What is the performance of the galvanized pipe in Ji'nan? Today, it is a small compilation to popularize the properties of galvanized pipe to make you better understand the galvanized pipe. It is convenient to use galvanized pipe in the future to make the use of galvanized pipe more important. The elements of galvanized pipe include carbon, sulfur, phosphorus, manganese, silicon, tungsten and chromium.
1 carbon; the higher the carbon content, the higher the hardness of the steel, but the plasticity and toughness are worse.
2 sulfur; it is a harmful impurity in steel. The steel with high sulphur is brittle at high temperature and is usually called hot brittleness.
3 phosphorus can reduce the plasticity and toughness of steel obviously, especially at low temperature. This phenomenon is called cold brittleness. In high quality steel, sulfur and phosphorus should be strictly controlled. But in the other way, high sulfur and phosphorus in low carbon steel can be easily broken and it is beneficial to improve the machinability of steel.
4 manganese; Ji'nan galvanized pipe can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel with high manganese content has good wear resistance and other physical properties.
5 silicon; it can improve the hardness of steel, but its plasticity and toughness decrease. The steel used in Electrotechnics contains a certain amount of silicon, which can improve soft magnetic properties.
6 tungsten can improve the hardness and thermal strength of steel and improve the wear resistance of steel.
7 chromium can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steel.
