Why is stainless steel becoming more and more common in life?

Excellent corrosion resistance

First of all, stainless steel is mainly composed of iron, chromium, nickel and other elements, of which chromium is the key element of stainless steel corrosion resistance. Chromium can form a dense oxide film on the surface of stainless steel, that is, passivation film, which can prevent oxygen, water and other corrosive media from further eroding the stainless steel matrix. When the surface of stainless steel is slightly corroded, this passivation film is able to quickly self-repair, thereby maintaining its corrosion resistance.

Secondly, stainless steel may also contain other alloying elements, such as molybdenum, titanium, niobium, etc., which can further improve the corrosion resistance of stainless steel. For example, molybdenum can enhance the corrosion resistance of stainless steel in reducing media, and titanium and niobium can improve the corrosion resistance of stainless steel in the Marine environment.
In addition, the corrosion resistance of stainless steel is also related to its surface state. The smoother and cleaner the surface of stainless steel, the better its corrosion resistance. Because the smooth surface is not easy to hide dirt and dirt, it can reduce the contact area between the corrosive medium and the stainless steel matrix; The clean surface can reduce the adhesion and accumulation of corrosive media, thus delaying the corrosion process.

High strength and hardness

First of all, the alloying elements in stainless steel such as chromium, nickel, molybdenum, titanium, etc., form a stable solid solution or compound in stainless steel, which can enhance the crystal structure and grain boundary strength of stainless steel, thereby improving its overall strength and hardness. In particular, chromium is not only the key to improving the corrosion resistance of stainless steel, but also to increase the strength of stainless steel through solid solution strengthening.

Secondly, the heat treatment process also has an important impact on the strength and hardness of stainless steel. Through heat treatment processes such as quenching and tempering, the microstructure in stainless steel can be transformed to adjust its microstructure and properties. For example, quenching can convert austenite in stainless steel into martensite, which is a high-strength, high-hardness microstructure that can significantly improve the strength and hardness of stainless steel. Tempering can eliminate the internal stress and brittleness generated during quenching, while maintaining the high strength and hardness of stainless steel.
In addition, the microstructure of stainless steel also has an important impact on its strength and hardness. The grain size, shape and distribution in stainless steel will affect its mechanical properties. By controlling the smelting and processing process of stainless steel, fine grains and uniform organizational structure can be obtained, thereby improving the strength and hardness of stainless steel.

Easy to process and form

1. High plasticity
Stainless steel has a high plasticity, which means that during processing, it can be more easily stretched, compressed, bent and twisted to shape into a variety of desired shapes. High plasticity makes stainless steel not easy to break or crack during processing, improving the success rate and efficiency of processing.
2. Good machinability
Some stainless steel types, such as AISI 202 stainless steel, have good machinability. In the cutting process, the tool wear is lighter and the cutting force is smaller, which can not only extend the service life of the tool, but also improve the processing efficiency. Therefore, stainless steel materials can be easily processed by turning, milling, drilling and other cutting methods.
3. Diversified processing methods
Stainless steel can be formed by a variety of processing methods, including but not limited to cold working, hot working, forging, stamping, drawing, etc. Cold processing such as cold rolling, cold drawing, etc., can process stainless steel at room temperature, while hot processing such as forging, hot rolling, etc., needs to be carried out at high temperatures. These diverse processing methods allow stainless steel to adapt to different processing needs and scenarios.

4. Strong surface treatment ability

Stainless steel has a smooth and high flatness surface, which allows it to perform some high-precision machining operations, such as polishing. Polishing can further improve the finish and beauty of the stainless steel surface, while enhancing its corrosion resistance. In addition, stainless steel can also be changed by drawing, mirror treatment, sandblasting and other surface treatment methods to change its appearance and texture.
5. Stable performance
Stainless steel can maintain stable performance during processing, and is not easy to deform or reduce performance due to processing. This is due to its unique alloy composition and microstructure, so that stainless steel can maintain high strength and hardness during processing.
