Effect of folding performance
1.manganese;Can improve the strength of steel, can weaken and eliminate the bad influence 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.
2. silicon;It can improve the hardness of steel, but plasticity and toughness decline, electrical steel contains a certain amount of silicon, can improve the soft magnetic properties.
3. tungsten;Can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel.
4. chromium;Can improve the hardenability and wear resistance of steel, can improve the corrosion resistance and oxidation resistance of steel.
In order to improve the corrosion resistance, the general steel pipe (black pipe) was galvanized.Galvanized steel pipe is divided into hot galvanized and electric steel zinc two kinds, hot galvanized galvanized layer thick, low cost of electric galvanized, so there is a galvanized steel pipe.
