Steel pipe is a metal product widely used in construction, machinery, automobile, aerospace and other fields, and its performance directly affects the use effect and service life. In the steel pipe production process, there are many factors that will affect the performance of the steel pipe, let's take a look in detail below.

Carbon: The higher the carbon content, the higher the hardness of the steel pipe, but the worse the plasticity and toughness.

Sulfur: It is a harmful impurity in steel pipes. If the steel contains high sulfur content, it is easy to become brittle at high temperatures, which is usually called hot brittleness.

Phosphorus: it can significantly reduce the plasticity and toughness of steel, especially at low temperatures. This phenomenon is called cold brittleness. In high-quality steel, sulfur, and phosphorus should be strictly controlled. On the other hand, the high content of sulfur and phosphorus in low-carbon steel can make it easy to cut, which is conducive to improving the cutting performance of steel.

Manganese: it can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with manganese content has good physical properties such as wear resistance.

Silicon: It can improve the hardness of steel, but its plasticity and toughness decrease. But silicon can improve the soft magnetic properties.

Cangzhou Shenlong Pipe Manufacturing Co., Ltd. cooperates with Baosteel and Baogang to produce large-caliber seamless steel pipe, straight-seam welded pipe, spiral steel pipe, and pipe fittings. The products comply with API, ASTM, DIN, BS, and JIS standards, and can accept SGS, BV, and other inspections. The products are used in oil, natural gas, bridge, water conservancy, and other large-scale projects, which are worthy of trust.
