1. The basic temperature resistance of carbon steel pipes
As a commonly used engineering material, carbon steel pipe has a wide range of applications in many industries. Its temperature resistance is an important indicator to measure its quality and range of use. Ordinary carbon steel pipes, without special treatment, are generally safe to use in the temperature range of -40°C to 450°C. This range meets the needs of most industrial applications.
However, when the ambient temperature exceeds this range, the performance of carbon steel pipes may be affected. At extremely low temperatures, steel pipes can become fragile and prone to breakage; In a high-temperature environment, the mechanical properties of steel pipes may be reduced, or even deformed or damaged.
2. The influence of alloying elements on temperature resistance
In order to improve the temperature resistance of carbon steel pipes, some alloying elements, such as chromium, molybdenum, etc., are often added in the manufacturing process. The addition of these elements can significantly improve the high temperature resistance of the steel pipe, allowing it to maintain stable mechanical properties at higher temperatures.
For example, the addition of chromium can improve the oxidation and corrosion resistance of steel, so that steel pipes can work for a long time at high temperatures without being easily damaged. The addition of molybdenum can enhance the strength and toughness of steel and improve its stability at high temperatures.
The temperature resistance range of alloy carbon steel pipes that have undergone specific heat treatment can be extended to more than 600°C or even higher. This high-performance alloy steel pipe has a wide range of applications in petrochemical, electric power, aerospace and other fields.
