Austenitic stainless steel. It contains more than % chromium about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling, which is connected by special thread for important threading pipe). For some special pipes, outer thickening or inner and outer thickening).Slatina,SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.And stainless steel are molybdenum containing stainless steels. The molybdenum content of stainless steel is slightly higher than that of stainless steel. Due to the molybdenum content in stainless steel, when the concentration is lower than % and higher than %, stainless steel has a wide range of applications. Stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment.Antony,And stainless steel are molybdenum containing stainless steels.

This material without titanium and niobium has an inherent tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust freeThe welding alloy has good weldability. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, large quantity, high quality and low price. Fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable. The performance of the alloy is that the welding metal and heat deteriorated part still maintain the same corrosion resistance, strength and toughness as the base metal. It is not difficult to weld, but its welding procedure needs to be designed so that after welding, it can maintain a good phase balance and avoid the precipitation of harmful metal phase or non-metal phase. Welding can be carried out in the following equipment: GTAW (TIG); GMAW (MIG); SMAW (“stick” electrode); SAW; FCW; And paw stainless steel features: compared with L and L austenitic stainless steel, duplex stainless steel alloy has superior performance in spot corrosion and crack corrosion resistance. It has high corrosion resistance. Compared with austenite, it has lower thermal coefficient and higher thermal conductivity.Austenitic stainless steel austenitic stainless steel is developed to overcome the lack of corrosion resistance and brittleness of martensitic stainless steel. The basic composition is crl% and Ni%, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.consumption,The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti, Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of crc on the grain boundary.Crimping: during crimping, the convex part of the pipe fitting is placed in the concave groove of the die, and the jaw is perpendicular to the pipe axis.Model & mdash; The addition of sulfur improves the processability of the material.

Design and research of high precision stainless steel pipe stainless steel pipe has many advantages, such as high strength, good corrosion resistance, strong impact resistance and so on, which makes it widely used in various fields of life. With the continuous improvement of automation, people have higher and higher requirements for the cutting quality of stainless steel pipe. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision, high automation, high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, the intermittent cutting method of planetary bisymmetric eccentric installation can reduce the cutting deformation of stainless steel pipe and improve the cutting accuracy; Secondly, the tool of the intermittent stainless steel pipe cutting machine is eccentrically installed on the planetary gear to complete the rotation at the same time of revolution. Therefore, only one main motor can drive two tools to rotate. The mechanical structure reduces the use of the motor, improves the use efficiency of the motor and reduces the manufacturing cost of the equipment; Then, the main components of the intermittent pipe cutter are analyzed by using SolidWorks D solid software and ANSYS finite element analysis software. ANSYS software verifies the rationality of the structure and improves the service life of the pipe cutter. At present, there are still many deficiencies in pipe cutting in China which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision high automation, high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, and it is also the inevitable trend of the further development of China's industry. Firstly, the cutting characteristics of the intermittent stainless steel pipe cutter in the cutting process are analyzed, and the cutting force in the cutting process is calculated.
