Co.,Ltd. is about existing clusters as a platform for upgrading microeconomic fundamentals, where structural policies aim to change the industrial composition of an economy more directly.
