15CrMo Steel Pipe Features

For the 15CrMo steel pipe, the microstructure 15CrMo steel pipe plays an important role in the pitting corrosion resistance of the alloy. Various phases, such as sulfide inclusions, ferrite. Phases, sensitized grain boundaries, and welds all have a decisive influence on the pitting resistance of steel, which are sites where pitting corrosion is sensitive. For the marcelitic 15CrMo alloy steel pipe with relatively complicated microstructure and the martensitic 15CrMo steel pipes whose microstructure is very sensitive to the heat treatment process, the relationship between pitting corrosion and composition phase is more closely. It should be noted that the inclusion of composite manganese sulfide inclusions is a more sensitive site for pitting corrosion. Therefore, when smelting 15CrMo steel pipe, aluminum deoxidizer should be avoided.

15CrMo steel pipe features

1. 15CrMo steel pipe specifications: The maximum specification of 15CrMo steel pipe production line is 400400mm20mm-600mm600mm30mm.
2, 15CrMo steel pipe high strength. In order to reduce the self-weight, improve the safety performance such as earthquake resistance and shock resistance, high-strength steel has been widely used at home and abroad. The material strength limit has reached 630mpa or even higher. The tensile strength of 15CrMo steel tube base material produced by large-scale 15CrMo steel pipe production line can reach 630mpa, Japanese production line. The produced product zui has a high strength of only 550mpa, which is a difference of 15.
3, 15CrMo steel pipe products are super thick. The maximum thickness of the rectangular tube produced by the large-scale 15CrMo steel pipe process can reach 19mm. The relative thickness of the product is also an important indicator of the difficulty of cold forming. The 15CrMo steel pipe is represented by the edge thickness, and the product with a side thickness ratio of less than 10 has a high The molding difficulty, the 15CrMo steel pipe produced by the large-scale 15CrMo steel pipe process, the thickness of the small-section large wall thickness product reaches 7, such as 100mm100mm14mm, 120mm120mm16mm and so on.

15CrMo steel pipe processing

1. One end of the 15CrMo steel pipe is sturdy with wooden wedges and stands up (note: you need to leave the outer head for easy dialing), use the sand for the construction of the sieve that has been fired with fire, and slowly fill it with a funnel. Go in, while tapping the pipe wall with a hammer, while filling, until the dry sand does not have any looseness in the pipe, fully fill it, and then tap another identical wooden wedge.
2. On the working platform, draw a large sample of welded 15CrMo steel pipe: the outer radius is 50 OD/2, the inner diameter is 50-OD/2, and the scorpion is spot welded at the beginning of the bend and the stop to prevent Overdone or owe.
3, 15CrMo steel pipe under the fire, you can also use a welding torch to roast. It’s easier to get off the fire, but it’s okay to pick it up slowly, but if you use a steam gun to bake it, you should pay attention to the 15CrMo steel pipe for a period of time. Be careful to bake the same part of the bottom of the platform. Fire, otherwise it will be flat!
4. If the 15CrMo steel pipe is found to be under-filled (not enough angle) or too long (angle is large), it can be corrected by pouring cold water inside the fillet or heating the outside and vice versa.
The 15CrMo steel pipe can be seen from the above method. It also has strict requirements on the shape. The shape of a 15CrMo steel pipe also determines where it is used. According to different shapes, we can also distinguish 15CrMo steel pipe between various fields. In the future, we will innovate the 15CrMo steel pipe to make it the perfect 15CrMo steel pipe.
