Q:What's the manganese content of spring steel?
Carbon spring steelThe carbon content (mass fraction) of carbon spring steel is usually 0.62%~0.90%. In accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.
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 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 kind of spring has the best performance?
The length of the spring, with a number of differences between the spring, will affect the product intensity consistency.
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 kind of production equipment does spring factory usually have?
Spring testing machines; fatigue testing machines; torsion testing machines; spring tension and compression testing machines
Q:What is flat steel? Plain carbon flat steel? Spring flat steel
Flat refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Plain carbon flat steel refers to carbon content of 0.06-0.22% flat steel. The spring flat steel refers to the flat steel with good elastic deformation ability.Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:The glass door spring is generally guaranteed for several years
but once you change the maintenance fees are higher than the artificial spring spring price itself
Q:What are the main functions of spring?
Absorb vibration and impact energy, such as damping springs in various kinds of vehicles and springs of various buffers
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.
