Measures in weld of the DIN17175 10CrMo910 steam tube in the boilers

Lots of DIN17175 10CrMo910 steam tube user want to buy the high-quality. Katalor is DIN17175 10CrMo910 steam tube exporter and stockist, we put the quality in the first. We are willing to set a long cooperation with customers, so we will introduce somes measures to solve DIN17175 10CrMo910 steam tube problems.

Because DIN17175 10CrMo910 steam tubehas Cr and Mo, belongs to heat resistant steel tube. So thatit is easy to appear the defects such as hardened microstructure in welding process.
In view of the above problems, we should take countermeasures from the following aspects:

1. Preheat before welding, slow down cooling rate, make weld and nearby hydrogen escape as far as possible, reduce welding stress.
2. Using preheating before welding and controlling interchannel temperature, the reheat crack can be effectively controlled by.
3. In the DIN17175 10CrMo910 steam tube welding process, the ultra-low hydrogen R407 electrode and TIGR40 wire should be used to strictly control the content of harmful impurity elements in the weld seam and to reduce the content of Si and Mn.
4. In order to reduce the width and degree of softening zone, reasonable preheating temperature should be selected before DIN17175 10CrMo910 steam tube welding. Reasonable control of interchannel temperature and line energy, heat treatment after normalizing high temperature tempering.

Katalor has professional team to produce DIN17175 10CrMo910 steam tube, so we have many customers are from all over the world. If you have any need in DIN17175 10CrMo910 steam tube, you can contact us freely. We can supply DIN17175 10CrMo910 steam tube with your requirements.
