What are the materials for a multifunctional screwdriver?

Screwdrivers are commonly used tools in our lives. In our home life, we must tinker with them. At this time, screwdrivers can come in handy. But there are many screwdrivers on the market. The editor will tell you what material is good for the multi-function screwdriver. 
 
Why look at the material? First of all, the hardness of the screwdriver is very high, and it also uses its hardness to work when it is used. Therefore, if the selected screwdriver is not suitable, it is easy to cause great damage to the screw under the condition of improper use, and the hardness is too high. Poor, it will also make the wear resistance of the screw worse, so a good screwdriver is a good screwdriver, and there will be no worries when using it, so we must use snacks when choosing. 
 
Generally speaking, the heads of high-quality screwdrivers are made of spring steel with relatively high hardness. The basic standard is to be hard but not brittle, and hard and tough. If the opening of the screw head becomes bald and slippery, you can hit the screwdriver with a hammer at this time to make the groove of the screw deeper, so that the screw can be easily unscrewed. At this time, make sure that the screwdriver is unscathed. In life, screwdrivers are often used to pry things, so at this time, the screwdriver is required to have a certain toughness and not bend or bend. In general, it is hoped that the hardness of the screwdriver head is greater than HRC60, and it is necessary to ensure that it is not easy to rust. If it is easy to rust, no matter how good the screwdriver is, it is no longer easy to use. 
 
1-Carbon Steel (CS)  
Carbon steel refers to a type of steel without other specific elements and the mass fraction of carbon is less than 2.11%. The advantages are high hardness and high strength, and the disadvantage is poor toughness. This steel is not suitable for screwdrivers, but is widely used for some general tool materials. 

2-chrome molybdenum steel (Cr-Mo)
This steel has good impact resistance, good hardness and toughness. It is generally used to make top screwdrivers and small hexagonal wrenches. It is an alloy of chromium, molybdenum, iron and carbon, but the material is relatively expensive. 

3-chrome vanadium steel (Cr-V)
This material has good strength and toughness, and is the ideal material of choice for making wrenches, screwdrivers, etc. It is an alloy of chromium and vanadium elements, and the price is not so expensive. It is a common material for screwdrivers in life. 
 
4-S2 tool steel
This alloy is a kind of excellent impact-resistant steel, used to make high-hardness Allen wrenches, screwdrivers, etc. Tools made of this steel have a sufficiently high hardness after heat treatment. Has good wear resistance, with certain strength and toughness. However, in the actual selection and application of screwdrivers, the use of chrome-vanadium steel is not as good. 

The above is all about the good material of the multi-function screwdriver. The common tool in life is the screwdriver. No matter what is broken, we must try to repair it first, so as to ensure our life is more comfortable and convenient. Jingmu (Zhongshan) Machinery Co., Ltd.
