DIN 17175 Seamless Steel Tubes For Elevated Temperatures.DIN 17175 St35.8 steel tube is concerned, steels that have a good mechanical properties at a higher temperature, up to 6 00 °C, and even under long-term load, are called heat-strength steels.
The DIN 17175 ST35.8 seamless carbon steel based tubes, produced in our factory are much appreciated for their ability to withstand high pressure. This feature of the DIN 17175 ST35.8 Carbon Steel Superheater Tubes, makes them a high in demand asset to various industries across several key sectors. In fact, the supply of this particular grade of ST35.8 DIN 17175 Boiler Tube is rather high these days. This is because the ST35.8 Pipe is considered to be an essential product which can be used during the installation of the boilers as well as in tanks constructions.

Seamless Steel Tubes For Elevated Temperatures
As far as DIN 17175 is concerned, steels that have a good mechanical properties at a higher temperature, up to 6 00 °C, and even under long-term load, are called heat-strength steels.
DIN 17175 St35.8 Seamless Steel Tubes can be used to manufacture steam boilers, pipes, pressure vessels and instruments operating at temperatures up to 600 ° C and at high temperatures.
Manufacturing method
DIN 17175 St35.8 Seamless Steel Tubes may be produced by hot rolling, cold rolling, hot pressing, hot drawing or cold drawing.
The tube steel can be smelted in a flat furnace or an electric furnace according to the oxygen blowing method, and all steels should be cast in a static manner.
heat treatment temperature of DIN 17175 St35.8 Seamless Steel Tubes
Hot working is possible from 1100 to 850°C, and the temperature can be reduced to 750 °C during processing.
