As a kind of widely used stainless steel pipe, industrial stainless steel seamless pipe has outstanding advantages. One of the outstanding features should be easy to manufacture. When manufacturing industrial stainless steel seamless pipes, tempering is an important step. Do you want to know what the purpose of tempering is? Here I can give you the answer.
The purpose of tempering is to transfer quenched martensite into tempered martensite so that the internal stress can be eliminated. Also, the industrial stainless steel seamless pipe features can be of high hardness, abrasion resistance and red hardness. What's more, by tempering, stable size can be achieved and the mechanical properties can be improved. As a result, the industrial stainless steel seamless pipe can meet the needs of their work. Generally the tempering temperature is 540 ~ 570°C. In order to ensure the effect of tempering, you should pay attention to the following problems:
1. After quenching, the industrial stainless steel pipe should have tempering treatment immediately. Otherwise the residual austenite will show signs of stabilization.
2. The tempering temperature should be uniform, preferably in nitrate furnace.
3. Every time the industrial stainless steel seamless pipe is tempered, the pipe should be cooled to room temperature before the next time of tempering.
4. Cutting tools used for tempering should be cooled to room temperature before cleaning. Otherwise, stainless steel tube is easy to crack.
Tempering treatment makes industrial stainless steel seamless pipe features like moderate hardness to be more suitable for use. There are many methods of tempering. They are low temperature tempering, medium-temperature tempering and high-temperature tempering. Each method has its own advantage. The steel pieces can obtain better mechanical properties known as high strength, toughness and adequate hardness. That is all for tempering of industrial stainless steel seamless pipe.
