DIN EN10297 E235 E275 E470 Seamless Steel Tubes for Mechanical and General Engineering Purposes
The Seamless Steel Tubes are produced by Cold Drawn or Cold Rolled, for small diameters below 88.9mm, the bigger diameter are produced by hot rolling.
These steel tubes will be used for mechanical engineerings, could be also used as mother tube for further cold drawn production to achieve better tolerance and surface smoothness as precision steel tubes.
