What will be the effect of metal elements in the production of spiral pipe?

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

2, silicon; it can improve the hardness of spiral steel pipe, but plasticity and toughness decline, electrician spiral steel pipe contains a certain amount of silicon, can improve the soft magnetic properties.

3, chromium; can improve the hardenability and wear resistance of spiral steel pipe, can improve the corrosion resistance of spiral steel pipe and oxidation resistance. In order to improve the corrosion resistance of anti-corrosion spiral steel pipe tube, the general anti-corrosion spiral steel pipe (black pipe) galvanized.

4, sulfur; is a spiral steel pipe in the harmful impurities, high sulfur spiral steel pipe at high temperatures for pressure processing, easy to brittle, usually called thermal embrittlement

5, carbon; the higher the carbon content, just the higher the hardness, but its plasticity and toughness is worse.

6, manganese; can improve the strength of spiral steel pipe, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of spiral steel pipe, high alloy spiral steel pipe with high manganese content (high manganese spiral steel pipe) has good wear resistance and other physical properties.

7, phosphorus; can make the spiral steel pipe plasticity and toughness decreased significantly, especially in the low temperature is more serious, this phenomenon is called cold brittleness. In the high-quality spiral steel pipe, sulfur and phosphorus should be strictly controlled. But on the other hand, in the low carbon spiral steel pipe contains high sulfur and phosphorus, can make its cutting easy to break, to improve the cutability of spiral steel pipe is favorable.
