Hardware tools are indispensable tools in our daily lives, and their materials have a crucial impact on the quality and service life of tools. In the production process of hardware tools, commonly used materials include carbon steel, chromium vanadium steel, S2 tool steel, etc.
Carbon steel is one of the most common hardware tool materials, and its main components are carbon and iron. According to the carbon content, it is divided into high, medium, and low carbon steel. High carbon steel is generally used for tools, which has high hardness, strength, and poor toughness. Wrenches generally use this material.
Chromium vanadium steel is an alloy steel containing chromium and vanadium. Its comprehensive strength and toughness are superior to carbon steel, making it an ideal material for high-quality tools.
S2 tool steel is a high-strength alloy steel with superior comprehensive properties compared to chromium vanadium steel. It has strong plasticity, high strength and hardness, as well as excellent impact toughness and fatigue strength. It is often used in the manufacturing of cutting tools. However, the price of S2 tool steel is relatively high and the production difficulty is also high.
In addition to the three commonly used hardware tool materials mentioned above, there are many other materials to choose from, such as stainless steel, tungsten steel, etc. When selecting hardware tool materials, it is necessary to choose according to the specific usage environment and needs to achieve the best usage effect. In short, the material of hardware tools has a crucial impact on the quality and service life of the tools. When selecting hardware tools, it is necessary to choose according to the specific usage environment and needs to achieve the best usage effect.
Hardware tools should also be categorized, with different types using different types of steel.
Chromium vanadium steel is an alloy tool steel with the addition of chromium vanadium alloy elements. After heat treatment, the hardness is above 60HRC (Rockwell hardness), and it has good wear resistance under specific working conditions. It is suitable for strong impact and high wear environments, and is suitable for the production of tools such as wrenches.
High carbon steel, commonly known as tool steel, has a carbon content ranging from 0.60% to 1.70% and can be quenched and tempered. Hammers, pry bars, etc. are made of steel with a carbon content of 0.75%; Cutting tools such as drills, taps, and reamers are made of steel with a carbon content of 0.90% to 1.00%.
