Haynes welding
Supplier
The supplier Evek GmbH offers to buy Heine's alloy at the best price in this segment of rolled products. We offer welded European steels from specialized warehouses of Evek GmbH. Timely delivery is ensured by representatives in Eastern European cities.
Welding Challenges
Welding Hines alloy entails a number of difficulties due to the fact that the transition of the metal from solid to liquid state has a tendency to form pores. The main source of pores in argon arc welding is nitrogen. After the weld cools, nitrogen gas forms pores inside the metal.
Crystallization cracks
Welding is associated with a high propensity for the weld to develop crystallization cracks at the boundaries of large grains, which have a transcrystalline structure. To prevent cracking, it is necessary to limit the content of harmful impurities and introduce elements that bind sulfur in the most refractory compounds.

| P | Mn | C | S | Si | Mo | Ni | Cr | Co | W | Fe |
|---|---|---|---|---|---|---|---|---|---|---|
| ≤0,4 | 1,0-2,0 | 0,05-0,15 | ≤0,03 | ≤0,4 | 2,5-3,5 | 9,0-11,0 | 19,0-21,0 | balance | 14-16 | 3,0 |
Optimization of welding
An important condition is the cleanliness of the surface of welding materials and base metal as well as the binding of hydrogen. This is solved by introducing strong deoxidants into the weld pool (titanium, aluminum, etc.), as well as by using coatings or fluxes that can convert hydrogen into stable volatile compounds.
