DIN 2391-1 Seamless Precision Steel Tubes supplier

Besides exhibiting high precision, these products tend to have a good surface quality and great straightness as well. There are several specifications that cover high precision tubes including – din 17175, EN 10305-1 and din 2391. Another fitting advantage of using the specification is that the inner diameter of various steel grade Precision Seamless Tubes could be constructed into a hexagon shaped one.


Furthermore, the performance of these steel High precision Tubes tends to be superior, with the metal becoming relatively dense. Compared with solid steel pipes, including a steel round furnished seamless steel pipe, the precision seamless steel tubes are light in weight, even if both the varieties of pipes have the same bending and torsional strength. Amongst numerous steel sections, they gravitate towards the economical side. Therefore, the din 2391 seamless precision steel tubes widely adopted in the assembling of anatomical parts as well as mechanical parts. In addition, the manufacturing of EN 10305-1 Precision cold drawn steel tube can enhance material utilization, conserve materials and processing man-hours & simplify manufacturing processes, as well. Generally, precision seamless pipes such as din 17175 Cold Rolled Steel Tube are accepted in industries with high precision requirements, as opposed to their regular seamless counterparts, which are mostly applied without precision specifications. However, the expense of a precision seamless pipe of an identical specification tends to be much more high-priced in comparison to that of regular seamless pipes.


fushun is one of the large suppliers for high quality DIN 2391 Material. Carbon Steel DIN 2391 Tubing has various outstanding attributes to provide like having sturdiness, dimensional accuracy, toughness. DIN 2391 EN 10305 1 standard specifies the Seamless steel tubes used for Automobile and Mechanical.
