Seamless steel pipe is composed of various elements in steel. These elements are combined in different proportions to form different mechanical properties of seamless steel pipes. The amount of any element will directly affect the mechanical properties of seamless steel pipes. So what role do these elements play in the composition of steel? Let's take a look at the elements that affect the performance of seamless steel pipes:
When the carbon content increases, the yield point and tensile strength increase, but the plasticity and impact properties decrease. Too high carbon content will easily lead to unqualified intergranular corrosion. The boundary between steel and iron is controlled by the carbon content: <2.11% is steel.
Chromium significantly increases the strength, hardness and wear resistance of steel, but at the same time reduces ductility and toughness.
Nickel can improve the strength of steel, but also can maintain good plasticity and toughness of steel.
Nitrogen increases the strength, low temperature toughness and weldability of steel. Increase pragmatic sensitivity. An appropriate amount of nitrogen can improve the pitting corrosion resistance and strength of stainless steel.
