When seamless steel tubes are cold drawn, they can be compared due to drawbacks such as subsistence cracks in hot rolled billets, or cracks that occur during the operation after the high-precision cold-drawn tubes have been made into cylinders. Seamless steel pipe is usually brittle cracks. Welded seamless steel pipe, brittle cracking is caused by a variety of reasons.

For example, when there are precipitates on the grain boundaries, they will attack whether they are stronger or weaker than the matrix. All are responsible for cracking of seamless steel tubes. The segregation of inclusions at grain boundaries is also a cause of seamless steel pipe cracking. In effect, cold-drawn seamless steel tubes, despite being subjected to small alternating loads, can cause fatigue and cracking.

In general, look at the appearance. Mechanical property guidelines for planning the operation of hydraulic (pneumatic) components assume that the material is homogeneous, continuous and isotropic Cold Drawn Seamless Steel Tubes. Adherence to this method indicates that it is considered safe to plan for the unexpected cracking events that sometimes occur.

Appearance of Cracking in Cold Drawn Seamless Steel Tubing, See Welded Steel Tubing during low-stress brittle cracking of high-strength cold-drawn seamless steel tubing. The texture of the material is far from uniform and isotropic. Cold Drawn Seamless Steel Pipe, Cracks, inclusions and porosity in the structure. All of these shortcomings can be viewed as microcracks in speculation. The appearance of cracking in cold drawn seamless steel pipe.

In addition, seamless steel pipe factory, seamless steel pipe manufacturer tells you that brittle cracking is also related to the working temperature of the parts. When the temperature falls below a certain temperature value, the cold drawn seamless pipe product will become brittle, and its effect will result in a much reduced workload. This appearance is known as cold embrittlement, so the working temperature of the component must also be followed when planning in order to select materials suitable for the temperature of cold embrittlement change.
