1.4962, X12CrNiWTiB16-13, St17-13W
1.4962 austenitic stainless steel, X12CrNiWTiB16-13 has good thermoplasticity due to good chemical balance of its elements, mainly used in turbine blades, gas turbines and heat-resistant products, containing W and Ti, tungsten improves its creep strength and high temperature machinery Properties, titanium is a very strong carbide former, it precipitates carbides at higher temperatures than chromium carbides form, so there is no carbon available to react with chromium.
The 1.4962 is suitable for high temperature assemblies and is selected in soldering processes and applications where intermittent heating up to 850 C° may occur. This material can be supplied in the annealed or hardened condition, resulting from warm working, but in the annealed condition its creep properties are lower than those in the strain hardened condition, and this difference is at lower temperatures than in the more pronounced at higher temperatures.
Ge Power grade: X10CrNiW17-13-3
