Anti-corrosion steel pipe is a steel pipe that can be effectively prevented or slowed down by chemical or electrochemical reaction in the process of transportation and use of corrosion phenomena after anti-corrosion process processing. According to statistics, the annual steel pipe corrosion direct economic loss of more than 280 billion.
 
Elements that have an impact on the performance of anti-corrosion steel pipe.
 
1, tungsten; can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel
 
2, silicon; it can improve the hardness of steel, but plasticity and toughness decline, electrician's steel contains a certain amount of silicon, can improve the soft magnetic properties
What are the elements that have an impact on the performance of anti-corrosion steel pipe
 
3, chromium; can improve the hardenability and wear resistance of steel, can improve the corrosion resistance of steel and antioxidant effect. To improve the corrosion resistance of anti-corrosion steel pipe, the general anti-corrosion steel pipe (black pipe) galvanized
 
4, sulfur; is a harmful impurities in steel, high sulfur content of steel at high temperatures for pressure processing, easy to brittle cracking, usually called thermal embrittlement
 
5, carbon; the higher the carbon content, just the higher the hardness, but its plasticity and toughness will be worse
 
6, manganese; can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, high alloy steel with high manganese content (high manganese steel) has good wear resistance and other physical properties
 
7, phosphorus; can make the steel plasticity and toughness significantly reduced, especially at low temperatures more serious, this phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus to strictly control. But from another point of view, in low carbon steel contains higher sulfur and phosphorus, can make its cutting easy to break, to improve the machinability of steel is beneficial.
