Several factors affecting the performance of galvanized steel pipe

Galvanized steel pipe is divided into cold galvanized pipe and hot-dip galvanized pipe, hot-dip galvanized zinc coating is thick, with a uniform coating, strong adhesion, the following to introduce you to several factors affecting the performance of galvanized steel pipe. 1, the higher the carbon content, the higher the hardness of galvanized steel pipe, but its plasticity and toughness is worse.

2, high sulfur content of galvanized steel pipe is easy to produce cracks under high temperature and high pressure processing.

3, phosphorus can make the plasticity and toughness of galvanized steel pipe significantly reduced, especially at low temperatures, in high quality galvanized steel pipe, sulfur and phosphorus should be strictly controlled. Low carbon steel with high sulfur and phosphorus content, easy to cut, conducive to improving the mechanical properties of steel.

4, manganese can improve the strength of galvanized steel pipe, can eliminate the adverse effects of sulfur, improve the hardenability of galvanized steel pipe. High manganese content of high alloy steel (high manganese steel) has good wear resistance and other physical properties. 5, silicon it can improve the hardness of galvanized steel pipe, but plasticity and toughness decreased. Electrical steel containing a certain amount of silicon can improve its soft magnetic properties.

6, tungsten can improve the red hardness and thermal strength of galvanized steel pipe, can improve the wear resistance of steel.
