EN 10305-1 E355+sr seamless cold drawn steel tubes supplier


Standard EN 10305 covers steel produced precision tubes. This standard includes delivery conditions for six different parts. Part 1 or as referred to as EN 10305-1 refers to Seamless cold drawn precision tubes. These precision tubes are specifically designated with the letter E, thereby the manufacturing processes adhere to the standard and keep tight tolerances, making them well suited for use as machine parts. This is because a precision steel tube en 10305-1 is identical to the system it is to be attached to.

Hence, there is no error, nor is there any wiggle room for a mismatch to occur in the system. Therefore the use of en 10305-1 material to make cold drawn precision tube is a welcome one. In addition to being designated as machine steels, there are many grades with differing yield strengths that could be used in the production of en 10305-1 equivalent tubes. Generally, most buyers prefer the use of steels that have minimum yield strength of about 235 N/mm2 or 355 N/mm2. The en 10305-1 material are often designated with a relevant treatment the tubes has been processed with. For instance, the tube with the designation en 10305-1 E235+n would indicate that the steel is to be delivered in a normalized condition. There are several benefits of using an e355+sr en 10305-1 Cold drawn seamless precision tube. Not only do they have a tighter level of tolerances, but they have better mechanical property and hardness. Moreover, the cold drawing improves the surface of the en 10305-1 e235+c tube as they are smoother.
