Technical characteristics
Steel of grade HN35WTJU is a high-alloyed heat-resistant alloy on an iron-nickel basis. It is used in manufacture of floating details that work at temperatures of 900−1000°C. This alloy relates to a category of ferritic-austenic steels. In comparison with austenic steels, it has almost twice as large strength, higher resistance to intercrystalline corrosion, increased resistance to corrosion cracking in alkaline and chloride environment. A usage of austenic and ferritic steels directly depends on conditions of exploitation.
Manufacture
An iron basis is alloyed with 34−38% of nickel, 14−16% of chrome. Titanium (1,1−1,5%), copper (<0.25%), phosphorus (<0.03%), mangan (<1-2%), wolframium (2,3-3,5%), molybdenum (<0,3%), sulfur (0,02%) should be added to charge mixture in the capacity of masteralloys.

Alloy smelts in open electric furnaces with a help of vacuum arc remelting. Jumping-up temperature of semi-fabricates is 1170 °C at the beginning; in the end a temperature is 850 °C. A finished product cools in the air.

Welding
| Type | Description |
| limitedly weldable | welding is possible at heating to 100−120°С and last heat treating |
| hardly weldable | in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treatment (annealing) after welding |
| weldable without stint |
welding is done without further heat treating or previous heating |
Application
This alloy is used in manufacture of disks, compressor rotor blades, gas-turbine engine with a limited service life at a temperature of 550−750°С.
