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: Want to practice how to use pectoral muscle spring expander: If your strength is not enough, a chest start even more difficult, not easy to do it.It is recommended that you should not rely solely on the chest muscle training, according to their ability, to start from the first push ups. Practice to a certain extent to practice chest.If possible, the best way is to do chest push arms parallel flexion, but more difficult.The best chest group 20, a group is appropriate.

Q: What is spring pressure and height?: That is, the spring is compressed to the height of the full circle.

Q: What kind of production equipment does spring factory usually have?: Multi function forming machine, coil spring machine, 580 press spring machine, extension spring machine, etc.Small heat treatment is also needed

Q: What's the spring material to?: 1, with alloy spring steel, respectively, there are several kinds of steel: 55Si2Mn or 50CrVA and 30W4Cr2VA, these alloy spring steel;2, manufacturing process:Coil the machine first into the spring and then proceed with the proper heat treatment process to get the spring you need.

Q: What kind of material does spring have?: Carbon spring steel: the material: 65#, 70#, 65Mn, 82B, 72A, 72B steel, is characterized by low plasticity, strong elasticity, anti stress ability. Application: mainly used for Simmons bed, car cushion, and all kinds of machinery, electric tools, stationery, sports equipment, torsion spring, spring, electrical equipment and other industries. Specifications: line diameter 0.20mm- GB4357-89 6.50mm. standard: carbon spring steel wire, national standard, main use: used to make cold formed in the cold state without hardening spring

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: I buy a spring made of 1.2mm steel wire from a hardware store that needs quenching: Spring: Spring quenching hardening is the steel is heated to the critical temperature of Ac, or Ac: the above heat preservation time, the austenite with greater than the critical cooling rate of rapid cooling, so as to obtain the heat treatment method of martensite.

Q: How to process Spring Steel: After the spring is made, shot peening can produce residual compressive stress on the surface of the spring so as to offset part of the working stress on the surface layer and restrain the formation of surface cracks, which can significantly improve the fatigue limit of the spring.

Q: Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert: According to the conservation of mechanical energy, the object should be a free fall motion at the upper end of the spring
