Tips: Screwdriver materials
Generally, screwdriver steel material comes in four varieties (except for some special patented ones, which are expensive).
1. Chrome molybdenum steel
This steel has good impact resistance, good hardness and toughness, but the material is expensive.
2. Chrome vanadium steel
This material has good strength and toughness, which is the ideal material for making wrenches, screwdrivers, etc. The price is not so expensive. It is the general material for screwdrivers in daily life.
3. Carbon steel
Carbon steel refers to a type of steel that does not add other specific elements and its carbon mass fraction is less than 2.11%. It has the advantages of high hardness, high strength and poor toughness. This steel is not suitable for screwdrivers, but is widely used in some general tool materials.
4. S2 steel
This alloy steel is a kind of excellent impact resistant steel, used for making high hardness hex wrench, screwdriver, etc. Made of this steel after heat treatment, the tool has a high enough hardness. The tools also have good wear resistance, and they have certain strength and toughness.
From the aspect of the steel strength, chromium molybdenum steel is more outstanding. From the overall comprehensive cost performance, chromium vanadium steel is a better choice.
