The influence of metal elements in the production of SSAW steel pipe

What is the influence of metal elements in the production of SSAW steel pipe? Next, we will give you an introduction.

Tungsten can improve the red hardness and thermal strength of SSAW steel pipe, enhancing its wear resistance.

Silicon can improve the hardness of SSAW steel pipe, but it also reduces plasticity and toughness. In SSAW steel pipe used for electrical applications, a certain amount of silicon is added to improve the soft magnetic properties.

Chromium can enhance the hardenability and wear resistance of SSAW steel pipe, as well as improve its corrosion and oxidation resistance. To further improve the corrosion resistance of anti-corrosion SSAW steel pipe, the general anti-corrosion SSAW steel pipe (black pipe) is often galvanized.

Sulfur is a harmful impurity in SSAW steel pipe. High sulfur content in SSAW steel pipe makes it prone to brittleness when subjected to high-temperature pressure processing, a phenomenon known as thermal embrittlement.

The higher the carbon content, the harder the SSAW steel pipe, but its plasticity and toughness are reduced.

Manganese can improve the strength of SSAW steel pipe, mitigate and eliminate the adverse effects of sulfur, and enhance its hardenability. High-alloy SSAW steel pipe (with high manganese content) offers excellent wear resistance and other physical properties.

Phosphorus can significantly reduce the plasticity and toughness of SSAW steel pipe, especially at low temperatures, which can lead to cold brittleness. In high-quality SSAW steel pipe, sulfur and phosphorus content should be strictly controlled. However, for low-carbon SSAW steel pipe, high sulfur and phosphorus content can make it easier to cut, improving the machinability of the pipe.
